SMF Type 25 Record

This table shows the record layout for type 25 SMF records
(JES3 Device Allocation).

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

Purpose: Record type 25 is written for each job that completed JES3 converter/interpreter (C/I) processing. One type 25 record is written for each job, whether the job contains DD statements. A separate type 25 record is written for each job that uses a private catalog. A separate type 25 record is written for each main device scheduling (MDS) dynamic unallocation request.

It's easy to report on SMF 25 data!

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.

SMF Type 25 Record -- JES3 Device Allocation
Offset (Dec.)	Offset (Hex)	Name	Length	Format	Description
0	0	SMF25LEN	2	binary	Record length. This field and the next field (total of four bytes) form the RDW (record descriptor word). See “Standard SMF Record Header” on page 13-1 for a detailed description.
2	2	SMF25SEG	2	binary	Segment descriptor (see record length field).
4	4	SMF25FLG	1	binary	System indicator: Bit Meaning When Set 0-2 Reserved 3-6 Version indicators* 7 Reserved.*See “Standard SMF Record Header” on page 13-1 for a detailed description.
5	5	SMF25RTY	1	binary	Record type 25 (X'19').
6	6	SMF25TME	4	binary	Time since midnight, in hundredths of a second, that the record was moved into the SMF buffer.
10	A	SMF25DTE	4	packed	Date when the record was moved into the SMF buffer, in the form 0cyydddF. See “Standard SMF Record Header” on page 13-1 for a detailed description.
14	E	SMF25SID	4	EBCDIC	System identification (from the SID parameter).
18	12	SMF25JBN	8	EBCDIC	Job name. The job name, time, and date that the reader recognized the JOB card (for this job) constitute the job log identification, or transaction name (for APPC output).
26	1A	SMF25RST	4	binary	Time since midnight, in hundredths of a second, that the reader recognized the JOB card (for this job).
30	1E	SMF25RSD	4	packed	Date when the reader recognized the JOB card for this job, in the form 0cyydddF. See “Standard SMF Record Header” on page 13-1 for a detailed description.
34	22	SMF25UIF	8	EBCDIC	User-defined identification field (taken from common exit parameter area, not from USER=parameter on job statement)
42	2A	SMF25IND	2	binary	Allocation indicators Bit Meaning When Set 0 If zero, allocation by user’s DD statements. If 1, dynamic allocation. 1 If zero, non-catalog allocation by JES3. If 1, catalog allocation by JES3. 2 If zero, manual allocation by operator. If 1, automatic allocation by JES3 (see the ALLOCATE= keyword on the JES3 SETPARAM initialization statement in z/OS JES3 Initialization and Tuning Reference). 3-15 Reserved.
44	2C	SMF25NTF	4	binary	Number of IAT5110 GET messages for tape volumes issued for the job.
48	30	SMF25NDF	4	binary	Number of IAT5110 GET messages for disk volumes issued for the job.
52	34	SMF25FST	4	binary	Time since midnight, in hundredths of a second, that the fetch processing ended. That is, the time that the first phase of MDS ended. (During this phase, messages are issued to inform the operator of the volumes required for the job to run.)
56	38	SMF25FSD	4	packed	Date when the fetch processing ended, in the form 0cyydddF. See “Standard SMF Record Header” on page 13-1 for a detailed description.
60	3C	SMF25SST	4	binary	If manual allocation, the time when the *START SETUP operator command was issued. If automatic allocation, this field contains zeroes.
64	40	SMF25SSD	4	packed	If manual allocation, the date when the *START SETUP operator command was issued. If automatic allocation, this field contains zeroes.
68	44	SMF25NTM	4	binary	Number of tape volumes mounted by MDS.
72	48	SMF25NDM	4	binary	Number of disk volumes mounted by MDS.
76	4C	SMF25MST	4	binary	Time since midnight, in hundredths of a second, when all JES3 volume mount messages have been issued. If not mounts were required, this field equals the time of JES3 allocation.
80	50	SMF25MSD	4	packed	Date when all JES3 volume mount messages have been issued, in the form 0cyydddF. See “Standard SMF Record Header” on page 13-1 for a detailed description. If no mounts were required, this field equals the date of JES3 allocation.
84	54	SMF25VVT	4	binary	Time since midnight, in hundredths of a second, of JES3 device verification.
88	58	SMF25VVD	4	packed	Date of JES3 device verification, in the form 0cyydddF. See “Standard SMF Record Header” on page 13-1 for a detailed description.
92	5C	SMF25NMV	4	binary	Number of Mass Storage Volume requests allocated by MDS for the job. Note: As of MVS/SP4.1, this field is no longer valid.

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