The purpose is to improve resource usage efficiency.

[Means to solve the problem]

FIG. 1 is a diagram showing the principle of the present invention.

In FIG. 1, 100 is an information processing system to which the present invention is applied, and 200 is a plurality of resources included in the information processing system 100.

X is long-time use information provided corresponding to each resource 200 according to the present invention.

300 is a setting means provided according to the present invention.

400 is a release means provided according to the invention.

500 is a detection means provided according to the present invention.

600 is a determination means provided according to the present invention.

[Effect]

The information processing system 100 uses a plurality of resources 20 when necessary.
A vacant resource 200 is selected and captured from among 0 resources, and the resource 200 being captured is released when it becomes unnecessary.

The setting means 300 sets each resource 200 at a predetermined period.
The resource 200 is monitored for idle/occupied state, and the long-term use information X corresponding to the resource 200 in the occupied state is set to the occupied state.

When each resource 200 is released, the release means 400 sets the corresponding long-term usage information lx to an empty state.

The detection means 500 is configured so that the setting means 300 receives each long-time usage information 1.
1X, each long-time usage information flX is checked to see if it is empty or occupied, and resources 200 corresponding to the long-term usage information lx set to a busy state are detected.

The determining means 600 counts, for each resource 200, the number of times that the detecting means 500 consecutively detects that each long-time use information It is determined that the resource 200 that has exceeded the limit has been in use for a long time.

Therefore, if the setting means sets the period for setting each long-time usage information and the reference value for determining the counting result by the determining means, the time period in which the information processing system normally uses resources can be significantly longer. It becomes possible to determine that a resource that is in continuous use for a long period of time is a resource that is being held invalidly due to a failure or the like, thereby improving the efficiency of using the resources possessed by the information processing system.
