SMF Type 48 Record

This table shows the record layout for type 48 SMF records
(JES2 SIGNOFF/Stop Line (BSC only)).

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

Purpose: Record type 48 is written when:

A $P LNEn command (to stop a line) is issued
A $E LNEn command (to restart a line) is issued, and
When a remote user signs off.

This record contains:

A record indicator
A remote name
A line name
A password
A line adapter address
The number of execute channel programs (EXCP)
Negative acknowledgements to write text
Data checks to read text
Time outs to read text.

The field names beginning with MDCTS are for SIGNOFF and contain session totals; the other fields are for $P LNEn commands and contain connection totals.

It's easy to report on SMF 48 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.
