SMF Type 90 Record

This table shows the record layout for type 90 SMF records
(System Status - z/OS 1.11).

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

Purpose: Record type 90 is written during initialization processing and whenever certain operator commands are issued. This variable length record is created for operator tracking and reporting of reliability data. It allows the installation to establish availability statistics.

The following events cause the recording of this record during IPL. (See the Product Section for the individual subtype indicator.)

  • SET TIME command
  • HALT EOD command
  • SET DATE command
  • SET OPT command
  • SETSMF command
  • SET SMF command
  • SET MPF command
  • SWITCH SMF command
  • SET DAE command
  • SET PFK command
  • SET PROG command
  • VARY WLM command
  • IPL
  • RESET command

Subtype 2 is written only if the CLOCK parameter is not specified on the SET DATE command. Any SET DATE command that uses the CLOCK parameter produces a subtype 1 record.

Subtype 8 is written only when the operator responds to message IEE956A, the system prompt for information about the IPL.

Subtype 23 is written each time the workload management service definition is installed on the WLM couple data set. A service definition is installed on the WLM couple data set by a function in the WLM ISPF application.

Subtype 24 is written each time a workload management service policy is activated. A service policy can be activated either by the VARY WLM command, or by a function in the WLM ISPF application.

Subtype 29 is written each time a LNKLST set is activated for the LNKLST concatenation, except during LNKLST set activation at IPL through the ACTIVATE statement in PROGxx - SMF is not active this early in IPL. Subtype 29 is written when the SET PROG and SETPROG LNKLST commands are issued after IPL to activate a new LNKLST set.

Subtype 30 is written each time a RESET operator command completes successfully. The record identifies the job that was reset, the operator who initiated the command, and the change that was requested.For an enclave, the record identifies the name of the owner address space, the user and application that initiated the request, and the change that was requested.

Subtype 31 is written each time a module has been added to or deleted from LPA after IPL through the SETPROG LPA command, the LPA statement of the PROGxx parmlib member via the SET PROG=xx command, or the CSVDYLPA macro.

Subtype 32 is written each time there is a successful policy change.

It's easy to report on SMF 90 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.

Subtype 24

Subtype 24 contains the workload management service policy, as mapped by the IWMSVPOL macro. It has a size dependency of 32K. If the policy exceeds 32K, additional subtype 24 records are written. Each subtype contains the header information. You must map the corresponding service policy information as mapped in IWMSVPOL. For a mapping of IWMSVPOL, see z/OS MVS Data Areas.

The field SMF9024N contains the number of subtype 24 records that are written to map the service policy. The field SMF9024P contains the length of the subtype 24.

Mapping a Single Subtype 24 Record: To map the WLM policy when there is one subtype 24 (SMF9024N = 1), base IWMSVPOL on ADDR(SMF90T24) + LENGTH(SMF9024P).

Mapping Multiple Subtype 24 Records: To map the WLM policy when there is more than one subtype 24 written (SMF9024N > 1), use the following procedure:
1. Determine the storage required by multiplying 32K times the number of subtype 24 records. 32K * SMF9024N
2. Obtain a storage block equal to 32K * SMF9024N
3. Read all (SMF9024N) subtype 24 records that have the same unique identifier (SMF9024I).
4. Copy the first subtype 24 record (SMF9024S=1) beginning at SMF9024A for a length of SMF90DLN - LENGTH(SMF9024P) to the start of the obtained storage.
5. Copy the next subtype 24 record (SMF9024S=2) beginning at SMF9024A for a length of SMF90DLN-LENGTH(SMF9024P) to the byte in the obtained storage immediately after the previous record.
6. Repeat the previous step for each additional subtype 24 record.
When you have merged all the subtype 24 records, map the resulting data to the IWMSVPOL mapping macro.

Subtype 32
Subtype 32 contains all the workload management scheduling environment information following a successful policy change. It has a maximum size dependency of 32K. If the information exceeds 32K, additional subtype 32 records are written. Each subtype contains the header information. You must map the corresponding scheduling environment information as mapped in IWMSVPSE. For a mapping of IWMSVPSE, see z/OS MVS Data Areas.

The field SMF9032N contains the number of subtype 32 records that are written to map the scheduling environment structure. The field SMF9032P contains the length of the subtype 32.

Mapping a Single Subtype 32 Record: To map the WLM scheduling environment structure when there is one subtype 32 (SMF9032N = 1), base IWMSVPSE on ADDR(SMF90T32) + LENGTH(SMF9032P).

Mapping Multiple Subtype 32 Records: To map the WLM scheduling environment structure when there is more than one subtype 32 written (SMF9032N > 1), use the following procedure:
1. Determine the storage required by multiplying 32K times the number of subtype 32 records. 32K * SMF9032N
2. Obtain a storage block equal to 32K * SMF9032N
3. Read all (SMF9032N) subtype 32 records that have the same unique identifier (SMF9032I).
4. Copy the first subtype 32 record (SMF9032S=1) beginning at SMF9032A for a length of SMF90DLN - LENGTH(SMF9032P) to the start of the obtained storage.
5. Copy the next subtype 32 record (SMF9032S=2) beginning at SMF9032A for a length of SMF90DLN-LENGTH(SMF9032P) to the byte in the obtained storage immediately after the previous record.
6. Repeat the previous step for each additional subtype 32 record. When you have merged all the subtype 32 records, map the resulting data to the IWMSVPSE mapping macro.

Scheduling Environment Information

(Offset from beginning of record: SMF90DOF)
00SMF9032S4binary
Sequence number. When the scheduling environment structure is larger than will fit in 1 subtype 32 record, this field describes the order in which individual records must be combined to view the entire scheduling environment structure.
44SMF9032N4binary
Number of subtype 32 records which must be combined to map the scheduling environment structure. When 1 record is enough, both SMF9032S and SMF9032N will be 1.
88SMF9032I4binary
Unique id that is used to ensure all “N” records of 1 policy can be combined without mixing data from 2 rapid VARY policy commands.
12CSMF9032AvariesEBCDIC
The active service policy. This area is mapped by IWMSVPSE.

The table above is based on the description provided by IBM in its "MVS Systems Management Facilities (SMF)" manual.
