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.
