SMF Type 99 Record (Subtype 14) - z/OS 1.13

This table shows the record layout for type 99 SMF records
(System Resource Manager (SRM) Decisions - z/OS 1.13).

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

Purpose: This record type is written by the SRM component. The records contain:

  • Performance data for each service class period
  • Trace codes representing the SRM actions
  • The data which SRM used to decide which actions to take
  • The controls SRM is using to manage work.

In addition, subtypes 1 and 9 will be written by the SRM component when running in compatibility mode.

Record 99 has the following subtypes:

Subtype 1 Contains system level data, the trace of SRM actions, and data about resource groups. The SRM actions are recorded in trace codes. All trace codes are described in z/OS MVS Programming: Workload Management Services. A subtype 1 record is written every policy interval.

Subtype 2 Contains data for service classes. A subtype 2 record is written every policy interval for each service class if any period in the service class had recent activity.

Subtype 3 Contains service class period plot data. A subtype 3 record is written every policy interval for each service class if any period in the service class had recent activity and plot data.

Subtype 4 Contains information about a device cluster. A device cluster is a set of service classes that compete to use the same non-paging DASD devices. A subtype 4 record is written every policy interval for each device cluster in the system.

Subtype 5 Contains data about monitored address spaces. A subtype 5 record is written each policy interval for each swapped in monitored address space.

Subtype 6 Contains summary information about each service class period, including the resource control settings for the next policy interval. A subtype 6 record is written each policy interval.

Subtype 7 Contains summary information for the Enterprise Storage Server (ESS) with Parallel Access Volume (PAV) feature. A subtype 7 record is written every third policy interval.

Subtype 8 Contains summary information for LPAR CPU management. A subtype 8 record is written each policy interval, when in LPAR mode.

Subtype 9 Contains summary information for dynamic channel path management. A subtype 9 record is written each policy interval.

Subtype 10 Contains information about dynamic processor speed changes. A subtype 10 record is written for every processor speed change.

Subtype 11 Contains information about Group Capacity Limits. A subtype 11 record is written every 5 minutes.

Subtype 12 Contains information about HiperDispatch. This information is for IBM internal use only.

Subtype 13 Contains information about HiperDispatch. This information is for IBM internal use only.

Subtype 14 Contains information about HiperDispatch. This information is for IBM internal use only.

It's easy to report on SMF 99 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.
