Use this page to enable SMF recording for WebSphere Application
Server and select SMF type 120 records for output to the SMF data
sets.
Procedure
- In the administrative console, click Servers > Application
Servers > server_name.
- On the configuration panel, click Server
Infrastructure > Java and Process Management > Process Definition
> Control > Environment Entries.
- To enable SMF type
120 records, click New, and specify one or more of the following
properties:
- name = server_SMF_server_activity_enabled = 1 (or server_SMF_server_activity_enabled
= true)
- name = server_SMF_server_interval_enabled = 1 (or true)
- name = server_SMF_container_activity_enabled = 1 (or true)
- name = server_SMF_container_interval_enabled = 1 (or true)
- name = server_SMF_interval_length, value=n, where n is the
interval, in seconds, that the system will use to write records for
a server instance. Set this value to 0 to use the default SMF recording
interval.
- Click OK or Apply.
- Save the changes and make sure a file sync is performed
before restarting the servers.
- For the changes to take effect, restart the application
server.
- 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))
- Use the SET command to indicate which SMF parmlib member
the system should use.
- Format the output data set.
