CA WA CA 7 Edition programs must OPEN the CA Datacom/AD MUF to access scheduling data. If the MUF is unavailable, some programs simply report the error and they terminate. Other programs periodically retry the OPEN. These programs include:
This section describes the retry behavior of these programs. Consider using this information to write automation procedures to respond when these programs report a MUF outage.
If the MUF is not available, a message is issued beginning with:
CAL2D022E CA Datacom OPEN failed…
A WTOR follows the CAL2D022E message:
CAL2D023R Reply END to stop OPEN retries (end with user 220 abend)
The OPEN is retried every 30 seconds until the MUF becomes available or you reply END to the CAL2D023R prompt.
You see this behavior if the MUF is unavailable during a program initialization. The behavior can also occur during normal processing if the MUF ends unexpectedly.
Most functions of these programs cannot continue without the MUF. If you do not intend to start the MUF, reply END to the outstanding WTOR, and the program terminates.
If you do not reply END, CA7ONL resumes processing when the MUF becomes available. Then, CA7ONL retries transactions that the MUF outage interrupted before continuing normal processing. This process is known as failover processing. Failover status messages are written to the CA7ONL JES job log during this process. Monitor them for a successful completion.
To avoid this behavior, try to ensure that the MUF is available before starting these programs.
