Used to be about 256M, but at CFLEVEL 17 you need about 512M. That wasn't documented or talked about during our z196 migration planning with IBM and I ran into a problem in my sandbox sysplexes which only had 256M on the CF LPARs. It has been documented now in various places. Here is a post of mine from January 2012 that explained why the extra storage was needed. https://listserv.ua.edu/cgi-bin/wa?A2=ind1201&L=ibm-main&D=1&T=0&O=D&F=&S=&X=086E2A74E9A368C125&Y=mark%40mzelden.com&P=246772 Mark -- Mark Zelden - Zelden Consulting Services - z/OS, OS/390 and MVS mailto:[email protected] ITIL v3 Foundation Certified Mark's MVS Utilities: http://www.mzelden.com/mvsutil.html Systems Programming expert at http://search390.techtarget.com/ateExperts/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
