Allen, Oops wanted to include this into the original post. Appears to me there should be plenty of free records here? The increase I believe is 302? Thanks Matt

I presume this will occur on the z/OS 1.13 system prior to the upgrade. $TSPOOLDEF should present no issues. At z/OS 1.13 you can issue $DACTIVATE, LEVEL=Z2 to "backout the upgrade. This *IS NOT* available on z/OS 2.2. Z11 mode has been out for such a long time that I cannot forsee any issues at this point in time. You *MIGHT* consider enlarging the checkpoint dataset based on "$HASP895 -- EXPAND CHECKPOINT SIZE TO 2149 4K RECORDS.". I can't be certain without seeing the O/P of $DCHKPTSPACE. HTH, <snip> 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?
