If you use my REXXSTOR exec (see URL below) you can tell if it is IEFUSI or not. IEFUSI limits will show up under Max Priv Reg Size. The MAXASSIZE will show up under Region Limit / Region Size. On my system the actual region limit shown is about 10M below MAXASSIZE. I'm not sure what eats up that 10M or 75M on your system, but why not just set it at 2147483647 and be done with it.

Re: MAXASSIZE restriction
I remember that there is a AMAXSIZE parm set for the RACF userid (or something similar) that can override MAXASSIZE. -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Brian Szott Sent: Thursday, July 23, 2009 1:47 PM To: IBM-MAIN@bama.ua.edu Subject: MAXASSIZE restriction We reset the MAXASSIZE to 900M.

Antwort: Re: MAXASSIZE restriction
Hi, the field in the RACF OMVS segment is ASSIZEMAX. It has to be seen together with the BPXPRMxx symbol MAXASSIZE. Check the Unix System Services Planning Guide, chapter 3.6.3.3 for details. These max-values are among others which I call hard limits. In addition, Unix processes may obtain corresponding soft limits, for example from the /bin/ulimit command or the BPX1SRL callable service. The soft limits can be used to change certain limits to higher or lower values than the hard limits, again check the Unix Planning Guide, chapter 18.15. So, setting BPXPRMxx and RACF OMVS segment is only one part of the story. In addition, one should have a look for example into the profile file concatenation in HFS for calls to the /bin/ulimit program.
