We experienced the exact same issue with the upgrade of our 1st LPAR from z/OS
v2.1 to v2.2 in early July. A ticket to IBM resulted in similar results: "The
PERFDATA display confirms the problem reported by OA50806 (RSM) and OA50777
(JES2) PTF availability for both APARs is 08/26/2016. ++APAR can be
provided on an emergency basis. However, there may be substantial work
involved when removing the ++APAR fixes before you can apply the official
PTFs.". So we are just awaiting IBM to notify me of the ptf's then we will
apply them. So, anyone who upgraded to v2.2 should check their before/after
CPU usage for JES2 and probably apply the ptf's. And yes, thanks to IBM for
quick resolution. (Note, a couple of years ago when we upgraded to v2.1, we
had a similar issue of increased CPU usage but that was resolved by a ptf for
the ThruPut Manager product.)
