Exemplary embodiments of a server start / stop control device and a server start / stop control method of the present application will be described below in detail with reference to the accompanying drawings. The server start / stop control device and the server start / stop control method of the present application are not limited to the following embodiments.

  In the first embodiment, first, the problem is described with an example of the prior art, and then the server start / stop control device of the present application is described. In the first embodiment, a case will be described in which a plurality of servers constituting the communication network device are stopped when the communication network device connected to the communication network is stopped.

  First, the communication network will be described. FIG. 1 is a schematic diagram illustrating an example of a communication network according to the related art. For example, as shown in FIG. 1, a plurality of communication network devices are connected to the communication network. In FIG. 1, two communication network devices are shown, but actually more communication network devices are connected to the communication network. For example, the communication network is a local area network (LAN) or a wide area network (WAN).

  As shown in FIG. 1, the communication network device includes a front server, a DB server, and a log server, and executes processing in response to a request from a client device. For example, the communication network device communicates with other communication network devices or client devices to perform parallel distributed processing. In FIG. 1, one front server, one DB server, and one log server are shown. However, the communication network device may include a plurality of servers.

  The front server executes processing based on a processing request signal received from another communication network device. Specifically, as shown in FIG. 1, when the front server receives a processing request signal from another communication network device, the front server receives information (for example, user information, network information) necessary for processing according to the received processing request signal. Etc.) from the DB server and execute the process. Thereafter, the front server returns a processing result to the communication network device that has transmitted the processing request signal, and sends a processing log indicating the processing content to the log server.

  The DB server stores various data used for processing of the front server. For example, the DB server stores user information and network information, and responds to an information acquisition request from the front server as shown in FIG. 1 and sends a processing log indicating the response content to the log server.

  The log server stores the processing contents of the communication network device. Specifically, as shown in FIG. 1, the log server stores processing logs received from the front server and the DB server, respectively.

  The above-described communication network device may be realized by a server computer (for example, a blade server) in which each server is mounted on a piece of hardware and a plurality of them can be mounted, or one The server computer may be divided into a plurality of virtual computers, and the divided virtual computers may function as a front server, a DB server, and a log server, respectively.

  The server activation / deactivation control device controls activation and deactivation of each server on the communication network illustrated in FIG. FIG. 2 is a schematic diagram for explaining an example of processing of the server activation / deactivation control device according to the related art. In FIG. 2, the communication network device has one front server, one DB server, and one log server. In FIG. 2, only one communication network device is shown, but actually, a plurality of communication network devices are connected to the communication network, and the server start / stop control device Controls starting and stopping of the server to be configured.

  For example, as shown in FIG. 2, when the front server, DB server, and log server are stopped, if there is a restriction on the order of stopping, dependency of operations, processing after control failure, etc., server start / stop The control device transmits a stop request to the front server, DB server, and log server in response to a server stop command received from a maintenance person of the communication network, and stops each server. The details of this process will be described below with reference to FIGS.

  FIG. 3 is a diagram illustrating an example of the configuration of the server activation / deactivation control apparatus 200 according to the related art. As shown in FIG. 3, the server activation / deactivation control apparatus 200 according to the prior art includes a graphic user interface 210, a main processing unit 220, a communication network apparatus data file 231, a server configuration file 232, and a communication address data file 233. A log file 234, a communication network device / server identification unit 241, a communication address data acquisition unit 242, a server start / stop request unit 243, and a log management unit 244.

  The graphic user interface 210 is an interface that allows a maintenance person of the server start / stop control apparatus 200 to display an operation target or selection item with an icon or menu on the screen and operate it with a pointing device such as a mouse. For example, the graphic user interface 210 accepts input of stop commands for the front server, DB server, and log server.

  The main processing unit 220 performs overall control of processing by the server start / stop control device 200. The communication network device data file 231 stores an identifier for uniquely specifying a plurality of communication network devices arranged on the communication network. The server configuration file 232 stores an identifier for uniquely specifying a server constituting a plurality of communication network devices arranged on the communication network. For example, the server configuration file 232 stores identifiers for uniquely specifying the front server, DB server, and log server. The communication address data file 233 stores a communication address for each server constituting the communication network device.

  The log file 234 stores the processing content executed by the server start / stop control device 200. Specifically, the log file 234 stores the processing content of the server start / stop control device 200 stored by the log management unit 244 described later.

  Various information stored by the communication network device data file 231, the server configuration file 232, and the communication address data file 233 are registered in advance by a maintenance person.

  The communication network device / server identification unit 241 identifies a communication network device connected to the communication network based on the identifier stored by the communication network device data file 231. In addition, the communication network device / server identification unit 241 identifies the servers configuring the communication network device based on the identifier stored by the server configuration file 232. For example, the communication network device / server identification unit 241 identifies a front server, a DB server, and a log server that are targets of a stop command input by a maintenance person.

  The communication address data acquisition unit 242 acquires the communication address of the server identified by the communication network device / server identification unit 241 from the communication address data file 233.

  The server start / stop request unit 243 transmits a start request or a stop request to the server having the communication address acquired by the communication address data acquisition unit 242. The log management unit 244 stores the processing content by the server start / stop control device in the log file 234.

  Under such a configuration, the server start / stop control device 200 controls the operation of the server as described below. FIG. 4 is a sequence diagram illustrating an example of processing performed by the server activation / deactivation control apparatus 200 according to the related art. In FIG. 4, a case where a maintenance person inputs a server stop command via the graphic user interface 210 will be described. FIG. 4 shows processing after a start request command for starting or stopping a communication network device or a stop request command is registered in the server start / stop control device 200.

  In the prior art, first, as shown in FIG. 4, the maintenance person confirms the restrictions on the stop of the front server, DB server, and log server, and identifies the server to be stopped first as the front server (step S101). Then, by inputting the specified front server stop command, the server start / stop control device 200 is caused to stop the front server (step S102).

  When the front server stop command is input by the maintenance person, in the server start / stop control device 200 according to the prior art, the server start / stop request unit 243 is a request for the front server to stop the server. A process / OS stop request is transmitted (step S103). When the front server receives the process / OS stop request from the server start / stop control device 200, the front server transmits a process / OS stop response, which is a response to execute the process and OS stop, to the server start / stop control device 200 ( In step S104, the server is stopped (step S105).

  Upon receiving the process / OS stop response from the front server, the server start / stop control device 200 notifies the maintenance person through the graphic user interface 210 of a stop execution response indicating that the front server stop has been completed (step S106). . When the maintenance person confirms that the stop of the front server has been completed, the server to be stopped next is identified as the DB server (step S107), and the server start / stop control device is input by inputting the specified DB server stop command. 200 causes the DB server to stop (step S108).

  When a DB server stop command is input by the maintenance person, the server start / stop request unit 243 transmits a process / OS stop request to the DB server (step S109). Here, for example, as shown in FIG. 4, when a failure occurs in the DB server, the DB server stops the process / OS stop failure response, which is a response indicating that the stop of the process and the OS has failed. It transmits to the control apparatus 200 (step S110).

  Upon receiving the process / OS stop failure response from the DB server, the server start / stop control device 200 notifies the maintenance person of a stop execution response (failure) indicating that the DB server stop has failed via the graphic user interface 210. (Step S111). When the maintenance person confirms that the stop of the DB server has failed, the cause is investigated (step S112), the server to be stopped next is specified as the log server (step S113), and whether or not the server can be stopped based on the restriction. Determine whether. When it is determined that the server can be stopped (step S114), the maintenance person inputs the specified log server stop command to cause the server start / stop control device 200 to stop the log server (step S115).

