The MVS operator can dynamically change which SMF records and record
subtypes are being recorded by one of two methods:
- Issue a SET SMF = xx command
at an MVS console to activate a new SMF PARMLIB member. The xx identifies the SMFPRMxx member
of the SYS1.PARMLIB that is to be activated by SMF.
- Issue a SETSMF command at an MVS system console to add
a SUBPARM parameter or to replace any previously specified parameter
in the active SMF PARMLIB member except for the ACTIVE, PROMPT, SID,
or EXITS parameters.
