No monitor sampling on the system, and no paging at all.
From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Mike Walter Sent: Tuesday, December 21, 2010 2:51 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Strange response time problems (also posted on VSE-L) David, Have you been able to detect if the "periods of time when VSEs do not respond at all" occur at the same intervals, or the same time of day each time? If so, would those time periods happen match your "MONITOR SAMPLE INTERVAL"? (To see, enter: CP Query MONitor) How's your paging load during those periods?

"Wakser, David" <david.wak...@infocrossing.com> Sent by: "The IBM z/VM Operating System" <IBMVM@LISTSERV.UARK.EDU> 12/21/2010 08:53 AM Please respond to "The IBM z/VM Operating System" <IBMVM@LISTSERV.UARK.EDU> To IBMVM@LISTSERV.UARK.EDU cc Subject Strange response time problems (also posted on VSE-L) All: We are running 2 2.3 VSE systems under z/VM 5.4 on a Z800 CPU. We are experiencing periods of time when VSEs do not respond at all (e.g. cannot get in via FAQS from CMS, etc.), even though nothing is running in the VSE system and the z/VM system is not very busy. At other times, we have excellent response times, though conditions on either the guests or the z/VM host didn't seem to change. We do not have any z/VM monitors (except Explore, which is not set up properly), and we have even tried QUICKDSP, without success. Is anyone aware of any PTFs that address this strange behavior? We believe it started when the system was upgraded to z/VM 5.4.
