MAXCPUTIME is the time limit (in seconds) for processes that were created by rlogind, telnetd, and other daemons. You can set a system-wide limit in BPXPRMxx and then set higher limits for individual users. Use the RACF® ADDUSER or ALTUSER command to specify the CPUTIMEMAX limit on a per-process basis as follows:

ALTUSER userid OMVS(CPUTIMEMAX(nnnn))
