  2. Description of the Related Art Conventionally, a mechanism in which a computer manages itself in order to reduce the burden of managing a computer system by humans, so-called autonomous computing is known. In autonomous computing, when a failure occurs in a computer system, it is possible to repair the autonomous failure of the autonomous system based on a predetermined operation guideline (hereinafter referred to as a policy).

  In addition, since the system state is complicated by various factors, it is impossible to verify the validity of a policy created for a certain site by manual desk check, Checking with the system was difficult in terms of cost.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments to which the invention is applied will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a functional configuration of an autonomous computing device according to an embodiment of the present invention. As shown in FIG. 1, the autonomous computing device 100 according to the present embodiment is a computer system that is an autonomous computing environment including servers 1001, storage devices 1002, and network (N / W) devices 1003. And a communication line such as a LAN (Local Area Network), etc., and the status of each device can be monitored via this communication line. The autonomous computing environment is an environment to which the autonomous computing technology in the present embodiment is applied.

  The servers 1001 described above are various servers such as a Web server, an AP server, and a DB server, and the storages 1002 are devices that can record information such as a DB. The network device 1003 is a communication network such as a LAN that connects the servers 1001 and the storage devices 1002.

  The monitoring device 101 appropriately acquires monitoring data from each node of the servers 1001, the storage devices 1002, and the network devices 1003. An example of monitoring contents is shown below. From the servers 1001, data indicating CPU utilization, data indicating memory usage, resource usage data such as network flow rate and disk access count, log data indicating processing history of each server, and the like are acquired as monitoring data. In addition, the monitoring apparatus 101 acquires data such as a disk usage amount and a disk cache hit rate from the storages 1002 as monitoring data. Further, the monitoring apparatus 101 acquires log data indicating the flow rate of these communication lines and the presence or absence of a communication error as monitoring data from the network apparatus 1003. In addition, when a failure occurs in each node, the monitoring device 101 acquires the failure occurrence as monitoring data.

  The monitoring apparatus 101 generates event information indicating the state of the autonomous computing environment based on the acquired monitoring data, and stores the event information in the monitoring result database 102.

  In addition, the monitoring apparatus 101 appropriately monitors the configuration of the autonomous computing environment, generates the result as configuration information, and stores it in the policy management database 105.

  The policy management database 105 stores policies in addition to the configuration information described above. A policy is data indicating guidelines regarding the operation of the autonomous computing environment.

  The analysis unit 103 acquires event information stored in the monitoring result database 102, generates event information indicating a transition history of state changes in the autonomous computing environment from the past, and changes in the value of the acquired event information And event history indicating the predicted contents of the future state change of the autonomous computing environment are generated by comparing the change history of the value of the past event information.

  When the event information is acquired from the analysis unit 103 or the monitoring result database 102, the determination unit 104 acquires the current configuration information and policy corresponding to the event information from the policy management database 105, and changes the configuration of the autonomous computing environment. A configuration change request, which is request information, is generated and output to the schedule unit 108. If new event information generated by the simulation unit 110 described later does not satisfy the acquired policy, a configuration change request is generated again based on the new event information and the policy.

  The event information storage database 109 sequentially acquires the configuration information stored in the policy management database 105 and manages the history of the configuration information.

  The scheduling unit 108 schedules the configuration change so that the configuration change process is completed by the deadline in consideration of the time required for the configuration change of the computer system that is an autonomous computing environment.

  The simulation unit 110 simulates the scheduling result by the scheduling unit 108 and outputs new event information for the scheduling result. Regardless of the method, the simulator calculates the resource usage rate, application response time, and system throughput in consideration of transient phenomena such as system configuration and resource load information at a certain time in the future. Realize simulation of system behavior including state.

  When the new event information satisfies the policy, the provisioning device 107 executes provisioning processing for the autonomous computing environment according to the scheduling result by the scheduling unit 108 at that time.

  FIG. 2 is a block diagram illustrating a hardware configuration of the autonomous computing device 100. The CPU 201 comprehensively controls each device and controller connected to the system bus. The ROM 203 or the HD 207 records a basic input / output system (BIOS) or an operating system program that is a control program of the CPU 201, a program for the processing shown in FIGS. 3 to 5 executed by the autonomous computing device 100, and the like. ing.

