Did you know that you could suppress specific SMF records and subtypes from being written to SYS1.MANxx data sets?
In parmlib member SMFDATA of the SCSYPARM dataset, you can suppress SMF records from being written to the SYS1.MANxx data sets. You can even be sub-type specific as the parameter is specified with a type, subtype and an action.
The parameter is SUPPRESS-SMF-RECORD-TYPE.
Here is the syntax of the parameter:
type - 000 to 255 or *
subtype - 000 to 255 or *
action - INCLUDE|EXCLUDE
INCLUDE - Suppress
EXCLUDE - Do not suppress
Here is an example of suppressing SMF 255 subtype 001 from the SYS1.MANxx data sets.
