CA Dynam for VSE User Guide

IBM Virtual Tape Facility (VTAPE) Support
Versions other than the most current can be specified on the DSN=data set
name parameter:
• A relative version can be accessed by appending .(-nn) to the data set
name. For example,
DSN='TAPE.(-2)'
• An absolute version can be accessed by appending ,G=nn to the data set
name. For example,
DSN='TAPE,G=3'
Output Processing
The full IBM VTAPE command must be specified for output processing. CA
Dynam/T saves the specified VTAPE information at Job Control time. The
VTAPE information is then stored in the catalog and associated with the
volume being created at open output time for controlled tapes.
CUU Assignment
The VTAPE CUU must be pre-assigned for both controlled and uncontrolled
output tapes. CA Dynam/T does not allow the operator to assign a VTAPE
CUU when responding to a mount message.
However, CA Dynam/T will AVR the VTAPE and dynamically make the
assignment, if a specific volume is requested for output in any of the following
situations:
• Other than file one of a multifile set
• A cycle controlled volume
• DISP=OLD processing
Catalog Information, Panels, and Reports
VTAPE versions can be added manually to the catalog using the DYNCAT ADD
command by specifying the VTAPLOC and VTAPFILE parameters. For more
information about using the DYNCAT ADD command for VTAPE support, see
ADD Command in the chapter “Maintaining the Catalog—DYNCAT Program.”
VTAPE volumes are denoted by a (V) appended to the volser for most online
panels and batch reports.
