SMF Type 15 Record

This table shows the record layout for type 15 SMF records
(OUTPUT, UPDAT, INOUT, or OUTIN Data Set Activity).

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

Purpose: Record type 15 is written for non-VSAM direct access, or VIO tape data sets that are defined by DD statements or dynamic allocation and opened for OUTPUT, UPDAT, INOUT, or OUTIN processing by problem programs. It is written when a data set, as described above, is closed or processed by the end-of-volume (EOV). Its length varies, depending upon the number of volumes for the data set.

This record contains information from the TIOT, JFCB, DCB, DEB, and UCB data areas.

Note: Record type 15 is not written for data sets defined as SYSOUT data sets on DD statements. For accounting purposes, the SYSOUT logical record count is provided in record type 6.

The format for this record is the same as the format for record type 14.

It's easy to report on SMF 15 data! (Jump to sample reports)

UCB Section
This section contains a portion of the UCB (see fields SMF15NUC and SMF15SUC).
00SMF15UCBDV2binary
Device number. If this field contains X’7FFF’, this could be a virtual I/O (VIO) data set. If bit 7 of field SMF15RIN is set to one, this is a VIO data set. Note: Virtual I/O devices are identified by the following: Device Class 0 Unit Type 0 Device Number X'7FFF'It is important to understand the following: Allocation messages for VIO data sets will show VIO ALLOCATED TO ddname. SMF records will show VIO unit addresses as X'7FFF'. The actual in-storage UCB built for VIO will show address X'3FFF'. For example, the messages: - IEF237I X'3FFF' ALLOCATED TO ddname - IEF237I X'7FFF' ALLOCATED TO ddname indicate that ddname is not allocated to a Virtual I/O device, but is instead allocated to a real device whose unit address is X'3FFF' or X'7FFF' respectively.

For more information about EXCP count, see Chapter 10, “EXCP Count,” on page 10-1. For PDSE data sets, the number of pages that were read or written.

Example -- Sample Report from SMF 15 and 17 Records
showing 'Opens for Update' and 'Deletes' for Selected DSNAME


The sample SMF report below was created with
Spectrum SMF Writer, the low-cost 4GL SMF report writer. This is a simple example of producing a report from multiple SMF record types. It reads as input the SMF file and selects both the type 15 (DD opened for output or update) and type 17 (dataset deleted) SMF records. (See SMF 15 or SMF 17 record layout.)

This report selects only records with a specific text ("SPFTEMP") somewhere withing the DSNAME. (And note that the DSNAME field is not in the same location in type 15 and type 17 SMF records.)

It then prints a report line for each type 15 or 17 record that refers to "SPFTEMP" dataset. Each report line shows data from either the SMF 15 record or the SMF 17 record. The report is then sorted and grouped by job. (However, in this example only 1 job happened to pass the selection criteria.)

All of this with just a few lines of code!
