SMF Type 71 Record

This table shows the record layout for type 71 SMF records
(RMF Paging Activity - z/OS 1.10).

List of other SMF record layouts available.
List of sample SMF reports.

Purpose: Record type 71 is written for each measurement interval and when the session is terminated. Record type 71 contains information about the demands made on the system paging facilities and the utilization of central storage, expanded storage, and external page storage during the reporting interval. As with all the SMF records RMF produces, it contains a header section followed by the RMF product section. These are followed by:

  • Paging Data Section Includes information on central storage pages and expanded storage pages for SQA, SPA, CSA, LSQA and REGIONS+SWA.
  • Swap Placement Sections There is one swap placement section for each swap reason. If there were no swaps for a particular reason, its data fields contain zeroes. The sections are ordered as follows:
    1. Terminal output wait
    2. Terminal input wait
    3. Long wait
    4. Auxiliary storage shortage
    5. Central pageable storage shortage
    6. Detected wait
    7. Request swap
    8. Enqueue exchange
    9. Exchange on recommendation value
    10. Unilateral
    11. Transition to non-swappable
    12. Improve central storage usage
    13. Improve system paging rate
    14. Make room to swap in a user who has been swapped out too long
    15. APPC WAIT
    16. OMVS input wait
    17. OMVS output wait.
    18. In-Real swap.

It's easy to report on SMF 71 data!
