Run the Control-M Monitor as Non-swappable

Set parameter NONSWAPM to Y in member CTMPARM in order to activate the Control‑M monitor as non-swappable. For more information, see the Control‑M chapter in the INCONTROL for z/OS Installation Guide: Installing.

This causes Control‑M to be paged-in and paged-out according to a more economical algorithm. In addition, this speeds up the paging process by causing some basic address-space related pages to remain in virtual storage. Non-swapping mode ensures good response for the Control‑M monitor, as well as the best overall performance.

If the Control‑M monitor is run as swappable, the Control‑M status tracking task may get stuck waiting for a JES response. This can happen if the monitor communicates with an overloaded JES.
