Shutting Down the Control-M Monitor

To shut down the Control‑M monitor, use the P CONTROLM operator command.

After a few seconds (up to a minute), the Control‑M monitor shuts down and the following messages are displayed on the operator console:

In case of emergency, you can cancel the Control‑M monitor. However, you should avoid doing this unless absolutely necessary, because cancelling the monitor may corrupt the database in the Active Jobs file, Conditions file, and Log file. There are times when cancelling the Control-M monitor is unavoidable (for example, when there are severe problems in JES). However, in such cases, BMC recommends that the user first try to QUIESCE Control-M, if possible. In this way, you can minimize the activity taking place within Control-M before the cancellation, and thereby minimize the potential for corruption.

When canceling the monitor, as in the case where the Control-M monitor is hung, a system (SVC) dump of the Control-M Monitor address space should be taken. To do this:

1. Enter MVS console command 'DUMP'
2. Specify JOBNAME or ASID of the monitor
3. Specify parameter SDATA=(CSA,GRSQ,SUM,RGN,TRT)

The SVC dump should be taken before trying to stop/cancel the Monitor.

When you shut down the Control‑M monitor, all other Control‑M facilities (for example, CMEM), IOA Online monitors, and Online facility sessions can remain active.
