Well, we were already at Z11 mode, and post 2.2 you can go to Z22 mode to get the new JES features. One of the pre-req's to get there is CYL_MANAGED=ALLOWED. We had that turned off. Turned it on dynamically in my TECH environment and instantly all of my Roscoe users were unable to view any JES output created after turning it on, and worse yet, turning it back off, the output was still unable to be accessed from Roscoe. CA is still working on fixes. And, as an FYI, CYL_MANAGED=ALLOWED came along in z/OS 1.11. As an aside, our spool is all mod-54's, and could be part of the reason why CA has had a hard time replicating the problem on their end.

We are a monplex so no MAS to be concerned about. I gather from reading the jes2 init and tuning, Reference guide and JES2 Performance and Availability Considerations in Redbooks the following. Use $DACTIVATE command and resolve outstanding requirements, for me that looks like moving to LARGEDS support. Change SPOOLDEF, LARGEDS=ALLOWED ($T SPOOLDEF,LARGEDS=ALLOWED) Issue $ACTIVE Did I miss any steps? thanks Matt This would be done during a scheduled system outage so there would be no activity. What I can't find is how to test afterward, what problems to look for, how to back out if necessary? Below is the display of the jes dactivate. $HASP895 $DACTIVATE 997 $HASP895 JES2 CHECKPOINT MODE IS CURRENTLY Z2 $HASP895 THE CURRENT CHECKPOINT: $HASP895 -- CONTAINS 32100 BERTS AND BERT UTILIZATION IS 1 $HASP895 PERCENT. $HASP895 -- CONTAINS 1847 4K RECORDS. $HASP895 z11 CHECKPOINT MODE ACTIVATION WILL: $HASP895 -- EXPAND CHECKPOINT SIZE TO 2149 4K RECORDS. $HASP895 -- REQUIRE 0 ADDITIONAL BERTS AND UTILIZATION $HASP895 WOULD REACH 1 PERCENT. $HASP895 z11 ACTIVATION WILL FAIL IF ISSUED FROM THIS MEMBER. $HASP895 THE FOLLOWING ISSUES PREVENT ACTIVATION: $HASP895 -- LARGEDS SUPPORT MUST BE ACTIVATED. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN This e-mail transmission contains information that is confidential and may be privileged.
