Hi Manshadi, You might check to see if you have Defined Capacity or Group Capacity setup on the HMC for the LPARs on this CEC. This would fit with the general symptom of IPL and then sometime later seeing a slowdown. You said 12 hours but I want to consider that might be subjective and not always exactly 12 hours. The RMF Monitor III screen CPC aka RMF V1R13 CPC Capacity shows if you have capped the LPARs.

Hi all, We have a parallel Sysplex with 2 members.one of them is a CPU Z900 (2064 -1C5) with Z/OS 1.8 as operating system and the other is CPU Z900(2064-216) with the same operating system. We have a weird problem with CPU 2064-216 as follows: When we power on reset the CPU and IPL from that,It works OK. for about 12 hours and after that it degrades and the jobs take much more times to complete.(about 4 times).The major things is decreasing No. of SIO for the jobs.after that even REIPL is not resolve the problem and we have to POWER ON RESET the CPU and REIPL for the next 12 hours!!. We exchange the operating systems between two CPUs but the problem is exactly the same. Does anybody have the same experience ? Any help should by highly appreciated.
