Combined Format SMF Records

All CA ACF2 for z/VM SMF records are recorded using a single SMF number. This lets CA ACF2 for z/VM distinguish events through a one byte subtype code in each record. (This subtype is often called the CA ACF2 for z/VM SMF type.) Since VM does not support SMF records natively, z/OS SMF recording is similated for CA ACF2 for z/VM events. This simulated new record is referred to as the CA ACF2 for z/VM combined format SMF record.

The current CA ACF2 for z/VM format SMF record and SMF reports have the following features:

• The ACFSMF macro defines a common SMF header. This header defines the fields that are common to all or most CA ACF2 for z/VM subtypes.
• A variable section where the SMF subtype mapping macros define the fields unique to a CA ACF2 for z/VM subtype.
• Each CA ACF2 for z/VM subtype is fixed for all CA ACF2 for z/VM systems.
• Maintenance SMF records record ARE fields that update a LIDREC or structured infostorage record. This lets you display the fields that were changed in reports instead of using complete record images.
• A common SMF read program (ACF4BSMF) converts old format SMF records to combined format SMF records when it reads them for a report. Individual reports do not need to know of the conversion, nor do they need to know how to convert from one format to another. See the Systems Programmer Guide for additional information about converting SMF records to the combined SMF record format.
• Expanded selection parameters are provided for most reports, including SYSID selection (defined by the ACFFDR).
• You can use ACFRPTPP to preselect records. You can output preselected records to different files and then use them as input to supplied reports or user written reports. ACFRPTPP also uses ACF4BSMF to read SMF records, so user written reports can process old format SMF records without converting them.