  When the log server stop command is input by the maintenance person, the server start / stop request unit 243 transmits a process / OS stop request to the log server (step S116). When the log server receives the process / OS stop request from the server start / stop control device 200, the log server transmits a process / OS stop response, which is a response to execute the process and OS stop, to the server start / stop control device 200 ( In step S117, the server is stopped (step S118).

  Upon receiving the process / OS stop response from the log server, the server start / stop control device 200 notifies the maintenance person of a stop execution response indicating that the stop of the log server is completed via the graphic user interface 210 (step S119). .

  As described above, in the server activation / deactivation control device 200 according to the related art, when there is a restriction related to activation or deactivation between different server types, the maintenance person executes activation or deactivation of the server while checking the restriction. . This is because the conventional server start / stop control device cannot start or stop the server in consideration of restrictions on operation between different server types.

  For example, if the log server is stopped before the front server, the contents being processed by the front server cannot be recorded in the log server. Therefore, it is necessary to stop the front server before the log server, but the conventional server start / stop control device cannot cope with this. As described above, when there is a restriction on the stop order among the server types, the conventional server start / stop control apparatus cannot stop these servers.

  Also, for example, if there is a restriction that the log server cannot be stopped if the front server fails, it is necessary to determine whether the subsequent server can be stopped according to the execution result of the front server stop. In the conventional server start / stop control device, these servers cannot be stopped. That is, in a conventional server start / stop control device, if a server fails to start or stop due to a failure, all other servers cannot be started or stopped uniformly.

  Also, for example, in order to stop the log server when there is an operation dependency such that one log server holds a file that records the operating status and processing status of the two front servers, Although it is necessary to stop the front server in advance, the conventional server start / stop control device cannot perform such processing and cannot stop the log server.

  As described above, in the conventional server start / stop control device, there is a start or stop order between different server types, processing after a control failure is limited, or there is a dependency on server operation. When there is such a restriction, it is impossible to control the start and stop of the server. Therefore, conventionally, when there is such a restriction, the maintenance person controls the operation of the server while checking the restriction, and the server cannot be started and stopped quickly. In particular, when the number of servers connected to the communication network is large, the time required to start or stop the server becomes long and a work mistake may be induced.

  Therefore, the server activation / deactivation control device of the present application is intended to enable quick control of activation and deactivation of servers even when there are restrictions on activation or deactivation between different server types. And In the first embodiment, as described above, a case where a plurality of servers constituting a communication network device are stopped when the communication network device connected to the communication network is stopped will be described.

  FIG. 5 is a schematic diagram illustrating an example of a communication network according to the first embodiment. For example, as illustrated in FIG. 5, the communication network apparatus A and the server activation / deactivation control apparatus 100 are connected to the communication network according to the first embodiment. In FIG. 5, one communication network device is shown, but in reality, more communication network devices may be connected to the communication network. For example, the communication network is a LAN or a WAN.

  As illustrated in FIG. 5, the communication network apparatus A includes a front server 1, a front server 2, a DB server 1, a DB server 2, and a log server 1. For example, the front server 1 acquires network information and user information from the DB server 1, executes processing according to the processing request, and sends a log indicating the processing content to the log server 1. Further, the front server 2 acquires network information and user information from the DB server 2, for example, executes processing according to the processing request, and sends a log to the log server 1.

  The DB server 1 stores various data used for processing of the front server 1. For example, the DB server 1 stores user information and network information, responds to an information acquisition request from the front server 1, and sends a log indicating the response content to the log server 1. The DB server 2 stores various data used for processing of the front server 2. For example, the DB server 2 stores user information and network information, responds to an information acquisition request from the front server 2, and sends a log to the log server 1.

  The log server 1 stores the processing contents of the communication network device A. For example, the log server 1 stores logs received from the front server 1, the front server 2, the DB server 1, and the DB server 2, respectively.

  The above-described communication network device may be realized by a server computer (for example, a blade server) in which each server is mounted on a piece of hardware and a plurality of them can be mounted, or one The server computer may be divided into a plurality of virtual computers, and the divided virtual computers may function as a front server, a DB server, and a log server, respectively.

  The server activation / deactivation control device 100 quickly controls activation and deactivation of servers even when there are restrictions on activation or deactivation between different server types. FIG. 6 is a diagram illustrating an example of the configuration of the server start / stop control apparatus 100 according to the first embodiment.

  As shown in FIG. 6, the server activation / deactivation control apparatus 100 according to the first embodiment includes a graphic user interface 110, a main processing unit 120, a communication network apparatus data file 131, a server configuration file 132, and a communication address data file. 133, a communication network device start / stop file 134, a server start / stop condition file 135, a log file 136, a communication network device / server identification unit 141, a communication address data acquisition unit 142, and a server operation status acquisition unit 143. A server start / stop determination unit 144, a server start / stop request unit 145, and a log management unit 146.

  The graphic user interface 110 is an interface that allows an operator of the server activation / deactivation control apparatus 100 to display an operation target or selection item with an icon or a menu on a screen and operate it with a pointing device such as a mouse.

  The main processing unit 120 performs overall control of processing by the server start / stop control device 100. The communication network device data file 131 stores an identifier for uniquely specifying a communication network device arranged on the communication network. For example, the communication network device data file 131 stores an identifier “A” for uniquely identifying the communication network device A.

  The server configuration file 132 stores an identifier for uniquely identifying a server that configures a communication network device arranged on the communication network. For example, the server configuration file 132 stores identifiers for uniquely identifying the front servers 1 and 2, the DB servers 1 and 2, and the log server 1.

  The communication address data file 133 stores a communication address for each server constituting the communication network device A. The communication network device start / stop file 134 stores the server start order and stop order for each communication network device connected to the communication network. FIG. 7 is a diagram illustrating an example of information stored by the communication network device activation / deactivation file 134 according to the first embodiment.

  For example, the communication network device start / stop file 134 stores the stop order of servers for each communication network device, as shown in FIG. As an example, the communication network device activation / deactivation file 134 is associated with “communication network: A”, “1: front server 1, 2: front server 2, 3: DB server 1, 4: DB server 2, 5: Log server 1 ”is stored. Here, the above-described information means that the network device A stops in the order of the front server 1, the front server 2, the DB server 1, the DB server 2, and the log server 1.

  Returning to FIG. 6, the server start / stop condition file 135 is a restriction condition applied to start or stop of each server, and for each server, another server that satisfies a predetermined condition when starting or stopping the server. And a constraint condition indicating the contents of the condition is stored. Specifically, the server activation / deactivation condition file 135 stores, as the contents of the constraint conditions, the sequence of activation and deactivation, dependency between servers, and processing when control fails.

  More specifically, when starting or stopping each server, the server start / stop condition file 135 stops other low-priority servers or identifiers of other servers that need to be started or stopped in advance. Stores the thresholds of the processing amount in other servers, the relationship between the number of servers to be stopped and the thresholds, conditions such as the network connection status of other servers and the operating status of the OS so that each server can be started or stopped To do.

