If each CPU is fully controlled by its Control‑M system, only one CMEM subsystem is required on each CPU. The CMEM that is part of Control‑M system A runs on CPU A. The CMEM that is part of Control‑M system B runs on CPU B.
However, if each Control‑M system must acknowledge events that might occur under both CPUs, each CPU must operate two CMEM subsystems (one for Control‑M system A and the other for Control‑M system B). However, a job can be handled only by one CMEM subsystem.
The following table shows the number of CMEM subsystems needed for handling events:
