Description

  The present invention is a system management technique for managing program execution in a plurality of computers.

  A so-called job management system is known that executes a job according to a preset job net. Here, the “job” is a single command or a script describing a plurality of commands and program execution procedures. For example, when executing the backup command BU of the backup tool A, this command BU and its parameters are specified as the job definition. Such a system management technique is disclosed in Japanese Patent Application Laid-Open No. 2001-282551.

  In such a job management system, for example, the user sets a job net while looking at the setting screen shown in FIG. The setting screen of FIG. 9 shows an example that enables setting related to a job. For example, in the “execution host” setting item 91 of the property setting frame 84 of the job A1, “Host 20” is set as the identifier (usually the execution host name or IP address) of the computer executing the command, and the “command” setting item 92 is set in the “command” setting item 92. “Cmd1.exe” is specified as an execution command to be executed, and “-h Host40” is specified as a parameter to be passed to the command at the time of execution in the “parameter” setting item 93. Also, this example shows that job A2 is executed when job A1 is finished, and job A3 is executed when job A2 is finished.

JP 2001-282551 A

  Information systems using computer networks are widely used, but these systems are usually constructed and managed on a business unit basis as shown in FIG. One business system is composed of a plurality of computers connected to a network. Each computer is provided with a plurality of programs such as an operating system and middleware (for example, an application server program, a database management system, etc.) according to its use, and a business program.

  The operation of the business system is realized by executing the plurality of programs, and the execution control of the programs can be realized by executing the combination of operation commands. Many combinations of commands related to this operation can be standardized, and system operation can be automated by a job management system (also referred to as an operation management system).

  The job management system stores, as a job definition, a job flow definition that indicates which command is executed by which computer (also referred to as a computer or an information processing apparatus) by which parameter. That is, the job execution order is defined.

  However, in the conventional job management system, the purpose is to support the operation of the business system. However, as shown in the setting screen of FIG.

  This also depends on the diversity and versatility of the commands themselves handled by the job management system. That is, most of the software that provides commands is a so-called program product that provides general-purpose functions, and the command signature (command setting form) cannot be set to be related to a job. A plurality of software constituting the system is usually provided by a plurality of vendors, and the command levels and interfaces are different.

  For this reason, in the job management system, for example, even if the setting screen of FIG. 9 has sufficient functions for GUI operation, it means in a business system such as a computer that executes a command or a computer for a command parameter including a computer identifier. The user needs to be aware of the attachment, forcing the business developer who defines the job net to perform complicated work.

  For example, when designing the business system “E-shopping”, the system architecture is defined by a logical server such as “application server” or “database server”. Originally, in the definition of job nets, we would like to use the definitions in these upstream processes as well, such as “Application Server of E-Shopping System”. However, at present, the user independently determines which computer the application server indicates. It must be managed and reflected in the job net definition.

  This is not just a matter of name management. Also in the operation procedure, we are aware of the business system's semantics, such as “I want to set this operation monitoring condition for the operating system and middleware for the application server (in the system)”. This is because there are many cases where a job net should be defined. In this case, the user must consider the configuration of the entire business system as well as the correspondence of individual computers.

  These problems are exacerbated by the emergence of utility computing that consolidates hardware resources by blade server systems and SAN (Storage Area Network), and allocates hardware resources to business systems according to usage load conditions. There is a tendency.

  For example, a computer that was used in a certain daytime work is used in another nighttime work. As a result, the number of application servers for which monitoring conditions are to be set may change depending on the time zone. Under such circumstances, it is difficult to manually manage the correspondence between the system and the computer, and to manually change the definition of each job in the job net based on this correspondence information.

  An object of the present invention is to simplify the operation of a computer.

  Another object of the present invention is to efficiently manage the business system targeted by the job net by efficiently managing the job net, and to reduce the workload of the user involved in the business system operation. With the goal.