  FIG. 8 is a diagram illustrating an example of information stored by the server start / stop condition file 135 according to the first embodiment. For example, as illustrated in FIG. 8, the server start / stop condition file 135 according to the first embodiment stores a constraint for stopping the server for each server. For example, the server start / stop condition file 135 according to the first embodiment stores “stop after stopping the front server 1 and the front server 2” in association with “DB server 1”. Here, the above-mentioned information means that the front server 1 and the front server 2 need to be stopped in order to stop the DB server 1. Note that the information shown in FIG. 8 is merely an example.

  Returning to FIG. 6, the log file 136 stores the processing content executed by the server start / stop control device 100. Specifically, the log file 136 stores the processing contents of the server start / stop control device 100 stored by the log management unit 146 described later.

  Various information stored by the communication network device data file 131, the server configuration file 132, the communication address data file 133, the communication network device start / stop file 134, and the server start / stop condition file 135 are registered in advance by a maintenance person.

  The communication network device / server identification unit 141 identifies a communication network device connected to the communication network based on the information stored in the communication network device data file 131. In addition, the communication network device / server identification unit 141 identifies the servers configuring the communication network device based on the information stored in the server configuration file 132. For example, the communication network device / server identification unit 141 identifies the front server 1, the front server 2, the DB server 1, the DB server 2, and the log server 1 that constitute the communication network device A on the communication network.

  The communication address data acquisition unit 142 acquires the communication address of the server identified by the communication network device / server identification unit 141 from the communication address data file. The server operation status acquisition unit 143 communicates with each server connected to the network, and determines whether each server is operating normally. Specifically, the server operation status acquisition unit 143 acquires the operation state from the server corresponding to the communication address acquired by the communication address data acquisition unit 142.

  For example, the server operating status acquisition unit 143 acquires the connection status of the front server 1 to the network, the operating status of the OS, the CPU usage rate, the memory usage, and the like. Then, the server operation status acquisition unit 143 determines whether or not each server is operating normally based on the acquired network connection status, OS operating status, CPU usage rate, and memory usage.

  The server activation / determination determining unit 144 obtains, from the server activation / deactivation condition file 135, a constraint condition applied to activation or termination of a target server that performs activation or termination among servers connected to the network. Specify the contents of other servers and conditions specified in. Specifically, the server activation / deactivation determination unit 144 activates or deactivates the target server and the other server based on the activation and deactivation order included in the content of the constraint condition or the dependency relationship between the servers. Decide the order of Further, the server activation / determination determining unit 144 restricts the server to be activated or deactivated after the server whose operational state is determined to be abnormal by the server operational status acquisition unit 143 when it is activated or deactivated in the determined order. It is determined whether the activation or the stop is possible with reference to the process when the control included in the content of the condition fails.

  For example, when the server start / stop control device 100 receives a command to stop the communication network device A from the maintenance person, the server start / stop determination unit 144 causes the front server 1, the front server 2, The constraint conditions relating to each of the DB server 1, the DB server 2, and the log server 1 are read, and the server stop order and the like are determined. Then, when starting or stopping servers in the determined order, the server start / stop determination unit 144 can start or stop subsequent servers if the start or stop fails in any server It is determined whether or not.

  The trigger for starting and stopping the server is not limited to the designation by the maintenance person described above. For example, the operating state of the server is monitored and the starting and stopping of the server are executed based on the operating state. It may be the case. The designation by the maintenance person may be performed by registering the start or stop time in advance.

  The server activation / deactivation request unit 145 executes activation or deactivation of the server after satisfying the conditions specified by the server activation / deactivation determination unit 144. Specifically, the server start / stop request unit 145 executes server start and stop in the order determined by the server start / stop determination unit 144. Further, the server start / stop request unit 145 executes start and stop of the server based on the determination result of whether or not the server start / stop determining unit 144 can start or stop. For example, the server start / stop request unit 145 starts or stops the server by transmitting a start request command or a stop request command to the server on the communication network. The log management unit 146 stores the processing content by the server start / stop control device 100 in the log file 136.

  Next, a processing procedure of the server start / stop control apparatus 100 according to the first embodiment will be described with reference to FIGS. 9A to 9C. FIG. 9A to FIG. 9C are sequence diagrams illustrating a processing procedure performed by the server start / stop control apparatus according to the first embodiment. 9A to 9C show processing procedures by the server activation / deactivation control device 100 in the order of FIGS. 9A, 9B, and 9C. 9A to 9C exemplify a case where a failure occurs in the front server 2 when the communication network apparatus A is stopped. Moreover, below, the process by the server start / stop control apparatus 100 will be described using each unit included in the server start / stop control apparatus 100.

  As shown in FIG. 9A, in the server start / stop control apparatus 100 according to the first embodiment, when a stop execution command of the communication network apparatus A is input from the maintenance person via the graphic user interface 110, the server start / stop The stop determination unit 144 refers to the constraint condition and determines the server to be stopped first as the front server 1 (step S201). The server start / stop control device 100 records in the log file 136 that the request for stop execution has been received before the server start / stop determination unit 144 determines a server to be stopped first, The identifier of the communication network device A is specified from the device data file 131. In the server activation / deactivation control device 100, the identifier of each server is extracted from the server configuration file 132.

  When it is determined that the server to be stopped first is the front server 1, the server operating status acquisition unit 143 checks the connection status to the front server 1 and the operating status of the OS of the front server 1. After obtaining the communication address from the communication address data file, first, the network connection status is confirmed with respect to the front server 1 (step S202).

  When the front server 1 accepts the network connection status confirmation, the front server 1 responds with the network connection status (step S203). When receiving the response of the network connection status from the front server 1, the server operating status acquisition unit 143 checks the process / OS operating status (step S204) and receives the process / OS operating status response (step S205). Then, the server operation status acquisition unit 143 determines whether the front server 1 can be stopped from the acquired state of the front server 1. If the server operation status acquisition unit 143 determines that the server can be stopped (step S206), the server start / stop request unit 145 transmits a process / OS stop request to the front server 1 (step S207).

  When the front server 1 receives the process / OS stop request from the server start / stop request unit 145, the front server 1 returns a process / OS stop response to stop the process and the OS (step S208) and stops the server (step S209). ). When the server start / stop determination unit 144 receives a process / OS stop response from the front server 1, the server start / stop determination unit 144 refers to the constraint condition and determines the server to be stopped next as the front server 2 (step S210). Note that the log management unit 146 records that the front server 1 is normally stopped in the log file 136.

  When it is determined that the server to be stopped next is the front server 2, the server operating status acquisition unit 143 checks the connection status to the front server 2 and the operating status of the OS of the front server 2. After obtaining the communication address from the communication address data file, the network connection status is confirmed with respect to the front server 2 (step S211).

  Here, in the front server 2, as shown in FIG. 9A, since a failure has occurred, when the network connection status confirmation is accepted, a network connection status (error response) is returned (step S212). When receiving the response of the network connection status (error response) from the front server 2, the server operating status acquisition unit 143 determines that the front server 2 cannot be stopped (step S213). Then, the log management unit 146 records in the log file 136 that the front server 2 has not been stopped normally and the operating state of the front server 2.

  Thereafter, the server start / stop determination unit 144 refers to the constraint condition and determines the next server to be stopped as the DB server 1 (step S214). Here, the server start / stop determination unit 144 determines whether or not the DB server 1 can be stopped when the front server 2 cannot be stopped with reference to the constraint condition (step S215). If it is determined that the DB server 1 can be stopped (step S216), the server operating status acquisition unit 143 checks the connection status to the DB server 1 and the operating status of the OS of the DB server 1 to check the DB server 1 After the communication address 1 is acquired from the communication address data file, the network connection status is confirmed with respect to the DB server 1 (step S217).

