  Exemplary embodiments of a server configuration control device and a server configuration control method of the present application will be described below in detail with reference to the accompanying drawings. The server configuration control device and the server configuration 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 configuration control device of the present application is described. In the first embodiment, a case will be described in which the operation of a server is controlled according to the processing load amounts of a plurality of servers arranged on a communication network.

  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 configuration control device controls the configuration of servers that are operated on the communication network by controlling the operation of each server on the communication network shown in FIG. FIG. 2 is a schematic diagram for explaining an example of processing of the server configuration control device according to the related art. FIG. 2 shows a case where the communication network device has two front servers, one DB server, and one log server, and the two front servers perform the same processing. In FIG. 2, only one communication network device is shown, but actually, a plurality of communication network devices are connected to the communication network.

  The server configuration control device monitors the processing load amount of each server and controls the operation of each server. For example, as shown in FIG. 2, the server configuration control device starts the stopped front server 2 when the front server 1, the DB server, and the log server are started and the processing load on the front server 1 is high. To distribute the load. 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 configuration control apparatus 200 according to the related art. As shown in FIG. 3, the server configuration 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. , Operation state management file 234, server resource threshold management file 235, log file 236, communication network device / server identification unit 241, communication address data acquisition unit 242, server operation status acquisition unit 243, server resource calculation / Relocation unit 244, server start / stop request unit 245, and log management unit 246.

  The graphic user interface 210 is an interface that allows a maintenance person of the server configuration control apparatus 200 to display an operation target and a selection item with icons and menus on a screen and operate them with a pointing device such as a mouse.

  The main processing unit 220 performs overall control of processing by the server configuration 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 information for uniquely identifying servers that configure a plurality of communication network devices arranged on the communication network. For example, the server configuration file 232 stores an identifier for uniquely identifying the front server 1, the front server 2, the DB server, and the log server. The communication address data file 233 stores a communication address for each server constituting the communication network device.

  The operating state management file 234 stores a start request command for starting the server and a stop request command for stopping the server for each server constituting the communication network device. The server resource threshold management file 235 stores a processing load amount threshold. Specifically, the server resource threshold management file 235 stores a threshold for determining whether the server is in a high load state or whether the server is in a low load state.

  The log file 236 stores the processing content executed by the server configuration control apparatus 200. Specifically, the log file 236 stores the processing contents of the server configuration control apparatus 200 stored by the log management unit 246 described later.

  Various information stored by the communication network device data file 231, the server configuration file 232, the communication address data file 233, the operation state management file 234, and the server resource threshold management file 235 are registered in advance by a maintenance person.

  The communication network device / server identification unit 241 identifies the communication network device connected to the communication network based on the information stored in the communication network device data file 231. In addition, the communication network device / server identification unit 241 identifies the servers constituting the communication network device based on the information stored in the server configuration file 232. For example, the communication network device / server identification unit 241 identifies the front server 1, the front server 2, the DB server, and the log server.

  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. The server operation status acquisition unit 243 acquires the operation state from the server corresponding to the communication address acquired by the communication address data acquisition unit 242. For example, the server operation status acquisition unit 243 acquires the processing load amount of the front server 1.

  The server resource calculation / relocation unit 244 refers to the threshold stored by the server resource threshold management file 235 and determines the current operating state of the server acquired by the server operating status acquisition unit 243. For example, the server resource calculation / relocation unit 244 refers to the threshold stored by the server resource threshold management file 235 and the processing load amount of the front server 1 acquired by the server operation status acquisition unit 243 is high. It is determined whether or not there is a low load state. Then, the server resource calculation / relocation unit 244 calculates the number of servers to be started or stopped.

  The server start / stop request unit 245 transmits a start request command or a stop request command to the server on the communication network based on the determination result by the server resource calculation / relocation unit 244. The log management unit 246 stores the processing content by the server configuration control device in the log file 236.

  Under this configuration, the server configuration control apparatus 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 configuration control apparatus 200 according to the related art. FIG. 4 shows the processing after reaching the time to acquire the processing load of the server constituting the communication network device. Note that the time for acquiring the processing load amount of the server can be arbitrarily set by the maintenance person. In addition, the maintenance person may input a request to acquire the processing load amount of the server from the graphic user interface 210.

  As shown in FIG. 4, in the server configuration control apparatus 200 according to the prior art, when the time to acquire the processing load amount of the server is reached, the server operation status acquisition unit 243 displays the front server 1 that is currently operating, A processing load acquisition request for the DB server and log server is transmitted (step S101). When the front server 1, the DB server, and the log server receive the acquisition request from the server configuration control device, they respectively respond to the processing load amount (Step S102, Step S103, Step S104).

  Subsequently, in the server configuration control apparatus 200, when a response of the processing load amount is received from each server, the server resource calculation / relocation unit 244 compares the threshold value registered in advance with the received response, and the front server 1 is determined to be in a high load state (step S105), and the number of servers of the same type to be newly activated is calculated (step S106). Then, the server start / stop request unit 245 transmits a start request command to the front server 2 (step S107).

  When the front server 2 receives the activation request command from the server configuration control apparatus 200, the front server 2 transmits an activation request response, which is a response to the reception, to the server configuration control apparatus 200 (step S108), and activates the server (step S109). . Thereafter, the server configuration control apparatus 200 determines whether or not the processing load amount acquisition timing has been reached (step S110).

