A component trace provides data about events that occur within the component. You will typically use component trace while recreating a problem. The trace data is intended for the IBM® Support Center, which can use the trace to diagnose problems in the component.
TRACEOPTS ON
BUFSIZE(16M)
OPTIONS('CONNECT,LOGSTRM,DATASET,SERIAL,MISC,LOCBUFF,RECOVERY')
Rule: To reduce the likelihood of losing data in a wrapped buffer, it is recommended that the BUFSIZE not be lowered below 16 MB.
ROUTE *ALL,TRACE CT,ON,COMP=SYSLOGR,PARM=CTnLOGxx
ROUTE *ALL,D TRACE,COMP=SYSLOGR
The SYSLOGR status should be ON, and the OPTIONS should match the options you specified in the CTnLOGxx parmlib member.
See the component trace chapter of z/OS MVS Diagnosis: Tools and Service Aids for information about requesting and formatting the component trace.
