In contrast to the SET SMF command, which allows an installation
to specify a different SMFPRMxx parmlib member or to restart SMF,
the SETSMF operator command allows an installation to:
- Add a SUBPARM parameter value to those SMFPRMxx parameter values
already set for this IPL.
- Replace SMFPRMxx parameter values (except ACTIVE, PROMPT, SID,
and EXIT) with new ones for this IPL.
If the SMFPRMxx parameter values set for this IPL include NOPROMPT,
the operator cannot use the SETSMF command.
