Hello, I am running zVM 4.2 in an LPAR on a zSeries machine with 4.5GB real storage and 1.5GB expanded storage defined to it. I have 12 to 15 zLinux guests active at any given time. The main Linuxes are DB2/UDB (3) and WebSphere (4). Each of these are defined with a virtual machine size of 512MB with 1G of swap using VDISK.
As you can see from the output of the "CP IND" command, there is signifcant page movement between expanded storage and central, but central is only 59% allocated. How can I determine what is causing this page movement? I there any way to "protect" a guest's working set short of running them V=R? Thanks in advance, Hank Calzaretta Moore Wallace ind AVGPROC-043% 01 XSTORE-000152/SEC MIGRATE-0026/SEC MDC READS-000019/SEC WRITES-000004/SEC HIT RATIO-044% STORAGE-059% PAGING-0036/SEC STEAL-039% Q0-00004(00000) DORMANT-00013 Q1-00000(00000) E1-00000(00000) Q2-00000(00000) EXPAN-001 E2-00000(00000) Q3-00013(00000) EXPAN-002 E3-00000(00000) PROC 0000-043% LIMITED-00000 Ready; T=0.01/0.01 09:21:11 q store STORAGE = 4608M Ready; T=0.01/0.01 09:21:36 q xstore XSTORE= 1536M online= 1536M XSTORE= 1536M userid= SYSTEM usage= 91% retained= 0M pending= 0M XSTORE MDC min=0M, max=0M, usage=0% XSTORE= 1536M userid= (none) max. attach= 1536M Ready; T=0.01/0.01 09:21:40 q srm IABIAS : INTENSITY=90%; DURATION=2 LDUBUF : Q1=300% Q2=200% Q3=100% STORBUF: Q1=200% Q2=175% Q3=150% DSPBUF : Q1=32767 Q2=32767 Q3=32767 DISPATCHING MINOR TIMESLICE = 5 MS MAXWSS : LIMIT=9999% ...... : PAGES=999999 XSTORE : 0% Ready; T=0.01/0.01 09:30:39