  Here, when the acquisition time of the processing load amount has been reached (Yes in step S110), the server operation status acquisition unit 243 determines that the front server 1, the front server 2, the DB server, and the log server that are currently operating. A processing load amount acquisition request is transmitted (step S111). When the front server 1, the front server 2, the DB server, and the log server receive the acquisition request from the server configuration control device, they respectively respond to the processing load amount (step S112, step S113, step S114, step S115).

  Subsequently, in the server configuration control apparatus 200, when a response of the processing load amount is received from each server, the server resource calculation / relocation unit 244 compares the threshold value registered in advance with the received response, and the front server 1 and the front server 2 are determined to be in a low load state (step S116), and the number of servers of the same type to be stopped is calculated (step S117). Then, the server start / stop request unit 245 transmits a stop request command to the front server 2 (step S118).

  When the front server 2 receives the stop request command from the server configuration control device 200, the front server 2 transmits a stop request response, which is a response indicating that it has been received, to the server configuration control device 200 (step S119), and stops the server (step S120). . In the prior art, after the server is started and stopped in step S109 and step S120, the maintenance engineer performs confirmation work, and when the server is not operating normally, the cause is investigated. The maintenance person restarts or stops the server.

  As described above, in the server configuration control device in the prior art, the processing load amount of a plurality of servers is monitored, and when the processing load amount exceeds a threshold, the same type of server is started or stopped. By doing so, the processing load is controlled to be optimized. Here, in the above-described conventional technology, when there is a restriction on operation between different server types, the server cannot be started or stopped.

  In other words, since the conventional server configuration control device only starts or stops the same type of server based on the processing load amount of the server, when there is a restriction on operation between different server types, Considering this, the server cannot be started or stopped. 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 configuration 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 configuration 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 configuration control apparatus, these servers cannot be stopped. That is, in a conventional server configuration control device, when 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 configuration control device cannot perform such processing and cannot stop the log server.

  As described above, in the conventional server configuration control apparatus, there is a start or stop order between different server types, processing after a control failure is limited, or there is a dependency relationship between server operations. When there are such restrictions, it is not possible 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 processing load amount cannot be quickly optimized.

  Therefore, the server configuration control device of the present application enables to quickly control the processing load amount and the power consumption amount even when there are restrictions when starting or stopping between different server types. With the goal. In the first embodiment, as described above, a case where the processing load amount is controlled will be described.

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

  As shown in FIG. 5, the communication network apparatus A has a subset A1 and a subset A2, and executes processing in response to a request from a client apparatus (not shown). Specifically, when the communication network apparatus A executes arbitrary processing, the subset A1 and the subset A2 perform processing in parallel. That is, the communication network device A executes parallel distributed processing to distribute the load related to the processing.

  As shown in FIG. 5, the subset A <b> 1 includes a front server 1, a front server 2, and a log server 1. The subset A2 includes a front server 3 and a log server 2 as shown in FIG.

  In the subset A1, for example, as shown in FIG. 5, the front server 1 acquires network information and user information from the DB server 1, executes processing according to the processing request, and logs a log indicating the processing content to the log server Send to 1. Further, as shown in FIG. 5, the front server 2 acquires network information and user information from the DB server 2, 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 and the front server 3. 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. Specifically, 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 as shown in FIG.

  In the subset A2, for example, as shown in FIG. 5, the front server 3 acquires network information and user information from the DB server 2, executes processing according to the processing request, and sends a log to the log server 2. . The log server 2 stores the processing contents of the communication network device A. Specifically, the log server 2 stores the log received from the front server 3 as shown in FIG.

  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 configuration control device monitors the processing load amount of each server and quickly controls the processing load amount and power consumption even when there are restrictions when starting or stopping between different server types. To do. FIG. 6 is a diagram illustrating an example of the configuration of the server configuration control apparatus 100 according to the first embodiment.

  As illustrated in FIG. 6, the server configuration 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. An operation state management file 134, a communication network device start / stop file 135, a priority data file 136, a start / stop condition management file 137, a log file 138, a communication network device / server identification unit 141, The communication address data acquisition unit 142, the server operation status acquisition unit 143, the server activation / deactivation determination unit 144, the server activation / deactivation request unit 145, and the log management unit 146 are included.

  The graphic user interface 110 is an interface that allows a maintenance person of the server configuration control apparatus 100 to display an operation target and selection items with icons and menus on a screen and operate them with a pointing device such as a mouse.

  The main processing unit 120 performs overall control of processing by the server configuration control apparatus 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 information for uniquely specifying a server that configures a communication network device arranged on the communication network. For example, the server configuration file 132 stores identifiers for uniquely specifying the front servers 1 to 3, the DB servers 1 to 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 operation state management file 133 is a connection state of each server acquired by a server operation state acquisition unit 143 to be described later, an operating state of an OS (Operation System), a CPU usage rate and a memory usage amount of each server, and the like. Remember.

  The communication network device start / stop file 135 stores a server start order and a 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 start / stop file 135 according to the first embodiment.

  For example, the communication network device start / stop file 135 stores the stop order of servers for each subset of communication network devices, as shown in FIG. As an example, the communication network device activation / deactivation file 135 is associated with “communication network: A, subset: A1”, “1: front server 1, 2: front server 2, 3: DB server 1, 4”. : DB server 2, 5: log server 1 ". Here, the above information means that in the subset A1 of the network device A, the front server 1, the front server 2, the DB server 1, the DB server 2, and the log server 1 are stopped in this order.