  In the example of FIG. 2, the hard disk (HD) 207 is configured to be arranged inside the autonomous computing device 100, but as another embodiment, a configuration corresponding to the HD 207 is the configuration of the autonomous computing device 100. It is good also as a structure arrange | positioned outside. For example, the program for performing the processing illustrated in FIGS. 3 to 5 according to the present embodiment is recorded on a computer-readable recording medium such as a flexible disk (FD) 206 or a CR-ROM, and is supplied from the recording medium. It is good also as a structure which may be supplied via communication media, such as the internet.

  The RAM 202 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program necessary for execution of processing into the RAM 202 and executing the program.

  The disk controller 205 controls access to external memories such as the HD 207 and the FD 206. The communication IF controller 204 is connected to the Internet or a LAN, and controls communication with the outside by, for example, TCP / IP.

  The display controller 208 controls image display on the display 209.

  The KB (keyboard) controller 210 receives an operation input from the keyboard (KB) 211 and transmits it to the CPU 201. Although not shown, in addition to the keyboard 211, a pointing device such as a mouse can also be applied to the autonomous computing apparatus according to the present embodiment as a user operation means.

  Also, the monitoring device 101, the analysis unit 103, the determination unit 104, the schedule unit 108, the simulation unit 110, and the provisioning device 107 in FIG. 1 are recorded in, for example, the HD 207 and loaded into the RAM 202 as needed This is a configuration corresponding to the CPU 201 to be executed.

  The policy management database 105, the monitoring result database 102, and the event information accumulation database 109 in FIG. 1 have a configuration corresponding to a partial storage area in the HD 207, for example. The policy management database 105 and the monitoring result database 102 may be provided outside the autonomous computing device 100.

  FIG. 3 to FIG. 5-2 are flowcharts showing the operation flow of the autonomous computing device 100 according to the present embodiment.

  First, in FIG. 3, the monitoring apparatus 100 first acquires monitoring data from each node of the autonomous computing environment, and generates event information related to a resource state change or the like from the acquired monitoring data (step S301).

  Subsequently, the monitoring apparatus 101 accumulates the generated event information in the monitoring result database 102 (step S302).

  Subsequently, the analysis unit 103 acquires event information from the monitoring result database 102, and generates or acquires event information indicating a transition history of state change of the autonomous computing from the past based on the acquired event information. The event information indicating the predicted contents of the future state change of the autonomous computing environment is generated by collating the change of the value of the event information with the change history of the value of the past monitoring data (step S303). Future state changes are predicted by applying various analysis methods to changes over time in event information from the past to the present. For example, when the current CPU usage rate is 40% and the CPU usage rate has increased by 10% every 30 minutes from the past to the present, the future CPU usage rate is calculated using linear prediction, and the current CPU usage rate is 4 It is predicted that the CPU utilization rate will exceed the threshold value of 80% after a time. Of course, methods other than linear approximation can be used depending on the type of event and the degree of change.

  Subsequently, the determination unit 104 acquires a policy corresponding to the event information output from the analysis unit 103 or the monitoring result database 102 and the current configuration information from the policy management database 105. Then, the determination unit 104 generates a configuration change request based on the event information, the policy, and the current configuration information (Step S304). Details of the configuration change request generation processing will be described later.

  Subsequently, the scheduling unit 108 performs scheduling processing based on the configuration change request output from the determination unit 104 (step S305).

  Subsequently, in FIG. 4, the simulation unit 110 simulates the schedule output from the schedule unit 108 and outputs new event information as a simulation result (step S306).

  Subsequently, the determination unit 104 determines whether or not the event information output from the simulation unit 110 satisfies the policy (step S307). If the event information does not satisfy the policy, the determination unit 104 newly generates a configuration change request so as to satisfy the policy (step S308).

  Subsequently, the scheduling unit 108 performs a scheduling process based on the newly generated configuration change request (step S309). Then, the process returns to step S306, and the simulation unit 110 performs a simulation for the schedule output here. The processes in steps S306 to S309 described above are repeatedly executed until it is determined in step S307 that the simulation result satisfies the policy.

  If it is determined in step S307 that the newly generated event information satisfies the policy, the provisioning device 107 performs the configuration change process according to the feasible schedule finally generated by the scheduling unit 108. This is executed for the environment (step S311).

