How many CICS regions are you running? Maybe you should just try to split the application or applications up into several more regions. There are ways to do that with Vtam and IP so that the separation is transparent to end users.
We have a set of related applications that run in a single CICS region and they are always going sos and we keep having to lower max tasks so that it does not go sos. We have 3 regions all set up to go to run the stuff instead of in just 1 region but the people responsible for the applications insist on running in just 1, even though only a minor modification would have to be made to their code (some of the programs check applid). -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Jim McAlpine Sent: Wednesday, August 19, 2009 10:39 AM To: IBM-MAIN@bama.ua.edu Subject: Re: LPAR strictly for CICS Onlines On Tue, Aug 18, 2009 at 10:52 PM, gsg <gsg_...@yahoo.com> wrote: > We've been having a bunch of problems CICS short on storage , max task > etc... and I posed the question can we create a LPAR specifically for our > CICS > regions and another for our batch.

I know that CICS trace can burn a lot of cpu. If you can then look at setting the following - AUXTR=OFF, GTFTR=OFF, INTTR=OFF, SPCTR=OFF, STNTR=OFF, SYSTR=OFF, USERTR=OFF, Also look at your setting of the LE runtime option CBLPSHPOP and see if that can be set to OFF especially if your CICS programs do a lot of dynamic calls. These are old recommendations but worth revisiting when you are short of cpu power.
