When you set up SMF in a multisystem environment, you might need
to specify a recording data set for each system. If two or more systems
share an SMFPRMxx parmlib member, you can specify symbols in the recording
data set name in SMFPRMxx to allow the systems to specify unique values.
For example, suppose two systems share an SMFPRMxx parmlib member
that specifies the following:
DSNAME(&SID..MAN1,&SID..MAN2,&SID..MAN3)
Suppose the substitution text for the &SID symbol is SYSA on
one system and SYSB on the other. When you IPL system SYSA, the recording
data sets are:
- SYSA.MAN1
- SYSA.MAN2
- SYSA.MAN3
When you IPL system SYSB, the recording data sets are:
- SYSB.MAN1
- SYSB.MAN2
- SYSB.MAN3
If system A and system B are sharing the same catalog, you can
easily identify the systems to which the SMF data sets are associated.
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.