  FIG. 6 is a diagram illustrating an example of an autonomous computing environment to be monitored in the present embodiment. Here, an example of a computer system in which a Web server 1 that is a server group 1001, an AP server 1, and DB servers 1 and 2, and a DB that is a storage group 1002 are connected to each other via a communication line that is a network device 103 is taken as an example. Are listed. Note that AP servers 2 to 5 in FIG. 6 are similarly connected to the communication line, but are not in operation, and are spare servers that are added to the computer system as necessary. ing. Further, these spare AP servers 2 to 5 are not only added as AP servers, but are added as necessary, such as servers that provide other services, such as Web servers and DB servers. In FIG. 6, hardware resources such as a server are illustrated for convenience of explanation, but not only hardware but also a set of platforms such as network settings, middleware, and development environments can be handled in the same manner in an autonomous computing environment. Needless to say.

  FIG. 7 is a diagram illustrating configuration information when the autonomous computing environment illustrated in FIG. 6 is a monitoring target. As shown in FIG. 7, the configuration information includes, for example, date / time information, the name of each server (node), service name, role, specification, and status. The date / time information indicates the date / time when the configuration information was generated by the monitoring apparatus 101. The service name indicates the service name of the corresponding computer system. The role indicates the role of the server in the computer system. The status indicates whether or not the server is in an operating state. The above-described configuration information is an example for performing this embodiment. For example, instead of managing whether or not the corresponding server is operating by status, managing the server, service, role, specification, etc. with blank items manages that the corresponding server is not in operation. Of course it is good.

  FIG. 8 is a diagram conceptually illustrating an example of a configuration of event information acquired by the determination unit 104. Therefore, it is actually expressed in a programming language so that the computer can understand it. The same applies to other diagrams relating to the structure of event information. FIG. 8 illustrates two pieces of event information. The event information includes date / time information, occurrence location, and contents. The date / time information is information indicating the date / time when the monitoring data was acquired by the monitoring apparatus 101 or information indicating the date / time when the event information was generated by the analysis unit 103. The occurrence location is information indicating the acquisition location of the monitoring data. The content is information indicating the content of event information analyzed based on the monitoring data. Here, it is shown that the content of the event information 1 is “CPU usage rate per one (AP server) is 70% after 2.5 hours”. The event information 1 is generated by the monitoring device 101 and acquired by the determination unit 104.

  FIG. 9 is a diagram conceptually illustrating an example of a policy configuration corresponding to the event information illustrated in FIG. Here, the policy related to the service A and the AP server where the event information 1 is generated is selected, and among them, the policy 1 indicating the criterion of the optimum CPU usage rate is selected.

  The policy includes application points and rules. The application location is information indicating a location to which the policy is applied. The rule is information indicating a rule that is an application location of the policy. As shown in FIG. 9, it is shown that the application location of policy 1 is the AP server of the computer system that provides service A. Further, the policy 1 rule indicates that “the CPU usage rate per unit is limited to about 40%”. In FIG. 9, the rules are expressed in a document for explanation, but in actuality, they are written in the if / then format often used in computer programming languages so that the computer can determine the rules. The same applies to other diagrams relating to policy configuration.

  Next, a configuration change request generation method in the determination unit 104 in step S304 in FIG. 3 will be described in detail. First, the determination unit 104 acquires current configuration information, and selects a policy as described above. Next, the determination unit 104 applies the acquired current configuration information and policy to the formula for calculating the load amount required for the entire AP server for the operation of the service A shown in FIG. The required load amount is calculated. Specifically, it will be described later with reference to FIG. In this example, the CPU performance ratio and CPU utilization of the AP server are used as the load amount, but other values such as the access amount to the service A may be used. The CPU performance ratio is an index representing the performance of the CPU, and is calculated using values such as a clock frequency and a benchmark test result.

  Next, the calculation processing of the load amount required for the entire AP server to operate the service A will be specifically described with reference to FIG. For example, the determination unit 104 grasps from the acquired current configuration information that the AP server that provides the service A has a single configuration. Further, when the event information 1 shown in FIG. 8 is acquired, the determination unit 104 grasps that the CPU usage rate per AP server after 2.5 hours is 70%. Therefore, as shown in FIG. 11, the sum of CPU performance ratio × CPU utilization for one AP server is calculated. Here, a case where the CPU performance ratio of the AP server is 1 is illustrated, but the present invention is not limited to this.

