Establishing maintenance procedures

Running IMS utilities on a regular, prescribed basis is one of the main tasks for maintaining IMS. Maintaining IMS might also involve additional tasks such as reorganizing databases and installing service regularly.

Maintaining IMS might involve the following activities (done manually or automated):

Running reports, analyzing the reports, and taking action based on the analysis
Reorganizing databases on a regular basis
Performing preventive maintenance on the message queues
Running IBM-supplied or vendor-supplied tools on a regular basis
Installing service on a regular basis
Running IMS-supplied utilities on a regular basis

The frequency with which utilities are run is an installation-dependent decision.

Tip: You can determine the current maintenance level of your IMS system by using the /DIAGNOSE SNAP MODULE(modname) command.
