Hi Jim....we had similar issues when going to z/OS 1.9, looked like OA24615 at first, but ended up not being the case.
IBM found that we had a lot of sysout on the output queue with bits STST1CTK and STST1APC turned on, which meant that SDSF had to get verbose data from JES2 for each item, slowing things down. We ended up putting on the fix for PK52910, modifying the config of an ISV product to stop it creating sysout with STST1CTK on and having a really good clean up of the spool. Everything is pretty much ok now, except that we have found that there are a couple of internal applications that put out sysout with STST1CTK on (don't know why) which we need to keep an eye on...as still causes a bit of grief if there ends up being a lot of their output on the queue. Cheers...Jason.

It was tagged OA24615 and was opened up back in early 2008 or maybe earlier. I have been very vocal with IBM about the impact it is causing my Production Control staff especially on 2nd shift when they can not get out on time and go into overtime pay not mention the general impact on productivity of the ordinary programmers including my tech support staff. My recent inquiry says the fix will be out 12/26/2008 as PK69442 and would I like a fixtest of it. Has anyone already have the fixtest installed and does it indeed fix the performance problem. Seems like a rather a rather long time, 3+ months to be out as fixtest, before it is released, if indeed it fixes the problem. I would surmise either it fixes it or not. Anyone like to respond to save me from installing and finding out it did not fix things. jim National Australia Bank Ltd - ABN 12 004 044 937 This email may contain confidential information.
