[0040]
Next, an operation of constructing a business system using registered resources and system information will be described.
FIG. 8 is a diagram illustrating an example of the operation of the system construction.
The system construction unit 300 includes the following units.
When a new business system is constructed on the data center 1, first, as shown in FIG. 8, an application used in the business system is input to the center management computer 8 (60).
The center management computer 8 extracts the system configuration. Specifically, the system construction unit 300 reads out the application database 17, the middleware database 16, and the registered data (resource / system information) by the system configuration automatic extraction unit, and reads the business system from the system database 18. And reads out the data relating to the resource / system information constituting the system, and extracts a new business system configuration (computer, storage configuration) based on the read data (61).
[0041]
Next, the system construction unit 300 uses the system configuration correction unit to execute the system configuration from the viewpoint of cost, performance, resource configuration, and the like. Is partially corrected (62).
The system construction unit 300 of the center management computer 8 re-evaluates the system configuration (performance, cost, etc.) based on the modified configuration of the new business system (computer configuration) by the system configuration re-evaluation means. The system configuration re-evaluation means 57 outputs the result of the execution as a re-evaluation result (63).
The system administrator determines whether or not the system configuration is possible based on the re-evaluation result (64). If it is determined that the system configuration is not acceptable, the system configuration is corrected again by the system configuration correction unit 56 (No in 64).
[0042]
If it is determined that the system can be configured (yes at 64), the system constructing unit 300 searches for unused system resources by the unused computer resource searching unit and the unused storage searching unit 59 that search for unused resources ( 65).
The unused computer resource searching means searches for an unused computer using the computer database 13 of the database 700.
The unused storage search means searches for unused storage using the storage database 14 of the database 700.
[0043]
The system construction unit 300 determines whether there is an unused resource for constructing the system (66). If there is not enough unused resources (No in 66), the system construction unit 300 performs the operations (processes) indicated by 67 to 72 in FIG.
The system construction unit 300 extracts, by the priority adjusting means, computer resources to be cut off from the low priority system (67). The priority adjusting means extracts computer resources of the system having a lower priority based on the priority registered in the system database 18, and adjusts the extracted computer resources.
[0044]
The priority of the system database 18 is registered when the system is constructed. After that, it may be changed based on an instruction from the administrator.
The system construction unit 300 has a priority registration unit that registers a priority. The priority registration means receives an input of the priority of the constructed system from the administrator via the input unit 800, and registers the priority in the system database 18.
[0045]
Based on the above instruction, the system arranging unit 300 corrects a part of the resources to be cut off (corresponding to a reexamination of the cut-off resources) based on the instruction by the resource arrangement readjustment means (68). ).
Specifically, the resource arrangement readjustment unit receives, from the system administrator via the input unit 800, an instruction relating to the detached resources extracted by the priority adjustment unit 61.
The resource arrangement readjustment unit notifies the administrator of the computer resources and the system configuration extracted by the priority adjustment unit, urges an instruction from the administrator, and receives the instruction. The administrator analyzes the notified computer resources and the system configuration, and enables the system administrator to partially correct the surplus resources and the computer resources to be introduced from the low-priority system.
The resource arrangement readjustment unit adjusts resources (computer resources, which may include storage) to be released from the system (business system) already constructed, based on an instruction from the administrator.
The system arranging unit 300 re-evaluates the effects of the modified resources to be released and the system priority based on the priority of the system by the resource arrangement evaluation means, and reports it to the system administrator (69).
[0046]
The system administrator determines whether or not the configuration is possible based on the result of the resource arrangement evaluation means (70). If it is determined that the configuration is not possible (No at 70), the resource arrangement readjustment unit 62 makes a correction again (68, 69).
[0047]
If it is determined that the system can be configured (yes in 70), the system construction unit 300 causes the business system stop procedure execution unit to stop the application running on the computer to be disconnected and the middleware.
[0048]
Next, after the system is stopped by the business system stop procedure executing means 65 (71), the system construction unit 300 deletes the application and the middleware by the business system operating environment deletion means 66, and the computer resources are allocated to the system. The unused computer resources are changed from unused states to unused states (72).
[0049]
When sufficient unused resources for building a new business system are secured, the system building unit 300 determines the basic software of the computer to be used in the system by the starting storage selecting means (73). Next, the operating environment of the business system is built by the business system operating environment building means 68 (74).
Based on the business system constructed by the system construction unit 300, the switch device control unit 500 instructs the switch device 4 to connect the business system computer and the business system storage. The switch device 4 connects the business system computer and the business system storage based on an instruction from the switch device control unit 500.
[0050]
As described above, according to the present invention, when constructing a new system, the operating environment of the system can be automatically constructed using the surplus resources. Further, even if it is not possible to secure sufficient surplus resources to construct a system, it is possible to construct an operating environment of a high-priority system by using resources of a low-priority system.
[0051]
By using a computer resource utilization method for automatically constructing such a system and allocating resources in consideration of priority, for example, even if a failure such as a failure occurs in a part of the system, unused computer resources, Alternatively, an alternative system configuration can be ensured by using computer resources of lower priority.
[0052]
Alternatively, when performance degradation is observed in a high-priority system, the equipment of a high-priority system can be enhanced using unused computer resources or low-priority computer resources.
[0053]
Alternatively, when an overload is observed in a high-priority system, the facilities of a high-priority system can be enhanced using unused computer resources or low-priority computer resources.
[0054]
Alternatively, in a case where maintenance is performed in a high-priority system, an unused computer resource or a low-priority computer resource can be used to secure an alternative facility during maintenance.
[0055]
Alternatively, if there are multiple business systems in the data center with different loads due to online processing during the day and batch processing during the night, systematically cut off low-load computer resource equipment and provide access to a high-load business system. Computer resources can be used efficiently.
[0056]
