The SETSMF operator command allows an installation to add a SUBPARM parameter or to replace any previously-specified parameter in the active SMF parmlib member except the ACTIVE, PROMPT, SID, or EXITS parameters. The SETSMF command cannot be used with a parmlib member that specified NOPROMPT.
The SETSMF command cannot be used to change the SID parameter;
if a value is specified, it is ignored. If processor serial numbers
were displayed in message IEE967I prior to issuing the SETSMF
command, they will no longer be displayed following the SETSMF command.
Also, the SID parameter displayed in message IEE967I following the
SETSMF command will show an origin type of DEFAULT.
In this case, DEFAULT indicates that
the SID value is the value that was specified at IPL.