  In order to achieve the object of the present invention, in the present invention, a job management system for executing a plurality of jobs in which an operation procedure of a business system composed of a plurality of computers is defined in a job net format is provided. Is input, the parameters of each job constituting the job net are set based on the input logical system configuration definition, and the created job net is executed.

  First, in the system configuration definition, a logical configuration of a business system is defined based on a data model for describing the system, and the association between the defined logical server and a physical server in the real world is centrally managed. As a result, when the hardware used in the business system is changed, it is possible to cope with the hardware configuration change without changing the job net definition itself only by changing the correspondence information of the logical server.

  Next, the parameters of each job constituting the job net are defined using the information of the system configuration definition. In particular, the information defined in the system definition can be given to the execution host or command parameter of the command set as the job definition as meta information including the values that can be taken. For example, a logical server such as “APS1 as an application server of an E-shopping system” is designated as a command execution host for a job. This makes it possible to define job nets that are conscious of business system semantics.

  This correspondence by adding meta information is an interface that does not depend on the format of the command provided from each software that is the source of the job.

  Finally, in the job net execution, the job net based on the system configuration definition is executed. Here, the execution host and parameters are determined from the meta information given at the time of job definition and the correspondence information between the logical server and the physical server in the system definition. In this process, when there are a plurality of corresponding execution hosts, the execution command of the job is repeatedly executed on each execution host. This makes it possible to define and execute a job net that is simple and independent of the physical configuration, even when “the same setting is collectively performed on application servers (in the system)”.

  As described above, the job net can be set and managed efficiently. In addition, it is possible to efficiently operate the business system targeted by the job net.

  According to the present invention, the operation of the system can be simplified.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the configuration of a job management system described as an embodiment of the present invention.
<Job management system>
This system is composed of computers 10, 20, 30, 40 connected via a network 1. Each computer 10, 20, 30, 40 has a CPU and a memory, and a program described below for realizing the present embodiment is stored in the memory. In the computers 10, 20, 30, and 40, an operating system is running, and the job management system executes jobs on the operating system according to the set job net. By doing in this way, execution control of the program in each computer becomes possible.

  The main functions of this system are a manager program (hereinafter referred to as “manager”) 11 that runs on the computer 10 and an agent program (hereinafter referred to as “agent”) 21 that runs on each of the computers 20, 30, and 40. 31, 41.

  Among them, the manager (program) 11 includes a system configuration definition process 12 in which the user defines the logical configuration of the system, a system configuration management process 13 in which the system configuration information 17 is managed, and a job net definition process 14 in which the user defines the job net. A job net management process 15 for managing the job net information 18, and a job net execution control process 16 for performing job net analysis, job schedule management, event handling, job and job net execution control and monitoring, and the like. . Each of these processing units is realized by a program. These programs can also be realized by hardware and objects.

The job net information 18 stored in the job net management process 15 includes definition information for each job constituting the job net, setting information about the execution order of each job, the start time of the job, and the like. The job definition information includes a command to be executed by the job, its parameters, host information for executing the command, and the like. The job net execution control process 16 monitors the date and time output by the built-in timer of the computer 10 and the execution status of the preceding job. When the job start timing defined in the job net information 18 arrives, the job net execution control process 16 For example, if the execution host is the computer 20, the agent 21 is instructed to execute the job. The agent 21 executes the command according to the request from the manager 11. Depending on the job net information 18, the execution host and parameters may include information on the system configuration information 17 defined by the user in the system configuration definition process 12. In this case, the job net execution control process 16 makes an inquiry to the system configuration management process 13 to determine the execution host and parameters.
<System configuration definition>
The agent of the job management system is usually deployed on the execution computer of the business system. FIG. 2 shows a configuration example of “E-shopping” as an example of the business system 60 using the computers 10, 20, 30, and 40. The business system 60 may include some application systems in addition to the “E-shopping” system.

