I've never liked the jobs that hold the queues or do controlled ends and then wait a bit and then assume everything has finished. Far better to do the holds/controlled ends and then start monitoring. Some sort of process like: 0. Hold job queues/do controlled ends on the subsystems. 1. Delay for a minute or so. 2. Check the subsystems for active jobs. Use Rob's method, other APIs, or WRKACTJOB to a SPLF that you parse. It doesn't really matter. 2a. If none exist, go to step 4. 2b. Otherwise increment a counter. 3. Check the counter. 3a. If the counter < your threshold (say, 30 minutes), go to step 1. 3b. If you require a backup, do a forced end of the jobs/subsystems, monitoring for completion, and go to step 4. 3c. If you don't require the backup, or if you cannot cancel the jobs (as they update critical tables), go to step 5. 4. Do the backup. 5. Release queues/restart subsystems. John A.

For example the api that is like WRKOBJLCK can be used to get a list of jobs that have a lock on the library in question. Then you can proceed to cancel those jobs. We've already held the job queues and since we have a kick a$$ machine it doesn't take long for any batch jobs to have finished. So, all that is left, are some interactive jobs that our routine blows to kingdom come.

Occasionally, a session is left "hanging" out on the system even though there are no active users. This results in a system message that the file is active and the saves are halted until the session can be canceled. Is it possible to check the system prior to running nightly batch jobs and automatically cancel all sessions? -- This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing list To post a message email: MIDRANGE-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/midrange-l or email: MIDRANGE-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/midrange-l. -- This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing list To post a message email: MIDRANGE-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/midrange-l or email: MIDRANGE-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/midrange-l.
