Is created by the change information management function 601, the target device and the affected device are extracted by the device status management function 602, the device status management table 105 is created, the status of the device is set, and the created change information management table is created. 104 and the device status management table 105 are transferred to the operation terminal 102. The terminal configuration management program 109 running on the operation terminal 102 uses the batch change information management function 604 and the batch device status management function 605 to transfer the change information management table 104 and device status management table 105 transferred from each computer system 101. A composite system change information management table 106 and a composite system device state management table 107 are created based on the above, and are displayed collectively on the operation screen. The operator of the operation terminal 102 refers to the operating configuration identification number 208 and the post-change configuration identification number 209 in the configuration information column 203 of the change information display screen 200 displayed by the batch change information management function 604, and performs the post-change configuration identification. The consistency in the entire complex system is confirmed by checking whether all numbers 209 match (step 802). If the matching is not achieved (step 803 = NO), the above-described operation is performed again by specifying the number 204 that specifies another configuration change.

[Change and Confirmation of Device Status 702] FIG.

On the device status display screen 300 displayed by the collective device status management function 605, the status of the device in use 303 among the target device 301 and the affected device 302 in each computer system 101 is referred to as unused 304. Instruction operation is performed (step 901). When the collective device status management function 605 transmits this instruction to the configuration management program 108 on the corresponding computer system 101,
The received configuration management program 108 changes the designated device to an unused state by the device status management function 602. The operator of the operation terminal 102 refers to the device status display screen 300 to check the status of the target device 301 and the affected device 302 in the entire complex system (step 902), and all devices are unused 304 in the entire complex system.

Send instructions all at once. After this, the operator of the operation terminal 102
The progress of the configuration change is monitored with reference to the progress status 202 on the change information display screen 200 (step 1002).
If the configuration change is interrupted due to the occurrence of a failure during the change execution (step 1003 = YES), the configuration change function 603
Sends a message to the operation terminal 102, and the message is displayed on the change information display screen 200 as a message 210. Therefore, the operator of the operation terminal 102 checks the cause of the failure with the message 210 (step 1004), and based on the contents, It is determined whether the configuration change can be continued (step 100).
5). If it is determined that continuation is possible, the cause of the failure is removed (step 1006), and then continuation of the configuration change is instructed (step 1007). If the configuration change cannot be continued, a recovery procedure (step 1100) is executed. When the change of the configuration 1 (205) is completed, a similar change instruction and progress monitoring are performed for the configuration 2 (206) and the configuration 3 (207) (step 100).
8).

[Configuration Recovery 704] FIG. 11 is a flowchart showing the operation procedure of the configuration recovery in FIG. FIG.
In the case where the configuration change is interrupted due to the occurrence of a failure during the execution of the configuration change described above and the configuration change cannot be continued, the operator of the operation terminal 102 checks the content of the progress 203 on the change information display screen 200. Check the break point. Then, the interruption point is the configuration 2 (206) or the configuration 3 (20
7), the previous configuration (Configuration 1 (205)
Alternatively, if there is a change in the configuration 2 (206) that has already been completed normally (step 1101 = Y)
ES), the operator gives an instruction to the configuration information that all the configurations should be restored from the post-change configuration 209 to the operation configuration 208 in the same order as when the configuration change was executed (step 1102). Then, it is confirmed on the change information display screen 200 that the recovery of the configuration information has been completed (step 1103). The above recovery operation is performed for all the configuration information whose change has been completed (step 11).
04). Thereafter, the operator instructs that the configuration information whose configuration change has been interrupted due to the occurrence of a failure should be restored to the original operating configuration 208 (step 1005), and refers to the change information display screen 200 to execute all recovery processing. The completion is confirmed (step 1006).

[0026]

As described above in detail, according to the composite system configuration change method of the present invention, the first, second, third, and fourth configuration change management steps are sequentially executed. With reference to the batch display of the operation screen in the operation terminal for device configuration change, whether the content of the configuration change to be implemented is consistent for the entire complex system,
While confirming in real time how much the configuration change is progressing for the entire complex system, it is possible to perform collective operation for changing the device configuration of the entire complex system via the same operation screen.

Further, since the first, second, third, and fourth device status management steps are sequentially executed, the composite system is referred to by referring to the batch display of the operation screen on the operation terminal for changing the device configuration.