  The business system 60 is a Web three-layer model system, which deploys a Web server (also referred to as an HTTP server) program 22 and an application server program 23 to the computer 20, and uses the same Web server program 32 and application server (AP server) program 33. The database 30 is arranged in the computer 30 and the database management system 41 is arranged in the computer 40. In addition, in order to automate a series of procedures related to the operation of the business system 60, agents (programs) 21, 31, and 41 of the job management system are deployed on the computers 20, 30, and 40, respectively. The manager 11 controls these agents.

  The system configuration definition process 12 provides a user interface that defines the logical configuration of the business system. FIG. 3 shows a configuration definition example of the business system 60 “E-shopping”. The system configuration definition process 12 models the elements “system” and “logical server” necessary for describing the system configuration as hierarchical data. As the logical server, for example, a “Web server”, “AP server”, “DB server”, etc. that constitute a typical Web three-tier system are provided as models.

  When the user defines the “E-Shopping” system 70 in the system configuration definition processing 12, the Web server 71 that is the type of logical server (also referred to as a computer type) of this system is WEB1 (74) and WEB2 (75). The AP server 72 is composed of APS1 (76) and APS2 (77), the DB server 73 is composed of DBS1 (78), WEB1 (74) and APS1 (76) are deployed in the computer 20, and WEB2 ( 75) and APS2 (77) are deployed on the computer 30 and DBS1 (78) is deployed on the computer 40. That is, two logical servers (logical computers) are allocated to each of the computers 20 and 30 which are physical servers (physical computers).

  This definition information is expressed in the form shown in the examples of FIGS. 3A to 3F, and the information input in the system configuration definition processing 12 is stored in the system configuration information 17 via the system configuration management processing 13. Stored. The system configuration information includes at least logical configuration information such as a system and elements constituting the system, and correspondence information between each logical configuration element and a physical element, and is stored in the system configuration information table 1100.

In this embodiment, only the system 70 corresponding to the manager 11, the Web server 71 that is a logical server, the AP server 72, and the DB server 73 are described as the data model of the system description, but this model is limited. It is not a thing. For example, model expansion such as “load balancer” and “mail server” as logical servers and a group “cluster group” that is transparently load-balanced by the load balancer as logical groups can be considered.
<Definition of job net>
FIG. 4 shows a definition screen 80 used when defining a job net in the job net definition process 14. The job net displayed on the definition screen 80 is defined to execute job A2 following job A1 and execute job A3 following job A2. In FIG. 4, “execution host”, “command”, “parameter” are displayed in the property setting frames 84 and 85 of the jobs A1 and A2 displayed in a balloon shape from the objects 81 and 82 corresponding to the jobs A1 and A2, respectively. , Etc., are provided. The property setting frames 84 and 85 may be displayed in a separate window. In the “execution host” setting item 91, an identifier of a computer on which the job is executed is set. In the setting item 92 of “command”, a command name activated by this job is set. In the “parameter” setting item 93, a parameter given when the command is started is set. A process is generated on the operating system by starting the command. A single job can include a plurality of processes.

  Here, the computer identifier set in the setting item 91 of “execution host” is conventionally a computer host name, an IP address, or a variable associated therewith. In this embodiment, the system configuration information 17 defined in the system configuration management process 13 can be used as meta information including these identifiers. For example, a logical server can be used instead of a physical server.

  As shown in FIG. 4, the value “? E-shopping / WEB1.host?” Of the “execution host” setting item 91 in the property setting frame 84 of job A1 is the system defined in FIG. It is a variable that receives host information of the logical server “WEB1” that is a member of “E-shopping”. The conventional identifier “Host 20” is assigned to this variable when the job net execution control process 16 inquires the system configuration management process 13 when executing the job A1.

  Further, the value “? E-shopping / @ AP server.host?” Of the “execution host” setting item 91 of the property setting frame 85 of the job A2 is the system defined in FIG. This is a variable for receiving host (group) information of an execution host whose type of logical server that is a member of “E-shopping” is “AP server”. “@” Indicates that the type can be received as a parameter. In this variable, the job net execution control process 16 makes an inquiry to the system configuration management process 13 at the time of execution of the job A2, and based on the system configuration definition shown in FIG. “Host 30” is assigned, and the command is executed on each of the computers 20 and 30.

