MAXASSIZE
MAXASSIZE is the maximum region size (in bytes) for an address
space that was created by rlogind, telnetd, and other daemons. You
can set a system-wide limit in BPXPRMxx and then set higher limits
for individual processes. Use the RACF® ADDUSER
or ALTUSER command to specify the ASSIZEMAX limit on a per-process
basis as follows:
ALTUSER userid OMVS(ASSIZEMAX(nnnn)
