We are experiencing problem with batch queues taking much longer than they are configured to start background jobs posted.
E.g Fast Queue is configured to execute every second with 2 processes. However, I see the jobs are posted to the queue but takes 2-5 mins to start.
I have reinitialized the queue but still cannot see the difference. Same happens with other queues. What could be the problem and where should I be looking at?
There are no Executing jobs which the queue should be waiting for either.
DBMS Scheduler was crashed today and we had to restart database and enable scheduler.
