Thanks for your reply, Wayne.

Unfortunately, as I said, we believe this job to be initiated remotely,
perhaps from a M$SQL server that's gathering data it needs for some
report.

Sorry, I should have been more specific.  Is there some exit program or
other stealth way we can actually drill down to the SQL statement being
executed under these circumstances?  I realize I can see "last SQL
statement executed" within the iSeries Navigator tool, once the job has
been identified, but we'd like this to be a tad more automatic.

Dennis, take a look at scheduled jobs using the WRKJOBSCDE command.  You
  will be able to see the scheduled times of all jobs and isolate the
one that is causing the problem.
