Issue CP IND USER linuxXyz Then we can see how big your Linux guest is. The Q V STOR is followed by a Ready message, which tells us it is executed under CMS, hence probably not in the Linux guest, but e.g. in MAINT, and your command would reveal how big MAINT is defined. 2008/3/21, O'Brien,

Thank you to all who have responded. What follows is the latest feedback from the person tasked with fixing this problem: Today we were able to re-allocate 512m of central storage to the Linux guests. This will place us comfortably below the 2gig available for VM. We performed this by a

The guideline for LDUBUF is to LOWER it from default, NEVER raise it unless you like to re-IPL z/VM. O'Brien, David W. (NIH/CIT) [C] wrote: I made the mistake of believing what I was told. cp q storage 05:57:21 STORAGE = 2G Ready; T=0.01/0.01 05:57:21 cp q virtual storage 05:57:35

There may be extra migration steps, refer to RACF's program directory to find out. There were for each major RACF release change, and I would be surprised if there were now: pass phrase support may require extra fields in the RACF database. 2008/3/21, Thomas Kern [EMAIL PROTECTED]: Very
