Paul,

Thanks for the update.
We are running 2.1 and did not have the problem, so we will probably not see it 
in 2.2 either.

Regards,
Kees.

Subject: Re: Question about memory usage under z/OS 2.2

Kees, APAR PI72631 may interest you.  This APAR was opened up because of our 
issue we ran into under z/OS 2.2.  We are being told this also affects z/OS 
2.1.  This APAR really does nothing for the overall memory usage.  As for the 
memory usage, IBM made a change in z/OS 2.2 around how they handle CSM storage 
which caused an increase in size.  We have setup some automation to issue the " 
MODIFY vtamname,CSM,FIXED=xxxM" command if we get constrained on CSM storage.


  APAR Identifier ...... PI72631      Last Changed ........ 16/11/23

Paul,

We are going to 2.2 soon. Do you have information about the problems? APAR 
numbers, PTFs?

Thanks,

Kees.

Mike, thanks for the information.  I will review the documents.  An update on 
one of our issues. It looks like IBM has found some type of bug related to CSM 
storage management.  I'm being told an APAR is going to be created.


Thanks..

If you were running close to the limit prior to upgrade to z/OS V2.2 without 
realising it you may just need to review some settings.

CSM with D NET,CSM and SYS1.PARMLIB(IVTPRM00) are a good place to start. 

You may need to look at this if you've added IP interfaces or turned on 
multiple OSA queues.

InbPerf: Dynamic

  WorkloadQueueing: Yes

Also D NET,BFRUSE
