RE: Running jobs on a separate core



fixed

I don't know if a processor group will work in this case because ordinarily
the license program is set to run in a processor group. Having not tried to
push the QZDASOINIT and/or QSQSRVR jobs into one, I don't know if it can be
done (Domino and WAS can be pushed into one).

Look into processor groups, only because you have more than one processor.

Also in your performance investigations remember to look at index activity.
Unless this box is just stressed with workload, I usually find quite a bit
of temporary index activity in situations like the one you describe. You
should also see quite a bit of I/O activity on the disk units if indexing is
going on too.

Now there's an oxymoron: "new 400".

I don't believe there is a way to dedicate out processors like you can
memory. With memory, you can bust it up into subsystems and whatnot. This
has been around since, well, back on 400's.
About the only way to dedicate processors is to create separate partitions.

All,

In the next month or so our new 400 will be delivered to us. The new box
will have two cores because right now our single core machine is being
crushed by the QZDASOINIT jobs (they occupy anywhere from 75% - 90% of the
CPU utilization at any given time).

Yes, we are investigating the reasons why these jobs are occupying so
much, but I wanted to know if there's a way I can dedicate a core to a
specific job or subsystem? I would like to move the web jobs off to their
own core so the other core can focus on taking care of the other tasks.

Any advice or recommendations would be appreciated.


Thankee-sai!
