SMF Type 18 Record

This table shows the record layout for type 18 SMF records
(Rename Non-VSAM Data Set Status).

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

Purpose: Record type 18 is written when a non-VSAM data set defined by a DD statement (either explicitly or implicitly) is renamed. (When a DD statement defines a volume, all the data sets on that volume are implicitly defined.) This record contains the old data set name, new data set name, number of volumes, and volume serial numbers. Its length varies, depending upon the number of volumes for the data set

It's easy to report on SMF 18 data!