  On the other hand, the meaning of each parameter received by the command is different. For example, a parameter that receives information included in the system configuration information 17 such as a parameter that receives a computer identifier can be handled in the same manner.

  For example, “? E-shopping / DBS1.host?” Of the “−h” option shown in the “parameter” setting item 93 of the property setting frame 84 of job A1 is the system “E-shopping” defined in FIG. This means that it is a variable that receives host information of the member logical server “DBS1”. When the job A1 is executed, the job net execution control process 16 makes an inquiry to the system configuration management process 13 so that the identifier “Host 40” of the computer 40 that is a conventional physical server is assigned to this variable.

  Note that a variable that refers to the system configuration information 17 such as “? E-shopping / WEB1.host?” Is referred to as a “system definition variable” in this embodiment.

The information input in the job net definition process 14 is stored in the job net information 18 via the job net management process 15, and the definition information of each job constituting the job net is stored in the job definition table 1000. For example, the “execution host” setting item 91 is held in the “execution host” column 1004, the “command” setting item 92 is held in the “execution command” column 10005, and the “parameter” setting item 93 is held in the “parameter information” column 1006. .
(Manager processing)
Next, processing of the job management system when executing a job net will be described. The process of the manager 11 [job execution control process 16] at the time of executing the job net is shown in the PAD diagram of FIG. When executing the set job net, the manager 11 performs an initial process (S101) such as initialization of a memory to be used, and then accepts a job net (S104), a job net analysis process (S105), and a job net Each process of the execution process (S106) is repeatedly executed until an end instruction interrupt is input (S102). Upon receiving the termination instruction, the manager 11 performs termination processing (S103).

  The PAD diagram shown in FIG. 6 shows details of the job net execution process (S106) of the manager 11 in FIG. The manager 11 selects one executable job (S112). The job that can be executed here refers to a job that is in a state in which execution start conditions such as termination of a preceding job and reception of an event are arranged among jobs managed by the job management system as waiting for execution. For the selected job, the manager 11 first acquires and analyzes the execution destination host information (1004) from the job definition table 1000 (S113), and determines whether the information includes the above-described system definition variable. (S114). Specifically, it is checked whether the “execution host” information 1004 of the job net definition includes a system definition variable surrounded by “?”.

If there is a system definition variable as a result of the check, the system configuration management process 13 is requested to resolve the variable (S115). The system configuration management process 13 compares the system configuration information 17 to be managed with the system definition variable, and returns the value of the corresponding system definition variable. For example, with respect to “? E-shopping / WEB1.host?”, The element ID 1101 of the logical element whose affiliation system 1104 is “E-shopping” and whose logical name 1102 is “WEB1” is obtained from the system configuration information table 1100. The physical element 1105 whose logical element (element ID) 1101 is “00101” is acquired as “Host20”, and this value is returned.
Also, the parameter “? E-shopping / DBS1.host?” Obtains the element ID 1101 of the logical element whose belonging system 1104 is “E-shopping” and whose logical name 1102 is “DBS1” as “00105”. The physical name 1105 whose logical element (element ID) 1101 is “00105” is acquired as “Host 40”, and this value is returned. Here, for example, when there are N physical names indicating DBS 1, the command is transmitted to the same physical server with a parameter that is repeated N times and converted to the physical name.

  In addition, regarding “? E-shopping / @ AP server.host?” As described above, “@” means a type as described above, so that the affiliation system 1104 indicates that “E-shopping” The set of logical element element IDs 1101 whose type 1103 is “AP server” is acquired as “00103, 00104”, “Host 20 and Host 30” corresponding to the respective logical elements (element IDs) are acquired, and this set is acquired. It will be returned as a value. That is, a command and a parameter are transmitted to each of Host 20 and Host 30.

