Environment

Release : 9.3

Component : APPLICATIONS MANAGER

Cause

One of the main reasons this error occurs is if the Backlog and History has grown exponentially. This could happen in an environment that has not been used in a long time allowing the Backlog and History to grow into the 1000's or 10,000's.

Resolution

It is recommended that Support is contacted to confirm issue and a back up of the database is taken before running the below statements as the AM Oracle User:

SQL> delete from so_job_queue; 

SQL> truncate table aw_job_queue_activity; 

SQL> update so_job_history set so_status=32, so_status_name='FINISHED' where so_status_name in ('INITIATED','RUNNING','STAGED','STAGED_PW','STARTED','STARTING','QUEUE WAIT','PRED WT HOLD','PRED WAIT','KILLING','DATE PENDING','CONDITN WAIT','AGENT WAIT')

A commit should be done between each statement.
