Select this step to allocate and format communication files in a non-Sysplex environment where the MVS System Logger will not be used. For more information, see CMEM considerations.

The FORMSUB2 job allocates and formats a file that enables the Control‑M Event Manager or Control‑O monitors to communicate with the Control‑M monitor.

Note: If you already performed this job for Control-M, do not perform it again for Control-O.

All actions specified below should be repeated for each computer in the computer list.

The disk on which such a file is to be allocated must have the following characteristics:

• CMEM (or Control‑O) in the designated computer must have WRITE access to the file.
• The Control‑M monitor must have READ access to the file.
• The disk must not be busy, and should not be reserved from any computer in the complex. Otherwise, there might be serious performance degradation in CMEM and in the Control‑M monitor.

For each computer whose SYSID was specified in IOACPRM, take the following steps:

1. Change the SMFID parameter to match the related entry.
2. Change the VOL and UNIT parameters to define a disk suitable for the specified SMFID.
3. Submit the job.

   Note: The job must run in the computer whose file is being formatted during this run.

4. Check for successful completion. All job steps must end with a condition code of 0.

   Note: All communication files should be reformatted whenever a new computer is added to the computer list.

   Verify that the CMEM, Control‑O, and the Control‑M monitors are down when formatting the subsystem communication file.
