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!
