OAM uses system management facility (SMF) recording for gathering
OAM statistical information to allow customers to measure the performance
of OAM at the application programming interface level (the OSREQ macro
interface).
The OAM SMF record allows the collection of statistical information
about OAM usage for planning and diagnosis purposes such as:
- Information system usage accounting and charge back to user departments
- Performance analysis and monitoring to make certain that their
information systems are as finely tuned as possible
- Capacity planning to determine when to procure additional hardware
resources, such as storage devices (DASD, tape, optical) and media
- Potential problem determination data
The OAM SMF record subtypes are assigned to almost all OAM activities.
The MVS system operator or system programmer can dynamically select
the OAM SMF record subtypes to be recorded. The following activities
have associated subtype records:
- Invocations of OSR functions:
- ACCESS
- CHANGE
- DELETE
- QUERY
- RETRIEVE
- STORE
- STOREBEG
- STOREPRT
- STOREEND
- UNACCESS
