SMF Type 24 Record

This table shows the record layout for type 24 SMF records
(JES2 Spool Offload).

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

Purpose: Record type 24 is written whenever a job or SYSOUT data set is transmitted to or received from an offload data set. JES2 writes one type 24 record for each pre-processing job that is transmitted to an offload data set or received back to spool. Because one type 24 record is written for each SYSOUT data set header that is transmitted or received, multiple type 24 records can be expected for each post-processing job.

This record identifies the name, time and date of each job that has been transmitted or received. It includes specific information about jobs in a record subtype. For jobs not yet run, it reports job-related information such as job class and system affinity in both the job selection criteria section and in the system affinity section. For jobs that have already run, it reports information about SYSOUT data sets such as output group id and forms name in the SYSOUT selection criteria section. Record type 24 never contains both the job selection criteria section and the SYSOUT selection criteria section.

This record can be used with the subtype selectivity function.

It's easy to report on SMF 24 data!

SMF Spectrum Writer
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.
