The Control‑M monitor usually operates 24 hours a day as a started task (STC). Usually the monitor is automatically activated as part of the IPL process. To activate the monitor manually, use the operator command
S CONTROLM |
If the monitor is successfully activated, the following message is displayed on the operator console:
CTM100I CONTROL‑M MONITOR STARTED |
When Control‑M operates in standalone mode, once the Control‑M monitor is active, if you try to activate an additional Control‑M monitor with the same IOA components in the same computer environment where a Control‑M monitor is active, the new (that is, additional) monitor immediately shuts down and an appropriate message is issued.
It is possible to activate more than one Control‑M monitor in the same computer environment (for example, PROD and TEST version) by defining a different IOA environment (and a different QNAME) for each monitor. For more information see the Control‑M chapter of the INCONTROL for z/OS Installation Guide: Installing.
Under CTMPLEX configuration, more than one Control‑M can be active under an IOA environment. For more information about Control‑M in CTMPLEX configuration see CTMPLEX: Control-M for the Sysplex.
You can issue Control‑M operator commands that are executed immediately when you start the Control‑M monitor. You do this by specifying the operator command in parentheses as the fourth positional operator in the START command.
Example: Activate the Control-M monitor in QUIESCE mode by issuing the following command:
S CONTROLM,,,(QUIESTIME=NOW)
No jobs will be submitted by Control-M until you issue the QUIESTIME=OFF command.
Example: Activate the Control-M monitor in QUIESCE mode and simultaneously instruct Control-M to skip the next NEWDAY process (see Special Newday Parameters.) by issuing the following command:
S CONTROLM,,,(QUIESTIME=NOW),NEWDAY=SKIP
No jobs will be submitted by Control-M until you issue the QUIESTIME=OFF command.
