29.2 IEBCOPY
IEBCOPY is a utility program used to make copies of, and to maintain,
partitioned data sets. In addition to the copy function, IEBCOPY performs the
following maintenance operations:
partitioned data sets. In addition to the copy function, IEBCOPY performs the
following maintenance operations:
•
Compression - the members of a partitioned data set are moved together
(compressed) to eliminate the unused space that results from changing
existing members.

existing members.
•
Merge - two or more partitioned data sets are merged into a third data set.
Information on IEBCOPY is provided in
DFSMS/MVS Utilities, SC26-4926.
29.3 IDCAMS
IDCAMS (Access Method Services) is a utility program that is used to manipulate
all access methods except partitioned. IDCAMS is recommended for use with
SMS managed data sets. This utility reads control statements and performs data
set functions such as creation, deletion, cataloging, and uncataloging. In
addition, IDCAMS performs the backup and restore functions for VSAM data sets.