  Next, the AP server configuration required to satisfy the policy in the operation of the service A based on the load amount of the entire AP server for the operation of the service A and the selected policy calculated by such processing. Is calculated. Specifically, the load amount (70%) after 2.5 hours is set to “suppress the CPU usage rate per (AP server) to about 40%” in the policy shown in FIG. Divide by 40%. When the determination unit 104 performs this process, the number of AP servers necessary to satisfy the policy and operate the service A is calculated. If it is not divisible, the advanced value is set as the required number of AP servers.

  FIG. 12 is a diagram illustrating a method for calculating the necessary number of AP servers by the determination unit 104. As shown in FIG. 12, the necessary number of AP servers is calculated by dividing the load amount of the entire AP server required for providing the service A by the CPU usage rate 40% per unit indicated in the policy. The number of AP servers required after 5 hours is calculated as two.

  FIG. 13 is an example of a conceptual diagram illustrating a configuration change request generated by the determination unit 104 performing the above-described processing. The configuration change request 1 in FIG. 13 corresponds to the estimated load amount after 2.5 hours, such as “2 AP servers for service A will be configured by 2:30, April 4, 2008”. Thus, the configuration change request 1 in which the number of AP servers necessary to satisfy the policy shown in FIG. 9 and provide the service A is generated.

  FIG. 14 is an example of a conceptual diagram showing a schedule that the schedule unit 108 outputs based on the configuration change request 1. Below, the specific example of step S305 of FIG. 3 is demonstrated. Here, the number of AP servers is set to 1 by 2008/4/4 2:00 (configuration change c), and the number of AP servers is 4 by 2008/4/4 4:00 (configuration change b). Is already scheduled. In FIG. 14, in consideration of the time required for the configuration change, in order to complete the configuration changes c and b by the above deadline, it is shown as a schedule that the configuration change is started 30 minutes before those deadlines. ing. For such scheduling, the time required for the corresponding configuration change (job) is used. That is, the configuration change is scheduled so that the configuration change is started at a time traced back by the time required for the configuration change from the configuration change deadline. By doing so, it is possible to perform appropriate scheduling that can reliably complete the configuration change by the deadline. The process for determining the time required for the configuration change will be described in detail with reference to the flowchart of FIG.

  If the schedule unit 108 inputs the above configuration change request 1 in this state, the time required for the configuration change is taken into account in order to reduce the number of AP servers to 2 by 2008/4/4 2:30 (configuration change a). Then, as shown in FIG. 14, it is scheduled to start the configuration change a at 2008/4/4 2:00 30 minutes before the deadline (2008/4/4 2:30).

  FIG. 15 is a diagram showing simulation results for the schedule shown in FIG. Below, the specific example of step S306 of FIG. 4 is demonstrated. The simulation unit 110 outputs new event information as simulation results for the response time of service A every 30 minutes and the CPU usage rate of the service A AP server every 30 minutes. In the example of FIG. 15, when the system configuration is changed according to the schedule shown in FIG. 14, the CPU utilization rate of the AP server is 30% and the response time of service A is 2 at 4:30, 2008/4/4 Second, 2008/4/4 2:00, AP server CPU utilization is 20%, service A response time is 2 seconds, 2008/4/4 2:30, AP server CPU utilization The rate is 20% and the response time of service A is 2 seconds. By 2008/4/4 3:00, the CPU usage rate of the AP server is 50% and the response time of service A is 10 seconds. The result is output. Further, both FIG. 15 (simulation result) and FIG. 8 (event information) show “where and at what time and in what state”, and therefore both are synonymous.

  In the simulation result shown in FIG. 15, since the CPU usage rate of the AP server at 4/3/2008 is 50%, the policy shown in FIG. 9 is not satisfied. Therefore, in step S307 in FIG. 4, it is determined that the policy is not satisfied. In the simulation result shown in FIG. 15, the number of AP servers at 2008/4/4 3:00 is two, and the CPU utilization rate per AP server is 50%. Therefore, as shown in FIG. 16, the determination unit 104 calculates the sum of CPU performance ratio × CPU usage rate for two AP servers.

  Next, based on the load amount of the entire AP server related to the operation of the service A and the selected policy calculated by such processing, the AP server required for satisfying the policy in the operation of the service A is determined. Calculate the number. Specifically, the load amount (100%) of the entire AP server required for providing the service A at 2008/4/4 3:00 is the policy “shown in FIG. Divide by 40% of (AP server) Keep CPU utilization per unit to about 40%. When the determination unit 104 performs this process, the number of AP servers necessary to satisfy the policy and operate the service A is calculated again.

