Re: Loading TR9 on V7R1 - Performance Issues!

IIRC, during one of the performance mgmt sessions at the spring COMMON I
went to one of the IBM'ers mentioned that they do have customers who run
job watcher 24x7.

You might ask IBM if they have a recommended configuration for doing so.

Paul, I received CPF362E also. When I did the IPL though, it permanently
applied TR9, loaded all the other PTF Groups, automatically restarted the
system again and applied everything.

Everything worked just fine during the IPL. I just wish I knew what
happened before that IPL!

I've opened a PMR with IBM. They are taking a look at the performance data
that was collected during this event. This is what they had to say:

From the overview we can see there is an increase in the write times which
looks to have caused some seize and gate contention. Without a Job Watcher
collection we cannot see what the jobs were writing to or the
seizing/gating holder and waiter information. Typically when we see write
times increase like this we'd expect to see disk response also increase on
one or more drives, however, I'm not seeing that type of activity. I'm
still reviewing the data but would like PALs sent in.

I'm beginning to think that I should have Job Watched running all the time
just like I have performance collection running. This is the second time in
the last few months where IBM has wanted to look at Job Watcher data for an
event and I didn't have it and I wasn't able to recreate the event to get
it.

Is anyone else out there running Job Watcher along with performance
collection 7x24?
