Using DFSMS Data Class Constructs

Use DFSMS Data Class names to redirect a tape mount to a CA Vtape Virtual Device. Using a data class does not mean that the data set is DFSMS-managed.

The advantages of this technique are the opportunity to use the many selection criteria available to DFSMS (DSN, UNIT, JOBNAME, and USERID) and the centralization in DFSMS of all redirection control for both DASD and tape processing.

The disadvantages of this technique are the need for coding changes in the ACS routines, the required security to accomplish such a change, and the increase in complexity of the ACS routines.

For information on using DFSMS and ACS routines, see the IBM DFSMSdfp Storage Administration Reference.