  FIG. 17 is a diagram illustrating a method for calculating the necessary number of servers by the determination unit 104. As shown in FIG. 17, the required number of servers is obtained by dividing the load amount of the entire AP server required for providing service A by the CPU utilization rate of 40% per unit indicated in the policy. The number of AP servers required at 4/4 3:00 is calculated as 3.

  FIG. 18 is a diagram illustrating a configuration change request generated by the determination unit 104 performing the above-described processing. Here, a specific example of step S308 in FIG. 4 will be described. The configuration change request 2 in FIG. 18 includes a simulation result as of April 4, 2008 at 3:00, such as “3 AP servers for service A will be configured by 3:00, April 4, 2008”. In response, a configuration change request 2 in which the number of AP servers necessary for providing the service A with the policy shown in FIG. 9 is described is generated.

  FIG. 19 is a diagram showing a schedule output by the schedule unit 108 based on the configuration change request 2. Here, the specific example of FIG.4N step S309 is demonstrated. By the above-described scheduling process, the number of AP servers is set to 1 by 2008/4/4 2:00 (configuration change c) and the number of AP servers is set to 2 by 2008/4/4 2:30 (configuration change a). ), 4/4/2008 It is assumed that the number of AP servers is changed to 4 (configuration change b). In FIG. 19, in consideration of the time required for the configuration change, in order to complete the configuration changes c, a, and b by the above deadline, it is a schedule to start the configuration change 30 minutes before those deadlines. It is shown.

  When the schedule unit 108 inputs the above configuration change request 2 in this state, the number of AP servers is set to 3 by 2008/4/4 3:00 (configuration change d). Then, as shown in FIG. 19, it is scheduled to start the configuration change d at 2:30, 2008/4/4, 30 minutes before the deadline (2008/4/4 3:00). Also in the scheduling process, the time required for the configuration change is determined in the same manner as in step S305 described above, and scheduling is performed using the determined time required for the configuration change. As for the subsequent processing, as described above, the process returns to step S306, and the simulation unit 110 performs simulation for the schedule output here, and generates a configuration change request and determines that the simulation result satisfies the policy. The configuration change request scheduling process is repeatedly executed.

  As described above, according to this embodiment, when the scheduling result of the configuration change of the computer system to be monitored violates the policy, an appropriate computer system is generated by generating a configuration change request that satisfies the policy. Can be operated.

  FIG. 5 is a flowchart showing a method for calculating the time required for the configuration change. Here, a configuration change in which the AP server 4 is excluded from the computer system including the Web servers 1 to 4, the AP servers 1 to 4, and the DB servers 1 to 2 will be described as an example. That is, here, a case will be described in which a configuration change request in which “content” indicating that three AP servers are configured is output from the determination unit 104.

  In FIG. 5, first, the schedule unit 108 sets the configuration change history in the event information storage database 109 at the same configuration as the computer system configured by the Web servers 1 to 4, the AP servers 1 to 4, and the DB servers 1 to 2. To search (step S511).

  Subsequently, the schedule unit 108 determines whether or not a period having the same configuration as the computer system configured by the Web servers 1 to 4, the AP servers 1 to 4, and the DB servers 1 to 2 exists (step S 512). .

  FIG. 20 is a diagram conceptually illustrating an example of a past configuration change history in the event information storage database 109. As shown in FIG. 20, the configuration change history includes the time, the server name of the server, the service name of the server, the role of the server, the specification of the server, the state of the server, the provisioning, for the server corresponding to each record. The method and job ID are recorded. The state of the server indicates whether the server is in a normal state (no change) or in some state for configuration change. The provisioning method indicates processing executed when provisioning is performed.

  In FIG. 20, there are records relating to 11 servers of Web servers 1 to 4, AP servers 1 to 5, and DB servers 1 to 2 for the same date and time. For example, at 2007/2/16 16:00, “Web” is registered as the role of the Web servers 1 to 4, “AP” is registered as the role of the AP servers 1 to 4, and the role of the AP server 5 is “ “free” is registered, and “DB” is registered as the role of the DB servers 1 and 2. This indicates that a computer system composed of Web servers 1 to 4, AP servers 1 to 4, and DB servers 1 to 2 is operating except for the AP server 5 at 16:00 on February 16, 2007. Yes.