  Upon receiving the network connection status confirmation, the DB server 1 responds with the network connection status (step S218). When receiving the response of the network connection status from the DB server 1, the server operating status acquisition unit 143 checks the process / OS operating status (step S219) and receives the process / OS operating status response (step S220). Then, the server operation status acquisition unit 143 determines whether the DB server 1 can be stopped from the acquired state of the DB server 1. Here, if the server operation status acquisition unit 143 determines that the server can be stopped (step S221), the server start / stop request unit 145 transmits a process / OS stop request to the DB server 1 (step S222).

  Upon receiving the process / OS stop request from the server start / stop request unit 145, the DB server 1 returns a process / OS stop response indicating that the process and the OS are to be stopped (step S223) and stops the server (step S224). ). When the server start / stop determination unit 144 receives a process / OS stop response from the DB server 1, the server start / stop determination unit 144 refers to the constraint condition and determines the server to be stopped next as the DB server 2. Note that the log management unit 146 records in the log file 136 that the DB server 1 has been normally stopped.

  When it is determined that the server to be stopped next is the DB server 2, the server start / stop determination unit 144 determines whether or not the DB server 2 can be stopped when the front server 2 cannot be stopped with reference to the constraint condition ( Step S225). If it is determined that the DB server 2 can be stopped (step S226), the server operating status acquisition unit 143 checks the connection status to the DB server 2 and the operating status of the OS of the DB server 2 to check the DB status. After obtaining the communication address of the server 2 from the communication address data file, the network connection status is confirmed with respect to the DB server 2 (step S227).

  Upon receiving the network connection status confirmation, the DB server 2 responds with the network connection status (step S228). When receiving the response of the network connection status from the DB server 2, the server operating status acquisition unit 143 checks the process / OS operating status (step S229) and receives the process / OS operating status response (step S230). Then, the server operation status acquisition unit 143 determines whether the DB server 2 can be stopped from the acquired state of the DB server 2. If the server operation status acquisition unit 143 determines that the server can be stopped (step S231), the server start / stop request unit 145 transmits a process / OS stop request to the DB server 2 (step S232).

  When the DB server 2 receives the process / OS stop request from the server start / stop request unit 145, the DB server 2 returns a process / OS stop response to stop the process and the OS (step S233) and stops the server (step S234). ). When the server start / stop determination unit 144 receives a process / OS stop response from the DB server 1, the server start / stop determination unit 144 refers to the constraint condition and determines that the server to be stopped next is the log server 1. Note that the log management unit 146 records in the log file 136 that the DB server 2 has been normally stopped.

  When it is determined that the server to be stopped next is the log server 1, the server start / stop determination unit 144 determines whether or not the log server 1 can be stopped when the front server 2 cannot be stopped with reference to the constraint condition ( Step S235). When it is determined that the log server 1 can be stopped (step S236), the server operation status acquisition unit 143 checks the connection status to the log server 1 and the OS operation status of the log server 1 in order to confirm the log server 1 status. After obtaining the communication address of the server 1 from the communication address data file, the network connection status is confirmed with respect to the log server 1 (step S237).

  When the log server 1 receives the network connection status confirmation, the log server 1 responds with the network connection status (step S238). When receiving the response of the network connection status from the log server 1, the server operating status acquisition unit 143 checks the process / OS operating status (step S239) and receives the process / OS operating status response (step S240). Then, the server operation status acquisition unit 143 determines whether the log server 1 can be stopped from the acquired state of the log server 1. If the server operation status acquisition unit 143 determines that the server can be stopped (step S241), the server start / stop request unit 145 transmits a process / OS stop request to the log server 1 (step S242).

  When the log server 1 receives the process / OS stop request from the server start / stop request unit 145, the log server 1 returns a process / OS stop response to stop the process and the OS (step S243) and stops the server (step S244). ). When the server start / stop determination unit 144 receives a process / OS stop response from the log server 1, the server start / stop determination unit 144 refers to the constraint condition and confirms that there is no server to be stopped next. The log management unit 146 records that the log server 1 is normally stopped in the log file 136.

  Then, the log management unit 146 stores the execution result in the log file (step S245), and the server start / stop control device 100 maintains a response that the stop of the communication network device A is executed via the graphic user interface 110. The user is notified (step S246), and the process is terminated.

  Note that the processing procedure described above is merely an example, and the server start / stop control apparatus 100 according to the first embodiment can execute the same processing even in the stop processing of only a predetermined server.

[Effect of Example 1]
As described above, according to the first embodiment, each server in which roles are assigned is connected to a network for each role, and each server is started or stopped in a system that performs cooperative processing among the servers that are assigned roles. In the server activation / deactivation control apparatus that controls the server, the server activation / deactivation condition file 135 is a restriction condition applied to activation or deactivation of each server, and for each server, a predetermined condition is satisfied when the server is activated or deactivated. Another server to be stored and a constraint condition indicating the contents of the condition are stored. Then, the server activation / determination determining unit 144 acquires, from the server activation / deactivation condition file 135, the restriction condition applied to activation or deactivation of the target server that performs activation or deactivation among the servers connected to the network, Identify the contents of other servers and conditions specified in the constraints. Then, the server start / stop request unit 145 satisfies the conditions specified by the server start / stop determination unit 144 for the other servers specified by the server start / stop determination unit 144, Perform a stop. Therefore, the server activation / deactivation control apparatus 100 according to the first embodiment maintains the communication network even if there is an operation dependency between the types of servers constituting the communication network or a complicated deactivation procedure is required. It is possible for a person to quickly control the start and stop of each server without determining whether or not to stop each server. Further, the server activation / deactivation control apparatus 100 according to the first embodiment can avoid work mistakes because determination by a maintenance person is unnecessary.

  Further, according to the first embodiment, the server activation / deactivation condition file 135 stores, as the contents of the constraint conditions, the sequence of activation and deactivation, the dependency between servers, and the processing when the control fails. Therefore, the server activation / deactivation control apparatus 100 according to the first embodiment is configured so that the maintenance person of the communication network can determine whether or not each server can be stopped even if a complicated stop procedure is required depending on the operation state of each server configuring the communication network. It is possible to quickly control the start and stop of each server without determining the stop procedure.

  Further, according to the first embodiment, the server start / stop determination unit 144 determines the order in which the servers are started or stopped based on the start and stop order included in the contents of the constraint condition or the dependency relationship between the servers. decide. Then, the server start / stop request unit 145 executes server start or stop in the order determined by the server start / stop determination unit 144. Accordingly, the server start / stop control apparatus 100 according to the first embodiment executes server start and stop in the correct order in consideration of the restrictions even when there are restrictions on start or stop between different server types. Is possible.

  Further, according to the first embodiment, the server operation status acquisition unit 143 communicates with each server connected to the network, and determines whether each server is operating normally. Then, when the server start / stop request unit 145 starts or stops the servers in the determined order, the server to be started or stopped after the server whose operating state is determined to be abnormal by the server operating status acquisition unit 143 Control is performed so as to satisfy the processing when the control included in the content of the constraint condition fails. Therefore, the server activation / deactivation control device 100 according to the first embodiment can cope with even if the server operating state is different from the normal state due to a server failure or the like.