The job execution control process 16 extracts values one by one from the set of real hosts acquired as the values of the system definition variables and assigns them sequentially to the execution destination host (S118). The job is stored in the execution host information table 1200 and the job is executed (S117). This is repeated until there is no variable value assigned to the execution destination host (S116).
Here, as shown in FIG. 12, for example, the execution host information table 1200 includes a job net ID 1201, a job ID 1202, a multiplicity identifier 1203, a job name 1204, a logical host name 1205, a physical host name 1206, and the like. The multiplicity identifier 1203 is an identification number automatically assigned to identify a job when two or more execution hosts are registered as a result of execution host variable resolution for the same job ID 1202.

  If the “execution host” information does not include the system definition variable and the host information can be determined only by the parameter value, the job is executed using the information (S117). In this case, only the physical host name 1206 is registered in the execution host information table 1200, and the logical host name 1205 is not stored.

  The above processing (S112-S119) is repeated until there is no job included in the job net (S111).

  The PAD diagram shown in FIG. 7 shows details of the job execution process (S117) of the job net execution process in FIG. After the execution destination host is specified, the manager 11 acquires and analyzes the parameter information 1006 of the job from the job definition table 1000 (S121), and determines whether the parameter information includes a system definition variable (S122). Specifically, it is checked whether or not there is a system variable surrounded by “?” In the “parameter information” 1006 of the job net definition. Since the parameter of the job is not limited to one, there may be a plurality of system definition variables in the parameter information. If there is a system definition variable in the parameter information, the system configuration management process 13 is requested to resolve all the variables to obtain the values of the variables (S126), and the variable values are assigned to the parameters (S127). ) After all the unresolved variables are resolved, the confirmed parameter information is generated (S125). The process in which the system configuration management process 13 compares the system configuration information 17 with the system definition variable and returns the value of the corresponding system definition variable is the same as the process (S115) at the execution host described above.

  If the parameter information does not include system definition variables, the parameter values can be handled as confirmed parameter information.