  Returning to FIG. 6, the priority data file 136 stores the priority for operating the server for each server type. FIG. 8 is a diagram illustrating an example of information stored by the priority data file 136 according to the first embodiment. For example, the priority data file 136 stores the priority for each server type for each communication network device, as shown in FIG. For example, the priority data file 136 stores “front server 1 = front server 2> front server 3” in association with “communication network: A”. Here, the above-described information means that the priority of operating the front server 3 is lower than that of the front server 1 and the front server 2.

  Returning to FIG. 6, the start / stop condition management file 137 stores various conditions for starting or stopping each server. Specifically, when starting or stopping each server, the start / stop condition management file 137 stops an identifier of another server that needs to be started or stopped in advance or a server with a low priority. 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. 9A is a diagram illustrating a first example of information stored by the start / stop condition management file 137 according to the first embodiment. For example, as illustrated in FIG. 9A, the start / stop condition management file 137 according to the first embodiment includes a CPU usage rate threshold value for determining whether the processing load is low for each server, and a high value. The CPU usage rate threshold value for determining whether or not it is a load is stored.

  FIG. 9B is a diagram illustrating a second example of information stored by the start / stop condition management file 137 according to the first embodiment. For example, the start / stop condition management file 137 according to the first embodiment stores a constraint for stopping the server for each server, as illustrated in FIG. 9B. For example, the start / stop condition management file 137 according to the first embodiment stores “front server 1 and front server 2 operate normally” in association with “front server 3”. Here, the above information means that the front server 1 and the front server 2 need to be operating normally in order to stop the front server 3. The information illustrated in FIGS. 9A and 9B is merely an example, and for example, the memory usage may be used as a threshold value for determining the load status of the server.

  Returning to FIG. 6, the log file 138 stores the processing content executed by the server configuration control apparatus 100. Specifically, the log file 138 stores the processing contents of the server configuration control apparatus 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 135, the priority data file 136, and the start / stop condition management file 137 are: It is 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 identifying unit 141 identifies the front server 1, the front server 2, the front server 3, 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 acquires the operation status from the server corresponding to the communication address acquired by the communication address data acquisition unit 142 and stores it in the operation status management file 134. 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, and stores them in the operating status management file 134.

  The server start / stop determination unit 144 determines a server to be started or stopped based on the processing load acquired by the server operation status acquisition unit 143. Specifically, the server start / stop determination unit 144 first refers to the threshold stored in the stop condition management file 137 to determine the current load state of the server acquired by the server operation status acquisition unit 143. . For example, the server start / stop determination unit 144 refers to the threshold stored in the stop condition management file 137, and the front servers 1 to 3, the DB servers 1 and 2, and the log server acquired by the server operation status acquisition unit 143. It is determined whether the processing load amount of 1 is in a high load state and whether it is in a low load state.

  Then, the server start / stop determination unit 144 determines the number of servers to be started or stopped. Specifically, the server start / stop determination unit 144 determines the number of servers to be started or stopped based on the correspondence between the number of servers to be started or stopped and the threshold stored in the start / stop condition management file 137. decide. Here, as a correspondence relationship between the number of servers to be started or stopped and the threshold, for example, information in which the number of servers is associated with an arbitrary threshold, or an excess when the current processing load of the server exceeds the threshold For example, information in which the number of servers is associated with each other.

  Then, the server start / stop determination unit 144 determines the determined number of servers as targets to be started or stopped. Specifically, the server start / stop determination unit 144 determines a server to be started or stopped based on the server priority stored by the priority data file 136. For example, the server activation / determination determining unit 144 determines a server to be activated or deactivated in order of high priority or low priority.

  Then, the server start / stop determination unit 144 obtains the constraint condition applied to the server start / stop determined as the target of start / stop from the start / stop condition management file 137, and the others specified in the constraint condition Specify the server and the contents of the condition. For example, the server activation / determination determining unit 144 refers to the information illustrated in FIG. 9B and specifies a constraint condition for starting or stopping the server determined as the activation or deactivation target.

  The server activation / deactivation request unit 145 controls the activation or deactivation of the server determined as the activation or deactivation target after controlling other servers to satisfy the constraint conditions determined by the server activation / deactivation determination unit 144 To do. A start request command or a stop request command is transmitted to a server on the communication network. The log management unit 146 stores the processing content by the server configuration control apparatus 100 in the log file 138.

  Next, a processing procedure of the server configuration control apparatus 100 according to the first embodiment will be described with reference to FIGS. 10A to 10C. 10A to 10C are sequence diagrams illustrating a processing procedure performed by the server configuration control apparatus according to the first embodiment. 10A to 10C show the processing procedure by the server configuration control apparatus 100 in the order of FIGS. 10A, 10B, and 10C. 10A to 10C exemplify a case where the CPU usage rate of each front server is lower than the threshold value for stopping the front server with the lowest priority for operation. Further, in FIGS. 10A to 10C, when the front server 3 is stopped, an abnormal state occurs while the process of the front server 3 is stopped, and the stop of the front server 3 fails. In the following, processing by the server configuration control apparatus 100 will be described using each unit of the server configuration control apparatus 100.

  As illustrated in FIG. 10A, in the server configuration control apparatus 100 according to the first embodiment, the server operation status acquisition unit 143 includes the front server 1, the front server 2, the front server 3, the DB server 1, the DB server 2, and the log server. 1. An acquisition request for the processing load of each server is transmitted to each of the log servers 2 (step S201). When the front server 1, the front server 2, the front server 3, the DB server 1, the DB server 2, the log server 1, and the log server 2 receive a processing load amount acquisition request from the server operation status acquisition unit 143, The CPU usage rate used to execute the processing requested by the CPU etc. is returned as the processing load amount (steps S202 to S208). The server configuration control apparatus 100 refers to the communication network apparatus data file 131, the server configuration file 132, and the communication address data file 133 before the processing load amount acquisition request by the server operation status acquisition unit 143 is transmitted. The communication address of each server is acquired.

