Hi
I don't remember to see anything like this, but as we changed
accidentally some LE runtime options, it had
a very bad impact on the CPU usage of the XPLINK applications. Here
maybe the "D CEE,ALL" would help.
First I would try to find out who are the main contributors for this
100% load. If nothing better, the RMF III workflow exception report can
point out the critical applications

Sorry, kind of misleading in original post because the CPU only stays at 100%
during the day, mostly 9am(ish) - 3pm(ish) with an obvious drop-off noon-1pm.
I definitely worked on IEFACTRT but it was because of rate changes (we bill for
CPU usage) so I know it's been reassembled!
You've made me paranoid that I've already asked this question and if I did,
blame it on sometimer's disease..lol

Subject: Re: increased CPU usage z/os v1r13
Migrated back in October, z/OS 1.11 to 1.13. Saw nothing of the like.
For some reason I kinda remember another email on this subject sometime in the
last 6 months or so. Please don't hold me this to this but an exit may have
needed reassembled and I wanna say it was iefactrt that was not working right.
You might be able to search the archives for it.
Sorry best this feeble brain can do.

z/os v1r11)
I've looked for information on increased CPU for 1.13 but haven't found much.
I see now that there is a product you can download to predict increased CPU
when migrating, but, unfortunately, I didn't realize that until now. I can't
say for sure what kind of percentage the CPU was peaking at for 1.11, but I
know that we did not get these phone calls complaining about response time!
I just wondered if anyone else experienced a significant increase in CPU usage
going to 1.13?
