Cataloged data sets z/OS DFSMS Using Magnetic Tapes SC23-6858-00 |
|
The operating system has facilities that automatically record the
following information about each of your data sets:
The information is indexed by the data set name and recorded on a direct access device in a logical structure called the catalog. You can retrieve a cataloged data set by specifying its name in the DD statement and omitting the volume serial. The system finds the associated information in the catalog and issues a command, to either the operator or the tape library, to mount the cartridge on a drive. |
