After waiting for a predetermined time, it refers to the time storage unit 12 and checks whether the activation of the application software or the OS to be monitored has been completed (step B5). If it has been started normally, the fact that it has been started normally is output to the output device 3 in the restart after replacement of the load module (step B8). If it has not been started normally, the load module is replaced. In order to return to the previous state, the process of the evacuation load module restoration means 24 is started (step B7).

Finally, the evacuation load module recovery means 2
4 will be described with reference to the flowchart shown in FIG. First, the save load module restoration unit 24 outputs to the output device 3 that the startup has failed in the restart after the replacement of the load module (step C1 in FIG. 4). Next, the load module in the save load module group 15 is replaced with the corresponding load module in the software load module group 14 to return to the state before the replacement with the corrected load module (Step C2). Finally, the application software or the OS to be monitored is restarted (step C3).

The time storage unit 121 and the standby time storage units 131 to 13n
Are allocated to the storage device 1 shown in FIG.

The start-up processing section 200 divides the start-up processing into several processing units (start-up processing STEP1 to start-up processing S
TEPn), before and after each processing STEP, includes monitoring start time registration means # 1 to #n (211 to 21n) and monitoring end time registration means # 1 to #n (221 to 22n). Each of the monitoring start time registration units # 1 to #n is stored in the time storage unit 121.
The start processing start time before the processing of each of the start processing STEPs 1 to n and the information indicating that the start processing has been completed after the processing of each of the start processing STEPs 1 to n by the monitoring end time registration means # 1 to #n. It is memorized. Standby time storage units # 1 to #n
(131, 132 to 13n) include a start processing STEP1.
To n are stored in advance.

Each of the above-mentioned processing means generally operates as follows. When the start processing of the monitoring target application software or OS starts, the start processing unit 2

31 is started. The activation processing unit 200 thereafter performs the processing of the activation processing STEPn, and when the processing is completed, the monitoring end time registration means #n (22n)
Information indicating that the processing of the processing STEPn is completed is registered in the time storage unit 121. Monitoring start time registration means #n
The activation monitoring unit 231 that has started the processing in (21n)
It waits until the standby time stored in the standby time storage unit #n (13n) elapses from the time stored in the time storage unit 121. After the elapse of the standby time, the time storage unit 121 is referred to again to determine whether or not the activation processing STEPn has been completed. If the activation has failed, the load module is restored. Since it is difficult to calculate the standby time in total with the system configuration and the startup of complicated software, a more appropriate standby time is monitored by monitoring in fine processing steps as in the embodiment shown in FIG. It becomes possible to monitor by time.

[0019]

As described above, according to the present invention, since the startup is monitored at the restart after the replacement of the modified load module, the number of steps of the startup confirmation work after the replacement with the modified load module can be reduced. . For example, when the replacement of the corrected load module is performed on multiple computers at the same time, or when it is not possible to confirm the startup immediately due to business reasons, the startup of each computer is checked one by one at the next startup of the software to be monitored. No need,
The determination can be made by referring to the result automatically output by the activation monitoring unit 23 or the evacuation load module restoration unit 24. In addition, startup monitoring is performed, and when a failure is detected, the system automatically recovers to the state before replacement with the modified load module. And the burden on the user or maintenance person is greatly reduced. Furthermore, by managing the time monitoring of the startup processing in smaller processing step units, monitoring can be performed with a more appropriate standby time.