  In the first embodiment described above, the stop of the server when the communication network device A is stopped has been described. In the second embodiment, a case where a plurality of communication network devices are connected to a communication network and a disaster recovery solution is employed will be described.

  Here, the disaster recovery solution will be described. Generally, a communication network device is accommodated and operated in one or more data centers. However, when a disaster occurs in the location of the data center and a failure occurs in the accommodated communication network device, the communication network device is also operated. A disaster recovery solution is employed to keep it running. In disaster recovery solutions, communication network devices are accommodated in remote data centers in addition to the primary data center, and even if the primary data center fails due to a disaster, the remote data center The communication network is continuously operated by detouring and consolidating communication paths.

  In this case, when the communication network device is stopped and started in a periodic inspection or the like, the communication network accommodated in either the primary data center or the remote data center in order to keep the communication network operating. The device needs to be up. Therefore, for example, when stopping the communication network device accommodated in the primary data center, it is determined in advance whether the communication network device accommodated in the remote data center is not operating due to a failure or the like. It is necessary to confirm.

  Therefore, in the prior art, when the communication network device is stopped from the server start / stop control device, the following procedure is performed. First, the maintenance person of the communication network device confirms the operating state of the communication network device to be stopped. Next, when the maintenance person stops the communication network device, the operating state of another communication network device that bypasses and aggregates the communication route passing through the communication network device is confirmed. Next, when the other communication network device is operating normally, the maintenance person starts or stops the server from the server stop control device for each server to be stopped.

  As described above, in the related art, when the communication network on the communication network in which the disaster recovery solution is adopted is stopped, it is necessary to confirm the maintenance person at each stage. Therefore, start and stop cannot be controlled quickly, and an operation error may occur. Therefore, in the second embodiment, a server activation / deactivation control device capable of quickly controlling activation and deactivation even when the communication network on the communication network in which the disaster recovery solution is adopted is deactivated will be described.

  FIG. 10 is a schematic diagram illustrating an example of a communication network according to the second embodiment. For example, as shown in FIG. 10, a communication network apparatus A, a communication network apparatus B, a communication network apparatus C, and a server activation / deactivation control apparatus 100a are connected to the communication network according to the second embodiment. As shown in FIG. 10, each of the communication network devices A to C includes two front servers, two DB servers, and one log server. In the communication network shown in FIG. 10, the communication network device C is set as the first detour of the communication network device A, and the communication network device B is set as the second detour.

  First, the configuration of the server start / stop control device 100a according to the second embodiment will be described. FIG. 11 is a diagram illustrating an example of the configuration of the server start / stop control apparatus 100a according to the second embodiment. The server start / stop control device 100a according to the second embodiment is different from the server start / stop control device 100 according to the first embodiment in that it includes a communication network device operation data file 137, a communication network device priority data file 138, and a communication network. The point which newly has the apparatus priority identification part 147, and the processing content of the server operating condition acquisition part 143a and the server start / stop determination part 144a differ. Hereinafter, these will be mainly described.

  The communication network device priority data file 138 stores the priority for operating the communication network device. FIG. 12 is a diagram illustrating an example of information stored in the communication network device priority data file 138 according to the second embodiment. For example, the communication network device priority data file 138 stores “priority: communication network device A> communication network device B> communication network device C” as shown in FIG. Here, in the above information, the priority for operating the communication network device A is higher than that of the communication network device B and the communication network device C, and the priority for operating the communication network device B is higher than that of the communication network device C. It shows that.

  The communication network device operation data file 137 stores information related to the communication path of the communication network. Specifically, the communication network device operation data file 137 stores information on communication paths that are detoured and aggregated when the communication network device on the communication network is stopped. FIG. 13 is a diagram illustrating an example of information stored in the communication network device operation data file 137 according to the second embodiment. For example, as shown in FIG. 13, the communication network device operation data file 137 stores information in which “stop: communication network device A” is associated with “detour / aggregate communication route: communication network device C”. Here, the above-described information indicates that the detour / aggregation route when “communication network device A” is stopped is “communication network device C”.

  The communication network device data file 131 stores an identifier for uniquely specifying the communication network device A, the communication network device B, and the communication network device C. In addition, the server configuration file 132 stores an identifier for uniquely identifying a server that configures each of the communication network device A, the communication network device B, and the communication network device C. Further, the communication address data file 133 stores the communication address of the server that configures each of the communication network device A, the communication network device B, and the communication network device C. The communication network device start / stop file 134 stores information indicating that the servers constituting the communication network device A are stopped in the order of the front server 11, the front server 12, the DB server 11, the DB server 12, and the log server 11. To do.

  The server operating status acquisition unit 143a acquires, for each communication network device connected to the communication network, the operating status of the server constituting the communication network device, and determines the operating status of the communication network device from the acquired operating status of the server. To do.

  The server activation / determination determining unit 144a specifies a detour / aggregate communication path for stopping a predetermined communication network apparatus based on the detour / aggregate communication path information stored in the communication network apparatus operation data file 137. Further, the server start / stop determination unit 144a determines a stop order when stopping a predetermined communication network device based on the stop order stored in the communication network device start / stop file.

  The communication network device priority identifying unit 147 identifies the priority of the communication network device operated on the communication network based on the priority information stored by the communication network device priority data file 138.

  Next, a processing procedure of the server start / stop control apparatus 100a according to the second embodiment will be described with reference to FIGS. 14A to 14F. FIG. 14A to FIG. 14F are sequence diagrams illustrating a processing procedure performed by the server start / stop control device 100a according to the second embodiment. 14A to 14F show processing procedures by the server activation / deactivation control device 100a in the order of FIGS. 14A, 14B, 14C, 14D, 14E, and 14F. 14A to 14F, when a request to stop the communication network devices A and B is received from the maintenance person, a failure has occurred in the front server 31 of the communication network device C, and the communication network device C As an example, it is impossible to bypass or aggregate the communication paths. In the following, processing by the server start / stop control device 100a will be described using each unit of the server start / stop control device 100a.

  As shown in FIG. 14A, in the server start / stop control device 100a according to the second embodiment, the communication network device A and the communication network device B are stopped by the maintenance person from the graphic user interface 110 in order to stop the operation. When requesting stop execution of the device A and the communication network device B, the log management unit 146 records in the log file that the stop execution request has been received.

  Then, the server start / stop determination unit 144 refers to the constraint condition and determines the server to be stopped first in the communication network device A as the front server 11 (step S301). In the server start / stop control device 100a, the identifier of the communication network device A is specified from the communication network device data file 131 before the server start / stop determination unit 144a determines the server to be stopped first. In the server activation / deactivation control device 100a, the identifier of each server is extracted from the server configuration file 132.

  When it is determined that the server to be stopped first is the front server 11, the server operating status acquisition unit 143 a checks the connection status to the front server 11 and the operating status of the OS of the front server 11. After acquiring the communication address from the communication address data file 133, first, the network connection status is confirmed with respect to the front server 11 (step S302).

  When the front server 11 accepts the network connection status confirmation, the front server 11 responds with the network connection status (step S303). When receiving the response of the network connection status from the front server 11, the server operating status acquisition unit 143a checks the process / OS operating status (step S304) and receives the process / OS operating status response (step S305). Then, the server operation status acquisition unit 143a determines whether or not the front server 11 is operating normally from the acquired state of the front server 11.

