Using SMS Data Class Constructs

SMS Data Class names can be entered into a CA Vtape parmlib member to redirect a tape mount to a Virtual Device. Using a data class does not mean the data set is DFSMS-managed.

The advantages of this technique are the opportunity to use the many selection criteria available to SMS, such as DSN, UNIT, JOBNAME, and USERID and the centralization in SMS 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 SMS and ACS routines, see the IBM DFSMSdfp Storage Administration Reference.
