Wild-card characters are supported.
OUT file-spec
directs all SCF output to the specified file.
MON $ZSMS
is the SMF master process.
attribute-spec
is one or more “ALTER MON Attributes” (page 233).
ALTER MON Attributes
[ , BACKUPCPU number ]
[ , HIGHPIN { ON | OFF } ]
[ , MODE { NOISY | QUIET } ]
[ , PRIMARYCPU number ]
[ , PROGRAM [[$vol.]subvol.]fileid ]
BACKUPCPU number
is the processor in which the backup IOP starts. The process must be in the STOPPED state or
not running for you to alter this attribute.
HIGHPIN { ON | OFF }
specifies whether the IOP can run at a high PIN (ON, the default) or only at a low PIN (OFF).
MODE { NOISY | QUIET }
specifies whether to generate additional EMS messages for debugging
Generate additional EMS messages for debugging.NOISY
Generate only essential EMS messages (default).QUIET
PRIMARYCPU number
is the processor in which the primary IOP starts. The process must be in the STOPPED state or
not running for you to alter this attribute.
PROGRAM [[$vol.]subvol.]fileid
is the object file name of the IOP. If not specified, PROGRAM is:
$SYSTEM.SYSTEM.OMP
If you specify the program file name location as $SYSTEM.SYSTEM, the operating system first
searches for the file there and on the current SYSnn subvolume.
ALTER MON Examples
See the procedure for “Altering the Values of the SMF Master Process Attributes” (page 45).
• To change the mode to generate all the EMS messages:
-> ALTER MON $ZSMS, MODE NOISY
• To run the SMF master process in different processors:
-> ALTER MON $ZSMS, BACKUPCPU 0, PRIMARYCPU 1
