Dear friends,

I want to restore many datasets(with different Serial number) from one specific tape. How can we avoid many times tape mounting.

Thanks in advance,
Ramkumar

Hello and welcome to the forum,

How are there multiple serial numbers for one specific tape.

You need to re-post your request so that the question represents something that is possible.

If you are doing some amount of processing using a single tape volume as input, suggest you specify RETAIN in the jcl. If you are not familiar with RETAIN, there is a link to "IBM Manuals" at the top of the page and one of the manuals listed is the JCL Language Reference manual.

In case your restore program dynamically allocates the tape, it will probably be smart enough to mount the tape only once.

An alternative is to issue an MVS MOUNT command to load the tape on a drive permanently until you do an UNLOAD.