  When the processing load amount is received from each server, the server start / stop determination unit 144 records the CPU usage rate received from each server in the start / stop condition management file 137, and the CPU for stopping the server Compare with thresholds such as usage rate. Then, when detecting that the CPU usage rate of the front server 1, the front server 2, and the front server 3 is lower than the threshold, the server start / stop determination unit 144 determines that the processing load amount of the front server satisfies the stop condition. (Step S209), the comparison result is recorded in the log file 138.

  Then, the server start / stop determination unit 144 refers to the correspondence between the number of servers to be stopped and the threshold stored in the start / stop condition management file, determines the number of servers to be stopped as one, and priorities Based on the priority of the front server stored in the data file, it is determined that the front server 3 is to be stopped. Further, the server start / stop determination unit 144 refers to the stop order stored in the communication network device start / stop file 135 and determines to stop the log server 2 when the front server 3 is stopped. (Step S210).

  Thereafter, the server start / stop determination unit 144 refers to constraints such as the stop order of the front server 3 and the log server 2 (step S211). Here, the server activation / deactivation determination unit 144 first confirms that the front server 1 and the front server 2 must be activated and operating normally when stopping the front server 3. To do.

  When the server start / stop determination unit 144 specifies from the communication network device start / stop file 135 that the server to be stopped first is the front server 3, the connection state to the front server 1 and the operation of the OS of the front server 1 In order to check the status and the like, after acquiring the communication address of the front server 1 from the communication address data file, the network connection status is checked with respect to the front server 1 (step S212). When a network connection status response is received from the front server 1 (step S213), the server start / stop determination unit 144 checks the process / OS operating status (step S214). When the server start / stop determination unit 144 receives a process / OS operation status response from the front server 1 (step S215), the server start / stop determination unit 144 determines that the front server 1 is operating normally.

  Next, the server start / stop determination unit 144 obtains the communication address of the front server 2 from the communication address data file, and then checks the network connection status with the front server 2 (step S216). When the connection status response is received (step S217), the process / OS operating status is confirmed (step S218). When the server start / stop determination unit 144 receives a process / OS operation status response from the front server 2 (step S219), the server start / stop determination unit 144 determines that the front server 2 is operating normally.

  Then, the server start / stop determination unit 144 obtains the communication address of the front server 3 from the communication address data file, and then checks the network connection status with the front server 3 (step S220). When the status response is received (step S221), the process / OS operating status is confirmed (step S222). Upon receiving a process / OS operating status response from the front server 3 (step S223), the server start / stop determination unit 144 determines that the front server 3 can be stopped (step S224).

  Then, the server start / stop request unit 145 transmits a process / OS / power stop request to the front server 3 (step S225). Here, when a front server failure occurs and a process / OS / power stop (error response) is returned (step S226), the server start / stop determination unit 144 detects that the process stop has failed, The log file 138 records that the front server 3 was not stopped normally and the operating state of the process of the front server 3. Then, the server start / stop determination unit 144 confirms the server to be stopped next (step S227), and specifies that the server is the log server 2.

  Thereafter, the server activation / determination determining unit 144 refers to the restrictions stored in the activation / deactivation condition management file, and confirms whether or not the log server 2 can be deactivated when the front server 3 cannot be deactivated (step S228). It is determined that the log server 2 can be stopped (step S229).

  When it is determined that the server to be stopped next is the log server 2 and it is determined that the server can be stopped, the server start / stop determination unit 144 checks the connection state of the log server 2 and the operating state of the OS of the log server 2. In addition, after obtaining the communication address of the log server 2 from the communication address data file, the network connection status is confirmed with respect to the log server 2 (step S230). When a network connection status response is received from the log server 2 (step S231), the server start / stop determination unit 144 checks the process / OS operating status (step S232). Upon receiving a process / OS operating status response from the log server 2 (step S233), the server start / stop determination unit 144 determines that the log server 2 can be stopped (step S234).

  Then, the server start / stop request unit 145 transmits a process / OS / power stop request to the log server 2 (step S235). Upon receiving the process / OS / power stop request, the log server 2 responds to the process / OS / power stop (step S236) and then stops the server (step S237). Then, when the server start / stop request unit 145 receives the process / OS / power stop, the server start / stop request unit 145 records in the log file 138 that the log server 2 has been normally stopped, and then stops the log server 2 next. Make sure there is no server. Then, the server configuration control apparatus 100 stands by until the time for confirming the processing load amount of the next server (step S238).

  The above-described processing procedure is merely an example, and the server configuration control apparatus 100 according to the first embodiment can execute the same processing in other server stop processing and server startup processing. .

[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 configuration control apparatus that controls the server, the start / stop condition management file 137 is a restriction condition applied to starting or stopping each server, and for each server, a predetermined condition is satisfied when starting or stopping the server. Another server to be stored and a constraint condition indicating the contents of the condition are stored. Then, the server operation status acquisition unit 143 acquires at least one of the processing load amount in each server and the power amount used for the operation of each server. Then, the server start / stop determination unit 144 determines a target server to be started or stopped based on at least one of the processing load amount and the power amount acquired by the server operation status acquisition unit 143. In addition, the server start / stop determination unit 144 acquires the restriction conditions applied to the start or stop of the determined target server from the start / stop condition management file 137, and sets other servers and conditions specified in the restriction conditions. Identify content. Then, the server start / stop request unit 145 performs control so that the other server specified by the server start / stop determination unit 144 satisfies the condition specified by the server start / stop determination unit 144, and then the server start / stop The target server determined by the determination unit 144 is started or stopped. Therefore, the server configuration 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 stop procedure is required. However, it is possible to quickly optimize the processing load of each server without determining whether or not to stop each server.