  Here, if it is determined that the front server 11 is operating normally (step S306), the server start / stop determination unit 144a refers to the constraint condition and determines the server to be stopped next as the front server 12 ( Step S307). Note that the log management unit 146 records that the front server 11 is normally stopped in the log file 136.

  When it is determined that the server to be stopped next is the front server 12, the server operating status acquisition unit 143 a checks the connection status to the front server 12 and the operating status of the OS of the front server 12. After acquiring the communication address from the communication address data file 133, first, the network connection status is confirmed with respect to the front server 12 (step S308).

  When the front server 12 receives the network connection status confirmation, the front server 12 responds with the network connection status (step S309). When receiving the response of the network connection status from the front server 12, the server operating status acquisition unit 143a checks the process / OS operating status (step S310) and receives the process / OS operating status response (step S311). Then, the server operation status acquisition unit 143a determines whether or not the front server 12 is operating normally from the acquired state of the front server 12.

  Here, if it is determined that the front server 12 is operating normally (step S312), the server activation / determination determining unit 144a refers to the constraint condition and determines the next server to be stopped as the DB server 11 ( Step S313). The log management unit 146 records that the front server 12 has been normally stopped in the log file 136.

  When it is determined that the server to be stopped next is the DB server 11, the server operation status acquisition unit 143 a checks the connection status to the DB server 11, the OS operation status of the DB server 11, and the like. After acquiring the communication address from the communication address data file 133, first, the network connection status is confirmed with respect to the DB server 11 (step S314).

  Upon receiving the network connection status confirmation, the DB server 11 responds with the network connection status (step S315). When receiving the response of the network connection status from the DB server 11, the server operating status acquisition unit 143a checks the process / OS operating status (step S316) and receives the process / OS operating status response (step S317). Then, the server operation status acquisition unit 143a determines whether the DB server 11 is operating normally from the acquired state of the DB server 11.

  If it is determined that the DB server 11 is operating normally (step S318), the server start / stop determination unit 144a refers to the constraint condition and determines the server to be stopped next as the DB server 12 ( Step S319). The log management unit 146 records that the DB server 11 has been normally stopped in the log file 136.

  When it is determined that the server to be stopped next is the DB server 12, the server operation status acquisition unit 143 a determines the connection status to the DB server 12 and the OS operation status of the DB server 12. After obtaining the communication address from the communication address data file 133, first, the network connection status is confirmed with respect to the DB server 12 (step S320).

  When receiving the network connection status confirmation, the DB server 12 responds with the network connection status (step S321). When receiving the response of the network connection status from the DB server 12, the server operating status acquisition unit 143a checks the process / OS operating status (step S322) and receives the process / OS operating status response (step S323). Then, the server operation status acquisition unit 143a determines whether the DB server 12 is operating normally from the acquired state of the DB server 12.

  Here, if it is determined that the DB server 12 is operating normally (step S324), the server start / stop determination unit 144a refers to the constraint condition and determines the server to be stopped next as the log server 11 ( Step S325). The log management unit 146 records that the DB server 12 has been normally stopped in the log file 136.

  When it is determined that the server to be stopped next is the log server 11, the server operation status acquisition unit 143 a checks the connection status to the log server 11 and the OS operation status of the log server 11. After acquiring the communication address from the communication address data file 133, first, the network connection status is confirmed with respect to the log server 11 (step S326).

  When the log server 11 receives the network connection status confirmation, the log server 11 responds with the network connection status (step S327). When receiving the response of the network connection status from the log server 11, the server operating status acquisition unit 143a checks the process / OS operating status (step S328) and receives the process / OS operating status response (step S329). Then, the server operation status acquisition unit 143a determines whether the log server 11 is operating normally from the acquired state of the log server 11.

  Here, if it is determined that the log server 11 is operating normally (step S330), the server start / stop determination unit 144a communicates because all the servers constituting the communication network device A are operating normally. It is determined that the network device A is operating normally (step S331).

  Subsequently, the server start / stop determination unit 144 refers to the constraint condition and determines the server to be stopped first in the communication network device B as the front server 21 (step S332). In the server start / stop control device 100a, the identifier of the communication network device B is specified from the communication network device data file 131 before the server to be stopped first is determined by the server start / stop determination unit 144a. In the server activation / deactivation control device 100a, the identifier of each server is extracted from the server configuration file 132.

  When the server start / stop control device 100a according to the second embodiment determines that the server to be stopped first in the communication network device B is the front server 21, the server start / stop control device 100a checks the connection state to the front server 21 and the operating state of the OS of the front server 21. Then, the connection state and the operating state of the OS are confirmed in the order of the front server 22, the DB server 21, the DB server 22, and the log server 21 (steps S333 to S361). Since Steps S333 to S361 are the same as Steps S302 to 330 described above, detailed description thereof is omitted.

Then, the server start / stop determination unit 144a determines that the communication network device B is operating normally because all the servers constituting the communication network device B are operating normally (step S362).

  Subsequently, the server activation / determination determining unit 144a refers to the constraint condition and determines that the server to be first stopped in the communication network device C is the front server 31 (step S363). In the server start / stop control device 100a, the identifier of the communication network device C is specified from the communication network device data file 131 before the server start / stop determination unit 144a determines the server to be stopped first. In the server activation / deactivation control device 100a, the identifier of each server is extracted from the server configuration file 132.

  When the front server 31 receives the network connection status confirmation (step S364), the front server 31 responds with the network connection status (step S365). When receiving the response of the network connection status from the front server 31, the server operating status acquisition unit 143a checks the process / OS operating status (step S366) and receives the process / OS operating status response (step S367). Here, the front server 31 transmits a response indicating that a failure has occurred to the server activation / deactivation control device 100a.

  The server operating status acquisition unit 143a determines from the acquired state of the front server 31 that the operating state of the OS is different from the normal state, and determines that the communication network device C is in an abnormal state (step S368). The log management unit 146 records that the operation of the front server 31 is abnormal in the log file 136.

  Then, the server start / stop determination unit 144a determines that detouring and aggregation of the communication path to the communication network device C is impossible because the front server 31 configuring the communication network device C is in a state different from normal. . When the server start / stop determination unit 144a stops the communication network device A and the communication network device B, there is no communication network device that bypasses and aggregates the communication paths to the communication network device A and the communication network device B. Therefore, it is determined that it is impossible to stop both the communication network device A and the communication network device B.

  In response to the determination result described above, the communication network device priority identifying unit 147 refers to the priority data stored in the communication network device priority data file 138 and the communication network device A is more than the communication network device B. It is determined that the priority for operation is high, and it is determined that the communication network device A cannot be stopped and the communication network device B can be stopped (step S369).

  Then, the server start / stop determination unit 144a specifies that the server to be stopped first is the front server 21 from the communication network device start / stop file 134 and the acquired state of each server of the communication network device B. (Step S370). When it is specified that the server to be stopped first is the front server 21, the server start / stop request unit 145 transmits a process / OS stop request to the front server 21 (step S371).

  When the front server 21 receives the process / OS stop request from the server start / stop request unit 145, the front server 21 returns a process / OS stop response to stop the process and the OS (step S372) and stops the server (step S373). ). Upon receiving a process / OS stop response from the front server 21, the server start / stop determination unit 144a refers to the constraint condition and determines the next server to be stopped as the front server 22 (step S374). Note that the log management unit 146 records that the front server 21 is normally stopped in the log file 136.

