Planning for z1.13 to 2.2 upgrade and found that we need to move to jes2 checkpoint mode Z11. 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