  Further, according to the first embodiment, the server start / stop determination unit 144 pre-configures for each server when the processing load amount or the power amount acquired by the server operation status acquisition unit 143 exceeds an arbitrary threshold. The target server is determined in the order of priority for operating the set server. Therefore, the server configuration control apparatus 100 according to the first embodiment can perform flexible configuration control in consideration of the performance of each server.

  Further, according to the first embodiment, the start / stop condition management file 137 stores, as the contents of the constraint conditions, the order of start and stop, the dependency between servers, and the processing when control fails. Therefore, the server configuration control apparatus 100 according to the first embodiment allows the maintenance person of the communication network to determine whether or not each server can be stopped even if a complicated stop procedure is necessary depending on the operating state of each server configuring the communication network. It is possible to quickly optimize the processing load on each server without determining the procedure.

  In the first embodiment described above, a case has been described in which the processing load amount of the server is periodically acquired and the start or stop of the server is controlled based on the current processing load amount. In the second embodiment, a case will be described in which the server start or stop is controlled during a preset time period.

  FIG. 11 is a schematic diagram illustrating an example of a communication network according to the second embodiment. For example, as shown in FIG. 11, the communication network apparatus A and the server configuration control apparatus 100a are connected to the communication network according to the second embodiment. 11 is the same as the communication network apparatus A shown in FIG. As illustrated in FIG. 11, the server configuration control apparatus 100 a according to the second embodiment controls the front server 3 and the log server 2 to stop during “22:00:00 to 7:00”. Details of the server configuration control apparatus 100a according to the second embodiment will be described below.

  First, the configuration of the server configuration control apparatus 100a according to the second embodiment will be described. FIG. 12 is a diagram illustrating an example of the configuration of the server configuration control apparatus 100a according to the second embodiment. The server configuration control apparatus 100a according to the second embodiment has a new server stop time management file 139 as compared to the server configuration control apparatus 100 according to the first embodiment and the server start / stop determination unit 144. Processing contents are different. Hereinafter, these will be mainly described.

  The server stop time management file 139 stores the time to stop each server and the time to start each server. FIG. 13 is a diagram illustrating an example of information stored by the server stop time management file 139 according to the second embodiment. For example, the server stop time management file 139 stores information in which stop times are associated with servers as shown in FIG. For example, the server stop time management file 139 stores “22:00 to 7:00” in association with “front server 3”. The above-described information means that the front server 3 is stopped between 22:00 and 7:00. Information stored by the server stop time management file 139 is registered in advance by a maintenance person of the server configuration control apparatus 100a. For example, a time zone that is expected to have a small processing load is registered as a stop time, or a time zone that is expected to have a large processing load is registered as a start time.

  The server start / stop determination unit 144 determines a server to be started or stopped from a server group connected to the communication network based on the server stop time or start time stored by the server stop time management file 139.

  Next, a processing procedure of the server configuration control apparatus 100a according to the second embodiment will be described with reference to FIGS. 14A to 14C. 14A to 14C are sequence diagrams illustrating a processing procedure performed by the server configuration control apparatus 100a according to the second embodiment. 14A to 14C show the procedure of processing by the server configuration control apparatus 100a in the order of FIGS. 14A, 14B, and 14C. 14A to 14C, the server configuration control is performed so that the front server 3 and the log server 2 are stopped during the period from 22:00 to 7:00 every day, which is expected to have a small amount of processing request from the front server. The case where it is registered in advance in the apparatus 100a is taken as an example. Hereinafter, processing by the server configuration control apparatus 100a will be described using each unit included in the server configuration control apparatus 100a.

  As shown in FIG. 14A, in the server configuration control apparatus 100a according to the second embodiment, the maintenance server adds the front server 3 and the log server 2 to the server stop time management file 139 held by the server configuration control apparatus 100a every day. It is recorded in advance to stop at 0:00. The maintenance person then executes a read request command for the server stop time management file 139 to the server configuration control apparatus 100a in order to reflect the recorded contents of the server stop time management file 139 in the operation of the server configuration control apparatus 100a.

  When the time reaches 22:00 (Yes at Step S301), the server start / stop determination unit 144 starts the stop processing of the front server 3 and the log server 2 (Step S302) and stops the log file 138. Record that started.

  Subsequently, the server start / stop determination unit 144 determines that the front server 3 and the log server 2 are to be stopped (step S303), and checks restrictions such as the stop order of the front server 3 and the log server 2 (step S303). S304). Here, when the front server 3 is stopped, the server start / stop determination unit 144 confirms that the front server 1 and the front server 2 need to be started and operating normally.

  When the server start / stop determination unit 144 specifies from the communication network device start / stop file 135 that the server to be stopped first is the front server 3, the connection state to the front server 1 and the operation of the OS of the front server 1 In order to check the status and the like, after acquiring the communication address of the front server 1 from the communication address data file, the network connection status is checked with respect to the front server 1 (step S305). When a network connection status response is received from the front server 1 (step S306), the server start / stop determination unit 144 checks the process / OS operating status (step S307). When the server start / stop determination unit 144 receives a process / OS operation status response from the front server 1 (step S308), the server start / stop determination unit 144 determines that the front server 1 is operating normally.

