Using copy data set output descriptors

An output descriptor describes the general characteristics of the copy data set, whether it is a disk data set or a tape data set.

Following is a list of these characteristics:

  • The disk or tape unit name
  • MVS cataloging requirements for the data set
  • A model DCB
  • A generic data set name
  • Largest number of volumes expected to be used
  • SMS class information
  • For disk data sets:
    • Volume information
    • Disk space information
    • Optional data set expiration
    • Optional data set expiration
  • For tape data sets:
    • A stacked tape indicator
    • Optional allocation using a DD statement
    • Optional data compression
    • The data set retention period
    • The data set expiration date

An output descriptor specifies either a disk data set or a tape data set; it cannot specify both.
