Issue/Introduction

Did you know that you could suppress specific SMF records and subtypes from being written to SYS1.MANxx data sets?

 

Environment

 SMF 

Resolution

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:

Syntax: type:subtype:action

    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.