  Next, after obtaining the communication address of the front server 2 from the communication address data file, the server start / stop determination unit 144 checks the network connection status with the front server 2 (step S309), and the front server 2 sends the network to the network. When the connection status response is received (step S310), the process / OS operating status is confirmed (step S311). When the server start / stop determination unit 144 receives a process / OS operation status response from the front server 2 (step S312), the server start / stop determination unit 144 determines that the front server 2 is operating normally.

  Then, the server start / stop determination unit 144 acquires the communication address of the front server 3 from the communication address data file, and then checks the network connection status with the front server 3 (step S313). When the status response is received (step S314), the process / OS operating status is confirmed (step S315). When receiving the process / OS operating status response from the front server 3 (step S316), the server start / stop determination unit 144 determines that the front server 3 can be stopped (step S317).

  Then, the server start / stop request unit 145 transmits a process / OS / power stop request to the front server 3 (step S318). Upon reception of the process / OS / power stop request, the front server 3 responds to the process / OS / power stop (step S319) and then stops the server (step S320). Then, when the server start / stop request unit 145 receives the process / OS / power stop, the server start / stop request unit 145 records in the log file 138 that the front server 3 has been normally stopped.

  Then, the server start / stop determination unit 144 confirms the server to be stopped next (step S321) and specifies that the server is the log server 2. When it is determined that the server to be stopped next is the log server 2, the server start / stop determination unit 144 checks the connection state of the log server 2 and the operating state of the OS of the log server 2 to check the log server 2. After obtaining the communication address from the communication address data file, the network connection status is confirmed with respect to the log server 2 (step S322). When a network connection status response is received from the log server 2 (step S323), the server start / stop determination unit 144 checks the process / OS operating status (step S324). When receiving the process / OS operating status response from the log server 2 (step S325), the server start / stop determination unit 144 determines that the log server 2 can be stopped (step S326).

  Then, the server start / stop request unit 145 transmits a process / OS / power stop request to the log server 2 (step S327). Upon receiving the process / OS / power stop request, the log server 2 responds to the process / OS / power stop (step S328) and then stops the server (step S329). Then, when the server start / stop request unit 145 receives the process / OS / power stop, the server start / stop request unit 145 records in the log file 138 that the log server 2 has been normally stopped, and then stops the log server 2 next. Make sure there is no server. Then, the server configuration control apparatus 100a waits until the next server stop processing time (step S330).

  Note that the above-described processing procedure is merely an example, and the server configuration control apparatus 100a according to the second embodiment can execute similar processing in other server stop processing and server start processing. . Further, in combination with the first embodiment, the present invention can also be applied to a case where each server constituting the communication network device is stopped when the required processing load is small and stopped at a pre-registered time.

[Effect of Example 2]
As described above, according to the second embodiment, when the server configuration control apparatus 100a systematically stops the front server 3 and the log server 2 at the time when the processing request amount of the front server is assumed to be small, Are stopped in the order in accordance with the dependency of the operation, or the log server 2 is determined whether or not to stop after confirming the stop execution result of the front server 3, so that between the types of servers constituting the communication network Even if there is an operation dependency or a complicated stop procedure is required, the server configuration control apparatus 100a does not determine whether or not each server can be stopped and does not determine the stop procedure. It is possible to optimize the load amount quickly and in an optimum time zone.

  In the first embodiment and the second embodiment described above, the case where the start and stop of the server are controlled based on the processing load amount has been described. In the third embodiment, a case will be described in which starting and stopping of a server are controlled based on the amount of power used to operate a server group. In the third embodiment, first, a problem will be described with an example of a conventional technique for controlling start or stop of a server based on an electric energy, and then a server configuration control device of the present application will be described.

  FIG. 15 is a schematic diagram illustrating an example of a communication network according to the related art. For example, as shown in FIG. 15, a communication network device and a server configuration control device are connected to the communication network. In FIG. 15, two communication network devices are shown, but in reality, 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 illustrated in FIG. 15, the communication network device includes a front server, a DB server, and a log server. The front server is connected to the power management apparatus A, the DB server is connected to the power management apparatus B, and the log server is connected to the power management apparatus C to be supplied with power from an external power source.

  Generally, when managing the power supply state to each device and air conditioning equipment installed in a server room, as shown in FIG. 15, a power management device is installed in the server room and connected to an external power source. In a communication network system in which the power management device is connected between each server that constitutes the communication network device and the external power supply, the power management device possesses the power management device when the power supply from the external power supply stops. Power is temporarily supplied to each server using a battery that is installed.

  When the server configuration control apparatus appropriately acquires the power supply state from the power management apparatus to each server and detects that the power supply from the external power supply has stopped, the server configuration control apparatus connects to the external power supply. A stop request command is executed for each server that is supplied with power from the power management apparatus.

  FIG. 16 is a diagram illustrating an example of a configuration of a server configuration control apparatus 200a according to the related art. In FIG. 16, the same reference numerals are given to the same parts as those of the server configuration control apparatus 200 according to the related art shown in FIG. 3. That is, the server configuration control apparatus 200a is different from the server configuration control apparatus 200 in that the server configuration control apparatus 200a newly includes a power consumption amount management unit 247. The power consumption management unit 247 acquires information on the amount of power supplied from the communication network power management apparatus to the server room. Then, the server activation / deactivation request unit 245 controls activation or deactivation of the server based on the amount of power acquired by the power consumption amount management unit 247.

