Use this page to edit the SMFPRMxx parmlib member and enable
SMF recording for WebSphere® Application Server
for z/OS®.
Before you begin
Make a working copy of the sample PARMLIB member SMFPRMYL.
About this task
Follow these steps to edit the SMFPRMxx parmlib member and
enable SMF recording for WebSphere Application Server:
Procedure
- Insert an ACTIVE statement to indicate
SMF recording. See z/OS MVS™ Initialization and Tuning Guide for more information.
- Insert a SYS statement to indicate
the types of SMF records you want the system to create. For example, use SYS(TYPE(120:120)) to select WebSphere Application Server type 120 records only. Keep the
number of selected record types small to minimize the performance
impact.
- You can specify the interval in which you want the Server
and Container interval records created (if no interval was specified
in administrative console for the server or container definition)
using the INTVAL (mm) statement in the SMFPRMxx
parmlib member . The default SMF recording interval is 30 minutes. See z/OS MVS Initialization and Tuning Reference for more information.
The server and container interval records
will use either:
- The value specified in the server/container definition as specified
in the administrative console
- The interval specified in the SMF parmlib member (from the SMF
product settings) if you specify a length of 0.