  Also, on 2007/2/16 16:10, “Web” is registered as the role of the Web servers 1 to 4, “AP” is registered as the roles of the AP servers 1 to 3, and the roles of the AP servers 4 to 5 are registered. “Free” is registered, and “DB” is registered as the roles of the DB servers 1 and 2. This is because the configuration change that the AP server 4 is excluded from the computer system operating on the Web servers 1 to 4, the AP servers 1 to 4, and the DB servers 1 to 2 at 16:10 on February 16, 2007 starts. It has been shown. Since the status of the AP server 4 is “configuration change” at 2007/2/16 16:20, and the status of the AP server 4 is “configuration change complete” at 16/2/2007 16:30, The configuration change for excluding the AP server 4 indicates that it took 20 minutes from 2007/2/16 16:10 to 2007/2/16 16:30.

  In the example of FIG. 20, the time when the computer system having the configuration of the Web servers 1 to 4, the AP servers 1 to 4, and the DB servers 1 to 2 was operating exists on 1/16/2007 16:00. Therefore, when referring to the configuration change history shown in FIG. 20, the schedule unit 108 has the same configuration as the computer system configured by the Web servers 1 to 4, the AP servers 1 to 4, and the DB servers 1 to 2 in step S <b> 512. It is determined that a certain period exists, and the process proceeds to step S513. On the other hand, if there is no time in the configuration change history that has the same configuration as the Web servers 1 to 4, the AP servers 1 to 4, and the DB servers 1 to 2, the process proceeds to step S <b> 515.

  In step S 513, the scheduling unit 108 changes the same configuration as the “content” of the configuration change request of the job 8 for the computer system configured from each server in the configuration change history determined to have the same configuration time. Search records for.

  Subsequently, the schedule unit 108 determines the “content (three AP servers configuration) of the job configuration change request for the computer system including each server in the configuration change history determined to have the same configuration time. It is determined whether or not there is a record of the same configuration change as “” (step S514). If it is determined that the same configuration change record as the “content (configuration of three AP servers)” of the configuration change request exists, the process proceeds to step S516. On the other hand, if it is determined that the same configuration change record as the “content (configuration of three AP servers)” of the configuration change request does not exist, the process proceeds to step S515.

  In the example of FIG. 20, the AP server 4 is excluded at 2007/2/16 16:10, and a history of three AP servers is registered, so the schedule unit 108 refers to the configuration change history of FIG. In this case, it is determined that the same configuration change record as the “content” of the configuration change request of the job exists in the configuration change history.

  In step S <b> 516, the schedule unit 108 determines whether or not there are a plurality of records of the same configuration change as the “content” in the configuration change history. If it is determined that there are a plurality, the process proceeds to step S518. If it is determined that there are not a plurality (only one exists), the process proceeds to step S517.

  In step S518, the schedule unit 108 employs, as the “time required for the configuration change”, the longest time among the times required for the configuration change determined from a plurality of configuration change records. In addition, as another processing example of step S518, an average value of the time required for the configuration change determined plurally or a 90% Tile value of the time required for the configuration change determined plurally may be adopted.

  On the other hand, in step S515, the schedule unit 108 adopts an initial value as “time required for configuration change”. That is, the schedule unit 108 determines in step S512 that there is no time having the same configuration as the computer system configured by the Web servers 1 to 4, the AP servers 1 to 4, and the DB servers 1 to 2, If it is determined in step S514 that there is no record of the same configuration change as the “content” of the job configuration change request, an initial value (for example, 30 minutes) is adopted as the “time required for the configuration change”.

  In step S517, the schedule unit 108 employs the time required for the configuration change determined from the configuration change record as the “time required for the configuration change”. In the example of FIG. 20, since there is only one configuration change record that is the same as the “content” of the configuration change request for the job, step S517 is executed. That is, 20 minutes is adopted as the “time required for the configuration change” for the job 8. Note that the above-described processing is merely an example in how to obtain “time required for configuration change”. For example, it is needless to say that the processing can be any process that can grasp the time required for the configuration change performed in the past, such as uniquely managing the system configuration before and after the configuration change request and the time required for the configuration change request.
