SMF Type 64 Record

This table shows the record layout for type 64 SMF records
(VSAM Component or Cluster Status).

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

Purpose: Record type 64 is written when:
1. A VSAM component or cluster is closed,
2. VSAM must switch to another volume to continue to read or write,
3. There is no more space available for VSAM to continue processing.

If a cluster is closed, one record is written for each component in the cluster.

Record type 64 indicates why the record was created (a component was closed, another volume was switched to, or no additional space was available). It describes the device and volume(s) on which the object is stored, and gives the extents of the object on the volume(s). It gives statistics about various processing events that have occurred since the object was defined, such as the number of records in the data component, the number of records that were inserted, and the number of control intervals that were split.

This record identifies the job by job log identification and user identification. The job name, time, and date that the reader recognized the JOB card (for this job) constitute the job log identification.

It's easy to report on SMF 64 data! (Jump to sample reports)

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.

Sample Report from SMF 64 Records
Showing Statistics for VSAM Clusters/Components

The sample SMF report below was created with Spectrum SMF Writer, the low-cost 4GL SMF report writer.

In this report, we read as input the SMF file and select just the type 64 VSAM statistics records. (See SMF 64 record layout.) The report shows various VSAM statistics as of OPEN time. The statistics include number of extents, number of logical records, cumulative number of records inserted and deleted, and the cumulative number of control interval and control area splits, etc.

All of this with just a few lines of code!
