Did you check to see if anyone was in a screen that was trying to use the
records you were trying to run?  We have had several instances of a user
having a record open on an interactive screen and it locks a batch job
waiting for the record to become inactive.

We experienced a problem today that I've not encountered before.  A pick
list print job was running and entered a LCKW state (as shown on
WRKACTJOB) and stayed in that state for a long time.  So long, in fact,
that I ended up ENDJOB *IMMED and then eventually needed to use ENDJOBABN.

What confounds me is that I was unable to determine what resource the job
was waiting on.  When I displayed job record locks, there were none.  I
tried using the WRKOBJLCK from the job's list of locks and besides being
tedious, I was still unable to identify a resource for which the job was
waiting.  I also used WRKACTJOB and scanned the job lists to see if any
other jobs were in an unusual state that might have been causing the
conflict (especially the QDBSRVxx jobs) - and found none.  Finally, I used
DSPLOG to see if the system was reporting any messages like damaged
objects or such - again, nothing reported (I also checked DSPMSG QSYSOPR).
 Interestingly, there were no other user-submitted "batch" jobs running at
the time - so I couldn't blame it on a query building an index!

As soon as the job was ended, other queued jobs which ran the same process
began running and continued without incident.

Does anyone have an idea of what may have been behind this?  Is there
another command or way to see what resources a job is waiting for?
