Active jobs: 1222, even with 10 batch jobs running at one, 2nd core never used.
Spikes are hitting .8, never goes over 1.0

You ought to try running more than one job at a time. The fact that one or more is single threaded doesn't matter. One could be running on one core and the second on the other.

I have 2 cores on my production LPAR, 2nd core is never used, majority of
AS/400 software is single threaded, biggest reason why the core is not
used.
Confirmed this with MPG performance processor used graph.

Jim hit the biggest one
Was the LPAR profile changed to use the extra processor?
I can go to my HMC and activate another core by entering the key in our
Capacity Upgrade on Demand. However, if I don't then allocate that to one
or more lpars it's a waste of money.
Jim, I too initially thought he didn't want to apply the TR. I reread it.
He does want to apply the TR. He was just under the impression that it
wasn't included on the cume. It is, IBM's just behind on their
documentation. I've submitted web feed back that they get the cover
letter for TR6 updated to show the PTF's are now on a cume.

Kurt,
I agree with your partners request, I would make the same one. That
said, if you have seen no improvement, I suspect a different problem
than PTFs. Is this an LPAR box? Was the LPAR profile changed to use
the extra processor? Is there a high limit on the processor that is
less than (I think two based on your description) the number of
processors you had before adding one?
Yes, you can apply the cumulative and then go back and apply the group
for the TR later; But I highly suggest that in addition to the
Cumulative you apply the following list of groups as well:
PTF Group Text
SF99710 CUMULATIVE PTF PACKAGE C3037710
SF99709 GROUP HIPER
SF99708 GROUP SECURITY
SF99705 HARDWARE AND RELATED PTFS
SF99701 DB2 FOR IBM I
SF99627 7.1 ELECTRONIC SERVICES GROUP PTF
SF99572 JAVA
SF99368 IBM HTTP SERVER FOR I
SF99367 TCP/IP PTF
SF99366 PRINT PTFS
SF99362 BACKUP RECOVERY SOLUTIONS (even if you don't use
BRMS this is where all the save/restore PTFs are)
SF99145 PERFORMANCE TOOLS (if you have them)
The TR is SF99707 TECHNOLOGY REFRESH
The HIPER, and Hardware ones are the ones I would find most important in
this case, however if your taking the time to apply any Group you might
just as well get the entire batch. I'm not sure why you would not
want the TR group as well, unless there is something in the cover letter
that leads you to believe there is going to be a problem.

So we've been really bad about PTFs. Our IBM BP is asking that we apply
PTFs because after getting an additional core activated (from 1 to 2)
we've noticed 0 improvement on the system.
So we finally ordered a cumulative PTF and we're looking at applying it.
But then I thought, "What about technology refreshes?" It doesn't
appear that the cume comes with a TR on it. Cume: C3037710
http://www-912.ibm.com/systems/electronic/support/s_dir/sline003.nsf/PSP%20Number%20View/SF98035
Are we safe to apply the Cume w/o a TR and then later investigate
applying a Technology Refresh?
