Enabling SMF recording

Why and when to perform this task

Perform the following steps to enable SMF recording for WebSphere Application Server and select SMF type 120 records for output to the SMF data sets. For an overview of SMF recording, see Chapter 1 of z/OS MVS System Management Facilities (SA22-7630).

Steps for this task

  1. Use the WebSphere Application Server administrative console to enable properties for specific record types (see Using the WebSphere Application Server administrative console to enable properties for specific SMF record types for details).
  2. Edit the SMFPRMxx parmlib member and update the SYS or SUBSYS(STC,...) statement to include the type 120 record.
    SUBSYS(STC,EXITS(IEFU29,IEFACTRT),INTERVAL(SMF,SYNC), TYPE(0,30,70:79,88,89,120,245))
  3. Use the SET command to indicate which SMF parmlib member the system should use.
    You must issue the SET command before you start WebSphere Application Server. If you issue the command after the application server has started, SMF type 120 records will not be collected.
  4. Format the output data set.

Results

You have successfully enabled SMF recording when the SMF data is recorded in the data set which is specified in SMFPRMxx.
