SMF Type 77 Record

This table shows the record layout for type 77 SMF records
(RMF Enqueue Activity - z/OS 1.13).

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

Purpose: Record type 77 is written at the end of each measurement interval and when the session is terminated. As with all SMF records RMF produces, it contains a header section followed by the RMF product section. These are followed by:

  • Enqueue Control Section Contains the status indicator.
  • Enqueue Data Section Identifies the resources for which ENQ/DEQ contention occurred during the measurement interval and describes any contention that occurred.

It's easy to report on SMF 77 data!

SMF Spectrum Writer
We have a low-cost 4GL report writer especially for SMF files. It's called Spectrum SMF Writer.

Spectrum SMF Writer handles the difficult SMF record parsing for you automatically. You just specify which fields you want to see.

Spectrum SMF Writer also converts the arcane date and time fields and reformats them into an attractive report.

Plus, Spectrum SMF Writer can export SMF data as comma delimited files to use on your PC.
