Thanks Sam,
I was just visiting this a few months back. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Knutson, Sam Sent: Wednesday, June 14, 2006 12:33 PM To: [email protected] Subject: SMSPDSE virtual storage exhaustion IPL APAR OA15185 Hi, It is SHARE my pain time again:-( My most recent adventure was a result of a storage creep in the SMSPDSE address space which resulted in 0F4 abends for jobs using PDSE data sets which impacted almost everything here. This defect is described by OA15185 and fixing PTFs are available. I would suggest that you add SMSPDSE to routine checking for virtual storage utilization. I added it to the list of jobs I get RMF virtual storage detail for and review weekly. We picked this problem up with z/OS R6 and were able to stay up about 7 weeks before everything went pear shaped as a result of this problem. You can check this on-line with TMONMVS PRIVATE AREA SUBPOOL DISPLAY/PRIVATE AREA MAP DISPLAY other MVS monitors should have similar displays. If you check this on a recurring basis you can avoid an unplanned outage even if you are having the problem as the storage leak takes place slowly over time. There is no way to resolve this without an IPL. We are also working on implementation of the Partitioned Data Set Extended Restartable Address Space (SMSPDSE1) which is a feature that was available at z/OS R6. http://www.redbooks.ibm.com/abstracts/tips0531.html IBM Level-2 PDSE provided a list of service they strongly recommended if we were going to start using SMSPDSE1.

The list of service they suggested for us to install as part of a plan to begin using SMSPDSE1 includes some fixes not listed in the informational APARs yet. I am working with IBM support to see why these SVC dumps for 0F4 not being processed by DAE which resulted in 1400+ SVC dumps being captured and the lack virtual storage health monitoring inside SMSPDSE(1) by any of the PDSE MONITOR functionality.
