Erik, The "z/OS V1R10.0 TSO/E Customization" reads in chapter 3.2.2 about limiting TSO user's region size: 1) Logon pre-prompt exit 2) SIZE operand of LOGON command 3) default region size defined to user (RACF TSO segment as I assume) and two other. Point 3) seems to be relevant here. The "z/OS Security Server RACF Command Language Reference" reads about the TSO segment: "The specified value must be an integer 0?65535 if the database is shared with any MVS systems, or 0?2096128 if the database is not shared with any MVS systems." So if you have a RACF database not shared with any MVS system, I think this should be your explanation on this number.
Cheers Michael Erik Janssen <erik.jans...@ing.nl> Gesendet von: IBM Mainframe Discussion List <IBM-MAIN@bama.ua.edu> 29.06.2010 16:07 Bitte antworten an IBM Mainframe Discussion List <IBM-MAIN@bama.ua.edu> An IBM-MAIN@bama.ua.edu Kopie Thema TSO region size Hello List, We are standardising our default TSO region sizes on 64MB since we start seeing more and more problems with programs abending, because people still have 4MB region size as a default. 64MB seemed like a reasonable value to solve some of the issues and not introduce any new. Testing the changes I noticed when I log on to TSO the help panel says that the maximum possible region size is 2096128. This is 1 MB less than 2 GB, which would be 2097152. Can somebody tell me why the max is not exactly 2GB?