  When it is determined that the next server to be stopped is the front server 22, the server start / stop request unit 145 transmits a process / OS stop request to the front server 22 (step S375).

  When the front server 22 receives the process / OS stop request from the server start / stop request unit 145, the front server 22 returns a process / OS stop response to stop the process and the OS (step S376) and stops the server (step S377). ). When receiving the process / OS stop response from the front server 22, the server start / stop determination unit 144a refers to the constraint condition and determines the server to be stopped next as the DB server 21 (step S378). Note that the log management unit 146 records that the front server 22 is normally stopped in the log file 136.

  When it is determined that the server to be stopped next is the DB server 21, the server start / stop request unit 145 transmits a process / OS stop request to the DB server 21 (step S379).

  Upon receiving the process / OS stop request from the server start / stop request unit 145, the DB server 21 returns a process / OS stop response indicating that the process and the OS are to be stopped (step S380) and stops the server (step S381). ). Upon receiving a process / OS stop response from the DB server 21, the server start / stop determination unit 144a refers to the constraint condition and determines the server to be stopped next as the DB server 22 (step S382). Note that the log management unit 146 records in the log file 136 that the DB server 21 has been normally stopped.

  When it is determined that the server to be stopped next is the DB server 22, the server start / stop request unit 145 transmits a process / OS stop request to the DB server 22 (step S383).

  When the DB server 22 receives the process / OS stop request from the server start / stop request unit 145, the DB server 22 returns a process / OS stop response to stop the process and the OS (step S384) and stops the server (step S385). ). When receiving the process / OS stop response from the DB server 22, the server start / stop determination unit 144a refers to the constraint condition and determines the server to be stopped next as the log server 21 (step S386). Note that the log management unit 146 records in the log file 136 that the DB server 21 has been normally stopped.

  When it is determined that the server to be stopped next is the log server 21, the server start / stop request unit 145 transmits a process / OS stop request to the log server 21 (step S387).

  When the log server 21 receives the process / OS stop request from the server start / stop request unit 145, the log server 21 returns a process / OS stop response to stop the process and the OS (step S388) and stops the server (step S389). ). When receiving the process / OS stop response from the log server 21, the server start / stop determination unit 144a refers to the constraint condition and confirms that there is no server to be stopped next. The log management unit 146 records in the log file 136 that the log server 21 has been normally stopped.

Then, the log management unit 146 stores the execution result in the log file (step S390), and the server start / stop control device 100a executes the stop of the communication network device B and the stop of the communication network device A. A response indicating that it has not been executed is notified to the maintenance person via the graphic user interface 110 (step S391) , and the process is terminated.

  Note that the above-described processing procedure is merely an example, and the server activation / deactivation control apparatus 100a according to the second embodiment can perform the same process in the activation process of the communication network apparatus.

[Effect of Example 2]
As described above, according to the second embodiment, when a plurality of communication network devices are configured by a plurality of servers and the activation or the stop of the communication network device is controlled, the server activation / deactivation determination unit 144a A server start / stop condition file that specifies a communication network device to be started or stopped based on a preset priority for operation for each server, and a restriction condition applied to start or stop of a server constituting the specified communication network device 135, and the contents of other servers and conditions specified in the constraint conditions are specified.

  For example, as described above, the server start / stop control device 110a acquires the operating status of the communication network device A, the communication network device B, and the communication network device C when stopping the communication network device A and the communication network device B. Therefore, it is determined that the front server 31 configuring the communication network device C is in a state different from the normal state, and the stop of the communication network device A cannot be executed based on the priority recorded in the communication network device priority data file. And the server constituting the communication network apparatus B is only stopped. Therefore, the server activation / deactivation control device 110a according to the second embodiment does not require the maintenance person to check the operation status of the communication network device and the communication network device that can be stopped, and therefore, the time for stopping the communication network device is reduced. It is possible to reduce and avoid an operation error of a maintenance person of the communication network device.

  In the above-described first and second embodiments, the case where the server is stopped has been described. In the third embodiment, a case where a server is started will be described. FIG. 15 is a schematic diagram illustrating an example of a communication network according to the third embodiment. For example, as shown in FIG. 15, the communication network apparatus A and the server activation / deactivation control apparatus 100b are connected to the communication network according to the third embodiment. Note that the communication network apparatus A shown in FIG. 15 is the same as the communication network apparatus A shown in FIG. As illustrated in FIG. 15, the server activation / deactivation control device 100b according to the third embodiment sequentially activates the stopped server group after satisfying the restrictions on activation.

  First, the configuration of the server start / stop control device 100b according to the third embodiment will be described. FIG. 16 is a diagram illustrating an example of the configuration of the server start / stop control apparatus 100b according to the third embodiment. The server activation / deactivation control device 100b according to the third embodiment stores information stored in the communication network device activation / deactivation file 134a and the server activation / deactivation condition file 135a as compared to the server activation / deactivation control device 100 according to the first embodiment. And the processing contents by the server start / stop determination unit 144b are different. Hereinafter, these will be mainly described.

  The communication network device start / stop file 134a stores the server start order and stop order for each communication network device connected to the communication network. FIG. 17 is a diagram illustrating an example of information stored in the communication network device activation / deactivation file 134a according to the third embodiment.

  For example, the communication network device activation stop file 134a stores the activation sequence of servers for each communication network device, as shown in FIG. As an example, the communication network device activation / deactivation file 134 is associated with “communication network: A”, “1: log server 1, 2: DB server 2, 3: DB server 1, 4: front server 2,” 5: “Front server 1” is stored. Here, the above-described information means that, in the network apparatus A, the log server 1, the DB server 2, the DB server 1, the front server 2, and the front server 1 are started in this order.

  Returning to FIG. 16, the server start / stop condition file 135a is a restriction condition applied to starting or stopping each server, and for each server, another server that satisfies a predetermined condition when starting or stopping the server. And a constraint condition indicating the contents of the condition is stored. FIG. 18 is a diagram illustrating an example of information stored in the server start / stop condition file 135a according to the third embodiment.

For example, the server start / stop condition file 135a stores, for each server, restrictions for starting the server, as shown in FIG. For example, the server start / stop condition file 135a according to the third embodiment stores “unstartable after failing to start the DB server 1 or DB server 2” in association with “front server 1”. Here, the above-mentioned information means that the front server 1 cannot be started when the DB server 1 or the DB server 2 fails to start. Note that the information shown in FIG. 18 is merely an example.

  The server activation / deactivation determination unit 144b acquires, from the server activation / deactivation condition file 135a, restriction conditions that apply to activation or deactivation of the target server that performs activation or deactivation among the servers connected to the network. Specify the contents of other servers and conditions specified in.

  For example, when the server start / stop control device 100b receives a command to start the communication network device A from the maintenance person, the server start / stop determination unit 144b causes the front server 1, the front server 2, and the like constituting the communication network device A, The constraint conditions related to the DB server 1, the DB server 2, and the log server 1 are read, and the server startup order and the like are determined. Then, the server activation / determination determining unit 144b determines whether the subsequent servers can be activated if the activation fails in any of the servers when performing the activation of the servers in the determined order. To do.

