->For years, JES2 wouldn't release spool space allocated to a given job ->until all of the job was purged - i.e. freeing SPOOL space seemed to be ->an all-or-nothing proposition. I learned today that JES2 frees up ->SPOOL space for spin-OFF SYSOUT data sets (FREE=CLOSE) as soon as ->they're printed or purged, i.e. JES2 no longer waits for the entire job ->to get purged in order to free up some of the space allocated to it. ->Apparently, this isn't something new at all: a quick test on my RESCUE ->system shows that JES2 already behaved like that on MVS/ESA 5.2.2. ->When did JES2 start freeing SPOOL space for spin-off data sets? Am I ->confused again? Thanks.
Gilbert, I am not entirely sure on this, but functionality for all JES2 SYSOUTs seems to have changed with our latest upgrade to z/OS 1.6 (at least this is when I started noticing). It appears that the SYSOUT (even without FREE=CLOSE) remain independent of each other within the Outgroup number groupings and allow rerouting of segments within an OUTGRP to separate destinations, classes, etc. For instance, if you run a simple IEBGENER and have your SYSUT2 route to the same OUTGRP as your MSGCLASS going to the held queue, you can enter the held queue of SDSF, type a '?' next to the output, and change it whichever class or destination you like. When you perform this, the OUTGRP number gets reassigned for the entry to the next sequential number. I believe this new (new to me anyway) ability to separate the SYSOUT and keep them independent is what allows JES2 to now free up space. If you purge this output from the queue, you should notice the space is cleared. As I recall, the SYSOUTs coded with FREE=CLOSE were always assigned their own exclusive OUTGRP number and thus space was freed when they were purged or printed. I could be wrong there though. When I started noticing this behavior recently, I thought I was going crazy and wondered if it was always like this. Hope this helps...
