Activating the CMEM Facility

It is recommended that CMEM be active in every computer in the data center (not just in the computer where the Control‑M monitor is working). However, it is possible that in your data center CMEM does not operate in all the computers. (This option is controlled by the Control‑M installation parameters.)

The CMEM monitor must operate 24 hours a day. The usual way to ensure this is to automatically initialize the CMEM monitor during the IPL process. For more information, see the Control‑M chapter in the INCONTROL for z/OS Installation Guide: Installing. To activate the CMEM Subsystem manually, use the operator command

S CTMCMEM

The same operator command can be used to activate the CMEM monitor manually.
