We have this degradation for all the jobs after 12 hours of POR and IPL. We are using Goal Mode. We are also change the volumes on other channels but the problem is same.
For test, we are using a simple DUMP JOB with following result : Before Problem: NP JOBNAME StepName ProcStep JobID Owner C Pos DP Real Paging SIO BKDUMP ADRDSSU JOB02189 IBMUSER A IN C0 1421 0.00 8572.2 -------------------------------------------------------------------------------------------------------------------------------------------- -STEPNAME PROCSTEP RC EXCP CONN TCB SRB CLOCK -ADRDSSU 00 302K 13318 .31 .00 .6 =============================================================================== After Problem : After 12 hours NP JOBNAME StepName ProcStep JobID Owner C Pos DP Real Paging SIO BKDUMP ADRDSSU JOB02100 IBMUSER A IN C0 1421 0.00 3200.2 -------------------------------------------------------------------------------------------------------------------------------------------- -STEPNAME PROCSTEP RC EXCP CONN TCB SRB CLOCK -DELET1 00 11 3 .00 .00 .0 -ADRDSSU 00 302K 13059 1.56 .01 1.6 1 Best regards Manshadi ________________________________ From: Elardus Engelbrecht <elardus.engelbre...@sita.co.za> To: IBM-MAIN@LISTSERV.UA.EDU Sent: Thursday, August 16, 2012 2:50 PM Subject: Re: Z900 (2064 - 216) Problem.

What jobs? How many jobs on what LPARs? Are they sharing workload and middleware? How long does the degrading take places? Try moving you data to another volsers to see if the problem is with some disks or channels (ESCON or FICON). What type of workload do you have? What middleware do you have? Can you post any SYSLOG message(s)? What is RMF, GRS, WLM and SMF showing you? >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!!. POR is too much taken in account of design of hardware and z/OS. Open a ticket with IBM rep.
