PI81356: INCORRECT JOBSTATS CAUSED APPLICATION TO HANG

Fixes are available

APAR status

Closed as program error.

Error description

When a job finishes very quickly, the scheduler is still trying
to update the previous status to record the job status, and
this caused inconsistency because the job has already
completed. This will cause the application to wait to end.

****************************************************************
When a batch job completes very soon after it is dispatched,
there exists a timing window where the update for the 'ended'
status from the endpoint may be overwritten by the 'executing'
status from the scheduler.
Scheduler operations and the Job Management Console will show
the 'executing' status even though the job has finished.
If the job was submitted from the WSGrid client, the client may
hang as it continues to wait for a final status.

Problem conclusion

Additional synchronization has been added to control updates to
the job status table in the job scheduler database. This will
ensure that no timing window exists where job status updates fro
the scheduler and endpoint could overwrite one another.