  FIG. 17 is a sequence diagram illustrating an example of processing performed by the server configuration control apparatus 200a according to the related art. In the server configuration control apparatus 200a according to the prior art, first, a stop request command for stopping the communication network apparatus is registered in advance in the server configuration control apparatus 200a for each server configuring the communication network apparatus. Further, when the power supply from the external power source connected to each power management apparatus is stopped, registration for notifying the server configuration control apparatus 200a that the power supply is stopped is performed in the power management apparatus (step). S401).

  Next, the server configuration control apparatus acquires a power supply state to each server connected to the power management apparatus from each power management apparatus periodically or appropriately. Here, when a power supply stop notification is received (step S402), the server configuration control device 200a starts executing a DB server stop process (step S403), and transmits a stop request to the DB server (step S404).

  Upon receiving the stop request, the DB server returns a stop request response (step S405) and stops the server (step S406). Then, the maintenance person of the communication network device confirms whether or not each server has been normally stopped. If the maintenance is not carried out normally, the maintenance person will investigate the cause, and the maintenance person will again stop the server.

  As described above, the server configuration control apparatus 200a according to the related art only controls the stop of the server to which power is supplied from the power management apparatus that has transmitted the notification in response to the stop of the power supply notification. Therefore, when there is a restriction on operation between different server types, the server cannot be started or stopped.

  Therefore, the server configuration control apparatus according to the third embodiment can quickly optimize the power consumption even when there is a restriction when starting or stopping between different server types. Objective.

  FIG. 18 is a schematic diagram illustrating an example of a communication network according to the third embodiment. For example, as shown in FIG. 18, the communication network apparatus A and the server configuration control apparatus 100b are connected to the communication network according to the third embodiment.

  As shown in FIG. 18, the communication network apparatus A is installed in a server room α and includes a subset A1 and a subset A2. The servers constituting the subset A1 and the subset A2 are the same as those in the first and second embodiments. Each server constituting the communication network device A is connected to the power management devices A to G between the external power sources. The server room α includes electrical equipment such as air conditioning equipment, and the electrical power management device H is connected between the electrical equipment and an external power source. Each power management device monitors the power consumption of the connected server or electrical equipment, and responds to the power consumption of the server or electrical equipment when an inquiry about the power consumption is received from the external input interface.

  A configuration of the server configuration control apparatus 100b according to the third embodiment will be described. FIG. 19 is a diagram illustrating an example of the configuration of the server configuration control apparatus 100b according to the third embodiment. Note that the server configuration control apparatus 100b according to the third embodiment has a new power consumption management unit 147, an operating state management file 134, and start / stop compared to the server configuration control apparatus 100 according to the first embodiment. The information stored by the condition management file 137 and the processing contents by the server start / stop determination unit 144 are different. Hereinafter, these will be mainly described.

  The power consumption amount management unit 147 periodically acquires the power consumption amount of each server constituting the communication network device A and the power consumption amount of the server room α from the power management devices A to H. Then, the power consumption management unit 147 stores the acquired power consumption in the operating state management file.

  The operating state management file 134 stores the power consumption of each server constituting the communication network apparatus A and the power consumption of the server room α. Specifically, the operating state management file 134 stores the power consumption of each server and the power consumption of the server room α acquired by the power consumption management unit 147.

  The start / stop condition management file 137 stores, in addition to various restrictions, the threshold value of the power consumption amount of the server room α when the server is started or stopped, and the correspondence relationship between the number of servers and the threshold value.

  The server start / stop determination unit 144 determines a server to be started or stopped based on the power consumption amount of the server room α stored by the operation state management file 134. Specifically, the server start / stop determination unit 144 compares the total amount of power consumption acquired from each power management apparatus with the threshold value of power consumption stored by the start / stop condition management file 137. Thus, the server to be started or stopped is determined.

  Next, a processing procedure of the server configuration control apparatus 100b according to the third embodiment will be described with reference to FIGS. 20A to 20D. 20A to 20D are sequence diagrams illustrating a processing procedure performed by the server configuration control apparatus 100b according to the third embodiment. 20A to 20D show the processing procedure by the server configuration control apparatus 100b in the order of FIGS. 20A, 20B, 20C, and 20D. 20A to 20D exemplify a case where the power consumption of the server room α is higher than the threshold value for stopping the front server with the lowest priority for operation. 20A to 20D, as an example, when the front server 3 is stopped, an abnormal state occurs while the front server 3 is stopped and the front server 3 fails to stop. In the following, processing by the server configuration control apparatus 100b will be described using each unit included in the server configuration control apparatus 100b.

  As illustrated in FIG. 20A, in the server configuration control apparatus 100b according to the third embodiment, the power consumption management unit 147 requests the power management apparatuses A to H to acquire the power consumption of each power management apparatus. Is transmitted (step S501). Upon receiving the power consumption acquisition request from the power consumption management unit 147, each of the power management apparatuses A to H responds with the amount of power supplied to the server as the power consumption (steps S502 to S509). . In the server configuration control apparatus 100b, the communication network apparatus data file 131, the server configuration file 132, and the communication address data file 133 are referred to before the power consumption amount acquisition request from the power consumption management unit 147 is transmitted. The communication address of each server is acquired.

