SMF Type 42 Record

This table shows the record layout for type 42 SMF records
(DFSMS Statistics and Configuration).

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

Purpose: Record type 42 contains the following subtype information:

  • Subtype 1 — is created on a timed interval to collect device statistics. The time interval is specified in the IGDSMSxx parmlib member. Subtype 1 summarizes, on a storage-class basis, the buffer manager ‘hits’ (number of page-read requests handled by the buffer manager). A Buffer Manager Facility (BMF) totals section (64 bytes) enables analysis of overall BMF performance. There is one storage-class summary section (64 bytes) for each storage class.

  • Subtype 2 — has one section (88 bytes) for each cache control unit (Model 3990-3) having at least one Storage Management Subsystem- (SMS-) managed device attached. There is one section (16 bytes) for each SMS-managed volume attached to such a control unit.

  • Subtype 3 — is written each time the SMS configuration is changed. The following events cause subtype 3 to be generated:
    • The operator issued a VARY SMS command.
    • An ‘ACTIVATE’ occurred, either by issuing an ACTIVATE command in ISMF or a SETSMS command on the console.
    • An event notification facility (ENF) event occurred, because the operator issued a VARY command to an SMS-managed volume.
    • The status of a LIBRARY or DRIVE has been UPDATED by the Object Access Method (OAC).

  • Subtype 4 - is written to collect System Data Mover session statistics for a concurrent copy session or for an extended sequential data set when interfacing with the backup program. Concurrent copy records contain the identifier ‘CC’; extended sequential data set records contain ‘EXT’.
    • The CC SMF record is issued when the concurrent copy session completes.
    • The EXT SMF record is issued at the close of the processing for the extended sequential data set as follows:
      • If the backup program requested that the extended sequential data set be dumped to tape, one EXT SMF record is issued for reading the entire extended sequential data set.
      • If the backup program requested that the extended sequential data set be copied to DASD, one EXT SMF record is issued for reading the entire extended sequential data set and one EXT SMF record is issued for writing the entire extended sequential data set to DASD.
      • If the backup program requested that the extended sequential data set be processed using a concurrent copy session, then the CC SMF record contains the statistics for reading the extended sequential data set(s) and no EXT SMF record(s) is issued for reading the extended sequential data set(s). If the concurrent copy session was for a copy to DASD, one EXT SMF record is issued for writing each extended sequential data set to DASD.
    For additional information about SMF record 42 subtype 4, see Implementing Concurrent Copy.

  • Subtype 5 — includes storage class VTOC and VVDS I/O statistics. Subtype 5 is written when the global SMF interval expires. The global SMF interval is specified via the INTVAL parameter in the SMF parmlib member. Note: Record type 30 records may also be synchronized to the global interval. See “Performing interval accounting” on page 4-3 for more information on the use of record type 30.

  • Subtype 6 — records DASD data set level I/O statistics. There are two events that cause subtype 6 to be generated:
    • Close, or
    • Immediately after the recording of the type 30 interval record. There is one type 42 subtype 6 record for each type 30 interval record.

  • Subtype 7 — used by Network File System (NFS). See z/OS Network File System Customization and Operation for additional information.

  • Subtype 8 — used by Network File System (NFS). See z/OS Network File System Customization and Operation for additional information.

  • Subtype 9 — is written each time a B37/D37/E37 abend is issued. It includes information about the data set, UCB, JFCB and job that is abending.

  • Subtype 10 — is written at the time of volume selection failure because of insufficient space when allocating a data set.

  • Subtype 11 — is written for extended remote copy (XRC) session statistics whenever the SMF timer interval ends.

  • Subtype 14 — is written to report ADSTAR Distributed Storage Manager (ADSM) accounting for server resources used during a session.

  • Subtype 15 — can be created on a timed interval or whenever the SMF timer ends to collect data about VSAM record-level sharing (RLS) storage class response time. This data includes information for each system and a sysplex-wide summary.

  • Subtype 16 — can be created on a timed interval or whenever the SMF timer ends to collect data about VSAM RLS data set response time. This data includes information for each system and a sysplex-wide summary.

  • Subtype 17 — can be created on a timed interval or whenever the SMF timer ends to collect data about VSAM RLS coupling facility (CF) lock structure usage. This data includes information for each system and a sysplex-wide summary.

  • Subtype 18 — can be created on a timed interval or whenever the SMF timer ends to collect data about VSAM RLS CF cache partition usage. This data includes information for each system and a sysplex-wide summary.

  • Subtype 19 — can be created on a timed interval or whenever the SMF timer ends to collect data about VSAM RLS Local Buffer Manager LRU Statistics Summary. This data includes information for each system and a sysplex-wide summary.

For Subtypes 15, 16, 17, 18 and 19, specify the time interval in the IGDSMSxx parmlib member and activate recording on one system in the sysplex. Because data is collected across the sysplex, it is unnecessary to merge SMF records from all the systems in the sysplex.

  • Subtype 20 is written when STOW INITIALIZE is used to delete all the members from a PDSE to indicate who or what (job, started task, or TSO user) issued the STOW INITIALIZE. It contains the name of the data set and the volume serial of the volume on which it resided.

  • Subtype 21 is written when a member is deleted from a PDS or a PDSE to indicate who or what (job, started task, or TSO user) deleted the member. It contains the name of the data set and the volume serial of the volume on which it resided, as well as all the aliases of the member that will fit in the SMF record.

  • Subtype 22 is used by DFSMSrmm for audit records. Use the IBM assigned record type 42 subtypes 22 to avoid DFSMSrmm SMF records requiring record types from the user-written range.

  • Subtype 23 is used by DFSMSrmm for security records. Use the IBM assigned record type 42 subtypes 23 to avoid DFSMSrmm SMF records requiring record types from the user-written range.

  • Subtype 24 is written when a member is added or replaced from a PDS or a PDSE to indicate who or what (job, started task, or TSO user) added or replaced the member. It contains the name of the data set and the volume serial of the volume on which it resided. If the member replaced is a primary name in a PDSE, the SMF record will also include any alias names associated with the replaced member. The number of alias names included will be limited to the maximum size that can be contained in an SMF record.

  • Subtype 25 is written when a member is renamed from a PDS or a PDSE to indicate who or what (job, started task, or TSO user) renamed the member. It contains the name of the data set and the volume serial of the volume on which it resided, as well as the old name and new name of the member

Sample Report from SMF 42 Subtype 6 Records
showing DASD Stats by DSNAME


The sample SMF report below was created with Spectrum SMF Writer, the low-cost 4GL SMF report writer. It reads as input the SMF file and selects just the type 42 DFSMS statistics records. (See SMF 42 record layout.) It then prints a report line for each CLOSE of a dataset with a name matching the test criteria. The report shows job id and statistical information about the datasets, including average response time and total number of I/O's.

All of this with just a few lines of code!