  Next, a processing procedure of the server start / stop control apparatus 100b according to the third embodiment will be described with reference to FIGS. 19A to 19C. FIG. 19A to FIG. 19C are sequence diagrams illustrating a processing procedure performed by the server start / stop control device 100b according to the third embodiment. 19A to 19C show processing procedures by the server activation / deactivation control device 100b in the order of FIGS. 19A, 19B, and 19C. In FIG. 19A to FIG. 19C, when the communication network device A is activated, a failure occurs in the front server 2, so that the process of the front server 2 fails to be activated and cannot be activated in a normal procedure. Take the case as an example. Moreover, below, the process by the server start / stop control device 100b will be described using each unit of the server start / stop control device 100b.

  As shown in FIG. 19A, in the server start / stop control device 100b according to the third embodiment, when a start command for starting the communication network device A is input from the maintenance person via the graphic user interface 110, the server start / stop The stop determination unit 144b refers to the constraint condition and determines that the server to be started first is the log server 1 (step S401). In the server activation / deactivation control device 100b, the server activation / determination determining unit 144b records in the log file 136 that the request to execute activation is received before the server to be activated first is determined, and the communication network The identifier of the communication network device A is specified from the device data file 131. In the server activation / deactivation control device 100b, the identifier of each server is extracted from the server configuration file 132.

  When it is determined that the server to be activated first is the log server 1, the server operation status acquisition unit 143 acquires the communication address of the log server 1 from the communication address data file in order to check the connection state of the log server 1. The network connection status is confirmed with respect to the log server 1 (step S402).

  Upon receiving the network connection status confirmation, the log server 1 responds with the network connection status (step S403). When the server operating status acquisition unit 143 receives a response of the network connection status from the log server 1, the server operating status acquisition unit 143 determines whether or not the log server 1 can be activated from the response content. When it is determined that the server operation status acquisition unit 143 can be started (step S404), the server start / stop request unit 145 logs a process / OS start request that is a request to start a process or OS. It transmits to the server 1 (step S405).

  When the log server 1 receives the process / OS activation request from the server activation / deactivation request unit 145, the log server 1 returns a process / OS activation response to activate the process and the OS (step S406), and activates the server (step S407). ). When the server start / stop determination unit 144b receives the process / OS start response from the log server 1, the server start / stop determination unit 144b refers to the constraint condition and determines the server to be stopped next as the DB server 2 (step S408). The log management unit 146 records in the log file 136 that the log server 1 has been normally activated.

  When it is determined that the server to be started next is the DB server 2, the server operation status acquisition unit 143 acquires the communication address of the DB server 2 from the communication address data file in order to check the connection state of the DB server 2. Then, the network connection status is confirmed with respect to the DB server 2 (step S409).

  When receiving the network connection status confirmation, the DB server 2 responds with the network connection status (step S410). When the server operation status acquisition unit 143 receives a response of the network connection status from the DB server 2, the server operation status acquisition unit 143 determines whether the DB server 2 can be activated from the response content. If it is determined that the server operation status acquisition unit 143 can be started (step S411), the server start / stop request unit 145 sends a process / OS start request, which is a request to execute the process or OS start, to the DB. It transmits to the server 2 (step S412).

  Upon receiving the process / OS start request from the server start / stop request unit 145, the DB server 2 returns a process / OS start response indicating that the process and the OS are to be started (step S413), and starts the server (step S414). ). When the server start / stop determination unit 144b receives the process / OS start response from the DB server 2, the server start / stop determination unit 144b refers to the constraint condition and determines the server to be stopped next as the DB server 1 (step S415). The log management unit 146 records that the DB server 2 has been normally activated in the log file 136.

  When it is determined that the server to be activated next is the DB server 1, the server operation status acquisition unit 143 acquires the communication address of the DB server 1 from the communication address data file in order to check the connection state of the DB server 1. Then, the network connection status is confirmed with respect to the DB server 1 (step S416).

  Upon receiving the network connection status confirmation, the DB server 1 responds with the network connection status (step S417). When receiving the response of the network connection status from the DB server 1, the server operating status acquisition unit 143 determines whether the DB server 1 can be activated from the response content. If it is determined that the server operation status acquisition unit 143 can be started (step S418), the server start / stop request unit 145 sends a process / OS start request, which is a request for executing a process or OS start, to the DB. It transmits to the server 1 (step S419).

  Upon receiving the process / OS activation request from the server activation / deactivation request unit 145, the DB server 1 returns a process / OS activation response to activate the process and OS (step S420) and activates the server (step S421). ). When the server start / stop determination unit 144b receives the process / OS start response from the DB server 1, the server start / stop determination unit 144b refers to the constraint condition and determines the server to be stopped next as the front server 2 (step S422). The log management unit 146 records that the DB server 1 has been normally activated in the log file 136.

  When it is determined that the next server to be activated is the front server 2, the server operation status acquisition unit 143 acquires the communication address of the front server 2 from the communication address data file in order to check the connection state of the front server 2. Then, the network connection status is confirmed with respect to the front server 2 (step S423).

  When the front server 2 accepts the network connection status confirmation, the front server 2 responds with the network connection status (step S424). When the server operating status acquisition unit 143 receives a response of the network connection status from the front server 2, the server operating status acquisition unit 143 determines whether or not the front server 2 can be activated from the response content. When it is determined that the server operation status acquisition unit 143 can be started (step S425), the server start / stop request unit 145 receives a process / OS start request, which is a request for starting the process or the OS. It transmits to the server 2 (step S426).

Here, the front server 2 returns an error response indicating that the process and the OS could not be started normally due to a failure to the server start / stop control device 100b (step S427). It determines that the server start / stop determination unit 144b, when the front server 2 receives the process / OS start response (error response), it is necessary restoration work maintenance person for launch fails (step S428). Then, the server start / stop determination unit 144b refers to the constraint conditions and determines the next server to be stopped as the front server 1 (step S429). Note that the failure of starting the front server 2 is recorded in the log file 136 by the log management unit 146.

  When it is determined that the next server to be started is the front server 1, the server start / stop determination unit 144b refers to the constraints stored in the server start / stop condition file 135a, and the front server when the front server 2 fails to start 1 is determined whether to be activated (step S430). Here, if it is determined that the front server 1 can be started (step S431), the server operation status acquisition unit 143 uses the communication address of the front server 1 as the communication address in order to confirm the connection state of the front server 1. After obtaining from the data file, the network connection status is confirmed with respect to the front server 1 (step S432).

  When the front server 1 accepts the network connection status confirmation, the front server 1 responds with the network connection status (step S433). When the server operating status acquisition unit 143 receives a response of the network connection status from the front server 1, the server operating status acquisition unit 143 determines whether or not the front server 1 can be activated from the response content. When it is determined that the server operation status acquisition unit 143 can be started (step S434), the server start / stop request unit 145 receives a process / OS start request, which is a request for starting the process or the OS. It transmits to the server 1 (step S435).

  When the front server 1 receives the process / OS start request from the server start / stop request unit 145, the front server 1 returns a process / OS start response to start the process and the OS (step S436) and starts the server (step S437). ). When the server start / stop determination unit 144b receives the process / OS start response from the front server 1, the server start / stop determination unit 144b refers to the constraint condition and confirms that there is no server to be started next. The log management unit 146 records that the front server 1 has been normally activated in the log file 136.

  Then, the log management unit 146 stores the execution result in the log file (step S438), and the server start / stop control device 100b maintains the response that the start of the communication network device A is executed via the graphic user interface 110. The user is notified (step S439), and the process is terminated.