  When the power consumption amount is received from each power management apparatus, the server start / stop determination unit 144 stores the server whose total power consumption amount acquired from each power management apparatus is recorded in the start / stop condition management file 137. Compare with the threshold value of power consumption when stopping. Then, when detecting that the total amount of power consumption is higher than the threshold, the server start / stop determination unit 144 determines that the processing load amount of the front server satisfies the stop condition (step S510), and the comparison result is a log file. 138.

  Then, as shown in FIG. 20B, the server start / stop determination unit 144 refers to the correspondence between the number of servers to be stopped and the threshold stored in the start / stop condition management file, and sets the number of servers to be stopped to one. And determining to stop the front server 3 based on the priority of the front server stored in the priority data file. Further, the server start / stop determination unit 144 refers to the stop order stored in the communication network device start / stop file 135 and determines to stop the log server 2 when the front server 3 is stopped. (Step S511).

  Thereafter, the server start / stop determination unit 144 confirms restrictions such as the stop order of the front server 3 and the log server 2 (step S512). Here, the server activation / deactivation determination unit 144 first confirms that the front server 1 and the front server 2 must be activated and operating normally when stopping the front server 3. To do.

  When the server start / stop determination unit 144 specifies from the communication network device start / stop file 135 that the server to be stopped first is the front server 3, the connection state to the front server 1 and the operation of the OS of the front server 1 In order to confirm the status and the like, after acquiring the communication address of the front server 1 from the communication address data file, the network connection status is confirmed with respect to the front server 1 (step S513). When a network connection status response is received from the front server 1 (step S514), the server start / stop determination unit 144 checks the process / OS operating status (step S515). When the server start / stop determination unit 144 receives a process / OS operation status response from the front server 1 (step S516), the server start / stop determination unit 144 determines that the front server 1 is operating normally.

  Next, the server start / stop determination unit 144 acquires the communication address of the front server 2 from the communication address data file, and then checks the network connection status with the front server 2 (step S517). When the connection status response is received (step S518), the process / OS operating status is confirmed (step S519). When the server start / stop determination unit 144 receives a process / OS operation status response from the front server 2 (step S520), the server start / stop determination unit 144 determines that the front server 2 is operating normally.

  Then, the server start / stop determination unit 144 acquires the communication address of the front server 3 from the communication address data file, and then checks the network connection status with the front server 3 (step S521). When the status response is received (step S522), the process / OS operating status is confirmed (step S523). Upon receiving a process / OS operating status response from the front server 3 (step S524), the server start / stop determination unit 144 determines that the front server 3 can be stopped (step S525).

  Then, the server start / stop request unit 145 transmits a process / OS / power supply stop request to the front server 3 (step S526). Here, when a failure occurs in the front server 3 and a process / OS / power stop (error response) is returned (step S527), the server start / stop determination unit 144 detects that the process stop has failed. At the same time, the log file 138 records that the front server 3 was not stopped normally and the operating state of the process of the front server 3. Then, the server start / stop determination unit 144 confirms the server to be stopped next (step S528), and specifies that the server is the log server 2.

  Thereafter, the server activation / determination determining unit 144 refers to the constraints stored in the activation / deactivation condition management file and confirms whether or not the log server 2 can be deactivated when the front server 3 cannot be deactivated (step S529). It is determined that the log server 2 can be stopped (step S530).

  When it is determined that the server to be stopped next is the log server 2 and it is determined that the server can be stopped, the server start / stop determination unit 144 checks the connection state of the log server 2 and the operating state of the OS of the log server 2. In addition, after obtaining the communication address of the log server 2 from the communication address data file, the network connection status is confirmed with respect to the log server 2 (step S531). When a network connection status response is received from the log server 2 (step S532), the server start / stop determination unit 144 checks the process / OS operating status (step S533). When the server start / stop determination unit 144 receives a process / OS operation status response from the log server 2 (step S534), the server start / stop determination unit 144 determines that the log server 2 can be stopped (step S535).

  Then, the server start / stop request unit 145 transmits a process / OS / power stop request to the log server 2 (step S536). Upon receiving the process / OS / power stop request, the log server 2 responds to the process / OS / power stop (step S537) and then stops the server (step S538). Then, when the server start / stop request unit 145 receives the process / OS / power stop, the server start / stop request unit 145 records in the log file 138 that the log server 2 has been normally stopped, and then stops the log server 2 next. Make sure there is no server. Then, the server configuration control apparatus 100b waits until the next power consumption confirmation time (step S539).

  Note that the above-described processing procedure is merely an example, and the server configuration control apparatus 100b according to the third embodiment can execute similar processing in other server stop processing and server start processing. .

[Effect of Example 3]
As described above, according to the third embodiment, the server configuration control device 100b consumes a large amount of power in the server room α, and when the front server 3 is stopped, the log server 2 is also stopped from the communication network device start / stop file. Confirm that you want to stop, and stop each server in the order according to the operational dependency. Therefore, the server configuration control apparatus 100b according to the third embodiment can maintain the communication network even if there is an operation dependency between the types of servers constituting the communication network or a complicated stop procedure is required. However, it is possible to quickly optimize the power consumption of the server room α without determining whether or not to stop each server.

  Further, according to the third embodiment, the server configuration control apparatus 100b stops the log server 2 to be stopped next to the front server 3 using the start / stop condition management file when the front server 3 fails to stop. After confirming availability, the log server 2 is stopped after determining that it can be stopped. Therefore, the server configuration control apparatus 100b allows the maintenance person of the communication network to determine whether or not to stop each server even if a complicated stop procedure is required depending on the operating state of each server constituting the communication network. In addition, it is possible to quickly optimize the power consumption of the server room α.
