When you set up SMF logging in a multisystem environment, you specify
a log stream for each system. If two or more systems share an SMFPRMxx
parmlib member, you can specify symbols in the log stream name (LSNAME
parameter) in SMFPRMxx to allow the systems to specify unique values
based on the system IDs. For example, suppose two systems share an
SMFPRMxx parmlib member that specifies the following:
LSNAME(IFASMF&SID..PERF,IFASMF.&SID..JOB,)
Suppose the substitution text for the &SID symbol is SYSA on
one system and SYSB on the other. When you IPL system SYSA, the log
stream names are:
- IFASMF.SYSA.PERF
- IFASMF.SYSA.JOB
When you IPL system SYSB, the log stream names are:
- IFASMF.SYSB.PERF
- IFASMF.SYSB.JOB
For more information about symbols and how to specify them in SMFPRMxx,
see the topic on sharing parmlib members and the description of SMFPRMxx
in z/OS MVS Initialization and Tuning Reference.
