Recording SMF Records for Catalog Events (SMFPRMxx)

You can use the system management facilities to record certain catalog events. These records can be used to keep track of catalog activity, and can be used during catalog recovery. These records are also valuable in diagnosing catalog problems, and should always be recorded.

With complete SMF information, you can determine which backup copy of a catalog is the most recent, and you can use the Integrated Catalog Facility Forward Recovery Utility to update a newly recovered catalog. You can also develop reporting applications to analyze or track catalog usage.

Table 1 lists the SMF record types used with the catalog. Define the SMFPRMxx member of SYS1.PARMLIB so that these record types are recorded. For complete information about defining this member, see z/OS MVS Initialization and Tuning Reference.

You can use the IFASMFI6 macro to map the fields of these records. For more information about using SMF data and the IFASMFI6 macro, and about the contents of these record types, see z/OS MVS System Management Facilities (SMF).
