For example, here is what the REXXSTOR output looks like from one of the systems I am on: V I R T U A L S T O R A G E U S A G E ------------------------------------------- Region requested: 55296K Max Priv Region Region Region LSQA Region Reg Size Limit Size In-Use In-Use Avail -------- -------- -------- -------- -------- -------- Below 16M: 10216K 9728K 9728K 4K 280K 9724K Above 16M: 1686528K 262144K 262144K 700K 10776K 261444K Above 2G : 10G (64-bit MEMLIMIT) MEMLIMIT Source: SMF Before someone asks about the region requested size of 55296K (54M), this explains it: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/BPXZB2A1/20.8 or http://tinyurl.com/3hel6vh "When the IEFUSI exit receives control, one of the parameters that is passed is the region size that was requested for the JOB or EXEC test JCL statement. For a forked address space, this is displayed as 54M. This value comes from the default SWA blocks that are defined in module BPXPRBS. This is the default JCL that is used when creating forked address spaces.
