RE: CPU utilization high daily at specific time



fixed

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.

Hello, All:

One of the iSeries systems in our configuration usually has relatively

low (30-50%) utilization during the early morning.  However, recently 
we have had daily occurrences of near 100% utilization (sustained for 
about
30-45 minutes) at between 5AM and 6AM.  We strongly suspect that this 
is the result of some query being issued by a scheduled job on some 
other server.  We would like to identify either the job or (Ideally) 
the SQL statements that are being executed under these circumstances.
 
This is causing an impact to that system's ability to quickly process 
data coming from MQ during that time period, which is a very bad thing

in this case.
 
Can any of you give some idea what we might do to identify the job or 
user, and potentially the exact statement that is causing this 
performance hit?  Or maybe some other information I need to provide in

order to arrive at an answer?
 
Thank you,
