SMF Type 63 Record

This table shows the record layout for type 63 SMF records
(VSAM Catalog Entry Defined).

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

Purpose: Note that since VSAM catalogs are no longer supported (and no longer exist) record type 63 is no longer created.

Record type 63 is written when an entry (a component, cluster, catalog, alternate index, path, or non-VSAM data set) in a VSAM catalog is defined by the DEFINE access method services command and when that definition is altered. For example, when an entry in a VSAM catalog is altered with new space allocation information (that is, when the VSAM End-Of-Volume (EOV) routine extends the entire object) or, if the entry is changed by the Alter Access Method Services command. One record type 63 is written for each newly created or altered entry. This record is not written when a VSAM catalog is renamed. In that case record type 68 is written.

The record’s length includes the length of the catalog records required to describe the entry. The total length can be from 1000 to 4000 bytes or more, depending upon the sizes of the new and old catalog records (offsets 44 and 46 respectively). If you write this record to the SMF data set, you must include the sizes of these catalog records when estimating the additional storage required for the SMF buffer and the SMF data sets.

Record type 63 identifies the catalog in which the object is defined, gives the catalog record for the newly defined object, and, for an alteration, gives the parts of the old catalog record before they were altered. It identifies the job by job log identification and user identification. The job name and the time and date that the reader recognized the JOB card for this job constitute the job log identification. If a system task caused the record to be written, the job-name and the user-identification fields contain blanks and the time and date fields contain zeros.

It's easy to report on SMF 63 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 63 Record -- VSAM Catalog Entry Defined
Offset (Dec.)	Offset (Hex)	Name	Length	Format	Description
0	0	SMF63LEN	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	SMF63SEG	2	binary	Segment descriptor (see record length field).
4	4	SMF63FLG	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	SMF63RTY	1	binary	Record type 63 (X'3F').
6	6	SMF63TME	4	binary	Time since midnight, in hundredths of a second, that the record was moved into the SMF buffer.
10	A	SMF63DTE	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	SMF63SID	2	EBCDIC	System identification (from the SID parameter).
16	10	SMF63SMI	2	EBCDIC	System model identifier.
18	12	SMF63JBN	8	EBCDIC	Job name. If a system task caused the record to be written, the job name and user identification fields contain blanks and the time and date fields contain zeros. 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	SMF63RST	4	binary	Time since midnight, in hundredths of a second, that the reader recognized the JOB card (for this job).
30	1E	SMF63RSD	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	SMF63UIF	8	EBCDIC	User-defined identification field (taken from common exit parameter area, not from USER=parameter on job statement).
42	2A	SMF63FDT	1	binary	Record creator/entry type indicator Bit Meaning When Set 0 New definition 1 Altered definition 2-5 Reserved 6 Path defined or altered 7 Alternate index defined or altered.
43	2B	SMF63TYP	1	binary	Entry type indicator Bit Meaning When Set 0 VSAM cluster 1 VSAM data component 2 VSAM index component 3 VSAM catalog 4 Non-VSAM data set 5 Generation data group 6 Alias 7 Reserved.
44	2C	SMF63NSZ	2	binary	Size of new catalog record. Include the contents of this field when estimating the additional storage required by SMF. A VSAM catalog record is contained in one or more physical catalog records. This field with offset 46 are the sums of the sizes of the physical catalog records that constitute the total logical VSAM catalog record.
46	2E	SMF63OSZ	2	binary	Size of old catalog record. This field contains the size of the old records before they were altered. Include the contents of this field when estimating the additional storage required by SMF.
48	30	SMF63CNM	44	EBCDIC	Name of catalog in which the entry is defined.
92	5C	SMF63ENM	44	EBCDIC	Entry name.
136	88	SMF63NCR	variable	binary	New catalog record followed by old catalog record. For the new catalog record, the complete new entry is recorded. For the old catalog record, this field contains only those old records that were altered; it shows what these records were before they were altered.

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