Sharing an SMFPRMxx parmlib member in an SMF logging environment

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
