When I monitor a job in WRKSYSACT, I see that the priority varies from 20 to 23, and once in a while it drops to 10 or 15. What would cause this drop?
The problem that you described is quite normal. Often a task requires a resource that is held by the a higher PTY task, and the lower PTY task has to wait for the higher task to execute and relinquish the resource. This causes the lower PTY task to raise its PTY to the same as the higher PTY task. That's the reason you see the job at PTY 20 running at PTY 10 or 15.
