LOL, yes if I can avoid executing the *spendmoney command I think that would be good. I will look into changing the priority of the web jobs and perhaps moving them to their own space. Any ideas on how I can do this and minimize (or avoid) downtime?
Thanks again!

Brian,
These jobs are causing most of your problems. They run at priority 20, the
same as the QINTER jobs. You can throttle them back to run at a lower
priority if your web application will permit it. You can also make them run
in a separate memory pool so that you're not competing with the QINTER or
other batch jobs.
I'd start looking there before engaging the *SPENDMONEY command.

Subject: System Analysis Suggestions
Hi All,
I'm wondering if anyone can suggest a course of action to help determine out
bottlenecks in our AS400 and a plan to improve performance?
A few years ago we upgraded to a 520-9406 machine. However, I have noticed
over the past two years that our CPU usage has slowly been creeping up as
new programs have been added. As it stands right now, whenever I check CPU
usage I hardly ever see it below 80%. Usually it is in the 90%+ range. I
know it is frustrating to our users, and I can't blame them - I would hate
to wait for jobs to finish for long stretches at a time.
I would like to determine where the bottlenecks are occurring, and I wonder
if the group has any suggestions? Looking at the active jobs, I suspect it
may have something to do with all of the web pages that hit the 400 on a
regular basis - I see an awful lot of QZDASOINIT jobs occupying a fair chunk
of CPU usage. There are other jobs that run regularly that consume a fair
amount of usage as well.
Are there any free / built-in programs I can use to analyze the 400 to see
where and when these bottlenecks occur? I do have a HW/SW contract on the
400, so could I have IBM come in and perform an analysis on the system to
determine our problems? I'd hate to throw a bunch of money upgrading the
main storage/DASD/CPU to P20+ if that isn't really the problem (and I'm sure
our senior management group would be less than happy as well).
Any ideas would be most appreciated!
Thanks!
Brian.
