Deactivating the CMEM Facility

Under normal circumstances, the CMEM monitor is not shut down. However, CMEM shutdown may be necessary for the following reasons:

• to resolve a problem that cannot otherwise be resolved

  In this case, the monitor must be immediately restored to minimize the impact of the shutdown on the work environment.

• to clean up (erase) all loaded CMEM tables from memory, or stop all CMEM functionality (for example, for a system shutdown)

To stop and immediately restart the CMEM facility, replace the active CMEM monitor by starting a new CMEM monitor. For more information, see Replacing an Active CMEM Monitor.

When the monitor replacement method is not applicable, and a complete shutdown is required, issue one of the following operator commands:

CMEM shuts down after a few minutes.

CMEM rules are never triggered for dataset events and step termination events caused by jobs that start when CMEM is down.
