Specifically, the application resource management unit 120 transfers the distribution data 121 to the managed server computers 410 and 420, respectively. Then, the application resource management unit 120 remotely operates the managed server computers 410 and 420 to perform the expansion process of the transferred distribution data and the setting of the operating environment after the expansion.
- the operating environment of the server application is unified for each server computer belonging to the server group. Therefore, when a new server computer is added to the server group, it is necessary to construct the same operating environment as that of the existing server computer.
- FIG. 13 is a diagram showing an addition status of the managed server computer to the server group.
- the Web server group is controlled by the site management server computer 100.
- the managed server computer 450 in the server pool 33 is added to the loop 31.
- the managed server computer 450 is installed with a program and data for functioning as a Web server.
- the server addition process will be explained in detail below.
- FIG. 14 is a diagram showing server addition processing.
- the administrator operates the operation management client computer 200 and inputs an additional command for the server computer. Then, the operation management client computer 200 issues a server computer addition instruction to the site management server computer 100 (step S61).
- the addition instruction is received by the system resource management unit 110 of the site management server computer 100.
- the system resource management unit 110 outputs a server addition event related to the server group to the application resource management unit 120 (step S62).
- the application resource management unit 120 performs a process for checking the freshness of the collected image data (step S63).
- the latestness of the image data can be determined by, for example, acquiring the date and time when the image data was collected and determining whether or not the application resource update processing has been performed after that date and time.
- the application resource management unit 120 If it is determined that the image data is not up-to-date during the latestness check process, the application resource management unit 120 returns an error to the system resource management unit 110. Then, the system resource management unit 110 transmits an error message to the operation management client computer 200. This completes the server addition operation.
- the system resource management unit 110 issues an installation instruction to the managed server computer 450 and the domain management server computer 310 to be added via the server control unit 130 (step S64).
- the image collection processing unit 311 receives an installation instruction. Then, the image collection processing unit 311 executes the image data installation process (step S65). Specifically, image data is installed according to the following procedure. First, the system resource management unit 110 shuts down the OS of the target managed server computer 450 by remote control. Next, the image collection processing unit 311 installs the image data stored in the image data storage unit 312 in the hard disk device of the managed server computer 450. Further, the system resource management unit 110 restarts the managed server computer 450.
- activation suppression processing of the server application 452 is performed prior to the collection processing. That is, a copy of the image data is created in a state where activation of the server application is suppressed. Therefore, even when the image data is restarted after being installed on the managed server computer 450, the server application 452 is prevented from being started, and the server application 452 is not started.
- the system resource management unit 110 outputs an event after image collection via the image collection processing unit 311 (step S66).
- the post-image collection event is received by the resource management agent 451 of the managed server computer 450.
- the resource management agent 451 releases the start suppression of the server application 452. Further, the resource management agent 451 performs the expansion processing of the crawling material and the rewriting process of the unique information (IP address, etc.) of the managed server computer 450 (step S67).
- the system resource management unit 110 outputs a distribution start instruction to the added managed server computer 450 to the load balancer 320 (step S68). Further, the system resource management unit 110 outputs a server addition event to the application resource management unit 120 (step S69). In response to the server additional event, the application resource management unit 120 adds information about the newly added managed server computer 450 to the information of the server group managed by the application resource management unit 120 (step S70).
- the managed server computer can be added to the server group.
- an arbitrary managed server computer can be deleted from the server group, and the managed server computer can be returned to the server pool 33.
- FIG. 15 is a diagram showing processing for deleting a managed server computer from a server group. is there.
- the administrator inputs an instruction to delete the managed server computer from the server group to the operation management client computer 200.
- a server deletion instruction is issued from the operation management client computer 200 to the site management server computer 100 (step S81).
- the server deletion instruction is received by the system resource management unit 110 of the site management server computer 100.
- the system resource management unit 110 outputs a pre-server deletion event to the application resource management unit 120 (step S82).
- the application resource management unit 120 deletes information about the specified managed server computer from the list of managed server computers in the server group (step S83).
- the system resource management unit 110 moves the duplication to which the designated managed server computer belongs to the server pool (step S84). Thereafter, the system resource management unit 110 outputs an event after server deletion to the application resource management unit 120 (step S85). As a result, the application resource management unit 120 recognizes the completion of the deletion processing of the managed server computer from the server group.
- IP address and other specific information are set when building the environment for the managed server computer. The unique information setting process will be described in detail below.