Based on the parameter information thus determined and the execution command (1005) information acquired from the job definition table 1000, the execution job information of the job is determined. The manager 11 transmits this execution job information to the agent 21, 31, or 41 of the execution destination host specified earlier (S123). In this embodiment, the program and data for job execution are described as being set up in the computer when the job is executed. After the job is executed by the agent, the manager 11 receives the execution result from the agent (S124).
(Agent processing)
The processing of the agents 21, 31, 41 will be described with reference to the PAD diagram of FIG. The agents 21, 31, and 41 operating on the execution computer perform initial processing (S131) such as initialization of memory to be used, and then receive job execution information from the manager 11 (S134) and execute the job. Then, the job execution result is transmitted to the manager 11 (S136). Here, the job execution is to execute a command included in the job execution information with parameters included in the job execution information. Steps S134, S135, and S136 are repeatedly executed until an interruption (request) for the termination instruction of each process is input (S132). Upon receiving the termination instruction, the agents 21, 31, and 41 perform termination processing (S133).
Next, as a second embodiment, a mechanism for realizing execution status monitoring using a logical host name (logical name) in a job net execution monitoring situation will be described.
In the prior art, the job net monitoring screen (FIG. 19) for monitoring the execution status of a job net is composed of objects 121, 122, 123, and 124 representing each job, and an object 125 for notifying abnormality in a specific job. When the user selects the object 123 representing the job A3 on the job net monitoring screen, the status information 130 of the job A3 is displayed. At this time, the status information 130 includes a corresponding job name (131), an execution host name (132) indicating a physical host name on which the job is executed, a status (133) of the corresponding job, and the like. Since only the physical host name (physical name) is displayed as the execution host name (132) on this monitoring screen, the job execution status can be monitored only using the physical host name (physical name).
On the other hand, in the embodiment of the present invention, the job net monitoring screen as shown in FIG. 20 is displayed, and when the user selects the object (142) representing the job A2 with the object (144) for notifying abnormality, it corresponds. Status information 150 and 160 representing the job status is displayed on the screen. In this case, by displaying both the logical host names (logical names) 152 and 162 and the physical host names (physical names) 153 and 163 as execution hosts, it is possible to monitor job execution with the logical host names (logical names). ing.
Originally, a business administrator who monitors the execution status of a job net can easily understand the status if the execution status can be monitored using a familiar logical host name (logical name). On the other hand, if there is a possibility that a failure of a job is caused by a hardware failure of the execution host, the business administrator needs to inform the system administrator who manages resources such as servers of the occurrence of the failure. In this case, the information useful for the system administrator is not the logical host name (logical name) but the physical host name (physical name), so the logical host name (logical name) and physical host name (physical name) are displayed on the job execution monitoring screen. ) Can be displayed effectively.
In FIG. 20, two pieces of status information 150 and 160 for displaying the status are displayed for one job A2 (142). This is because, as in the first embodiment, when defining an execution host name using a variable when defining a job net, depending on the system configuration, there is a job net that has multiple execution hosts for one job name. This is because it can be defined. Job A2 (142) in FIG. 20 is defined as “AP server of E-shopping system” as an execution host when defining a job net, so that APS1 and APS2 (in the physical host name (physical name), Host 20 and Host 30) The example which will be performed by two of these is shown.
In order to identify individual jobs from such overlapping job names, a multiplicity identifier described later is assigned to distinguish the jobs.
FIG. 13 is an overall configuration diagram for explaining the second embodiment.
<Job execution monitoring>
In FIG. 13, in addition to FIG. 1 described in the first embodiment, the manager 11 displays a monitoring screen display process 19 for displaying the execution status of a job specified by the user, and agents 21, 31, 41 during job execution. A log information management process 20 for storing the received event information in the event log information 23 and a status management process 21 for changing and managing the job status information 22 according to the contents of the event are provided.
The PAD diagram of FIG. 14 shows the flow of processing from when a user selects a specific job to when job status information is displayed during job net execution. When the user selects job A2 (142) whose execution status is to be confirmed on the job net monitoring screen, the objects 141, 142, and 143 on the job net monitoring screen correspond to the job definition table 1000 (FIG. 10) and are selected. The values of the job net ID 1001, job ID 1002, and job name 1003 of the job are passed to the monitoring screen display process 19 through the job net management process 15 (S201). Next, the monitoring screen display process 19 compares the acquired job net ID and job ID value with the columns 1201 and 1202 of the execution host information table 1200 (FIG. 12) of the job net information 18 and determines the number of corresponding data (many Severity) is confirmed (S202). At this time, if a plurality of data corresponds, the following processing (S204 to S206) is repeatedly executed for each multiplicity identifier 1203.
The monitoring screen display process 19 acquires the logical name 1205 and the physical name 1306 that are the execution host of the job from the execution host information table 1200 (FIG. 12) (S204). Subsequently, data in which the job net ID 1301, the job ID 1302, and the multiplicity identifier 1303 all match is searched from the job status table 1300 (FIG. 16) of the job status information 22, and the current status 1304 is acquired (S205). The management screen display processing 19 uses the acquired data as the job name 151 (or 161) and the logical host name 152 (or logical host name 152) as items of the status information 150 (or 160) corresponding to the job on the job net monitoring screen 140 (FIG. 20). Or 162), the values of the physical host name 153 (or 163) and the status 154 (or 164) are displayed on a monitoring monitor (not shown) (S206).
<Status update>
The flow of processing for maintaining the current status 1304 of the job status table 1300 (FIG. 16) in the latest state will be described with reference to the PAD diagram of FIG.
The event message transmitted from the agents 21, 31, 41 is received by the job net execution control process 16 of the manager 11 (S301). The job net execution control process 16 hands over the job net ID, job ID, multiplicity identifier, and physical host name of the job in which the event has occurred to the status management process 21 together with the received event message and occurrence time (S302). The status management process 21 stores the received information in the log table 1500 (FIG. 17) of the event log information 23 (S303). Next, the status management process 21 compares the received event message with the status change table 1400 (FIG. 18) of the job status information 22, and acquires the status 1403 after receiving the event (S304).
