SMF Type 18 Record

This table shows the record layout for type 18 SMF records
(Rename Non-VSAM Data Set Status).

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

Purpose: Record type 18 is written when a non-VSAM data set defined by a DD statement (either explicitly or implicitly) is renamed. (When a DD statement defines a volume, all the data sets on that volume are implicitly defined.) This record contains the old data set name, new data set name, number of volumes, and volume serial numbers. Its length varies, depending upon the number of volumes for the data set

It's easy to report on SMF 18 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 18 Record -- Rename Non-VSAM Data Set Status
Offset (Dec.)	Offset (Hex)	Name	Length	Format	Description
0	0	SMF18LEN	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	SMF18SEG	2	binary	Segment descriptor (see record length field).
4	4	SMF18FLG	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	SMF18RTY	1	binary	Record type 18 (X'12').
6	6	SMF18TME	4	binary	Time since midnight, in hundredths of a second, when the record was moved into the SMF buffer.
10	A	SMF18DTE	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	SMF18SID	4	EBCDIC	System identification (from the SID parameter).
18	12	SMF18JBN	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	SMF18RST	4	binary	Time since midnight, in hundredths of a second, that the reader recognized the JOB card (for this job).
30	1E	SMF18RSD	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	SMF18UID	8	EBCDIC	User-defined identification field (taken from common exit parameter area, not from USER=parameter on job statement).
42	2A	SMF18RIN	2	--	Reserved.
44	2C	SMF18ODS	44	EBCDIC	Old data set name.
88	58	SMF18NDS	44	EBCDIC	New data set name.
132	84	SMF18RV1	3	--	Reserved.
135	87	SMF18NVL	1	binary	Number of volumes.
Volume Information Section For each volume there is an eight-byte entry with the following format. (Offset from beginning of record: 136)
0	0	SMF18RV2	2	--	Reserved.
2	2	SMF18FVL	6	EBCDIC	Volume serial number.
