Hi all,

I need to delete my tape datasets.

1. The online manuals say that I should'nt use IEFBR14 ( says it can only be used for DASD based data sets). Why?

2. It also goes onto suggest that I should use IEHPROGM. Can some one please tell me the i/p o/p parameters for this program.

3. Can we use IDCAMS? How?

4. Any other suggestions?

Thank you so much!

In option 3.4 we just use "U".

In IDCAMS, we just use:

Tape datasets are not really deleted, the volumes just expire and get reused.
You may:

- uncatalog it using IEHPROGM or IDCAMS or ISPF (this might cause the tape to expire in some shops)

- update the EXPIRE DATE to cause it to expire sooner (this function may be restricted)

Using IEFBR14 may cause a tape mount, which is unnecessary.

Hey guys!

Thanks a Lot!

I wrote a jcl with the IDCAMS utility (from one of the ibm.pulib manuals).
With instream as - delete tape.data.set

so does this mean - that my tapes have been uncataloged and placed in the
scratch heap ?
subsequently i had to rewrite data onto tapes with the name as before ie
tape.data.set
so does that mean that fresh tapes are used when the tape.data.set is re-created/cataloged?

just curious...

Thanks again!

Also, can we use HDELETE for deletion of data from a tape and subsequent rewriting data onto the same tape ( I'm not sure if I am using the right terms).
Let me rephrase my question -
What does HDELETE do? How does it function?
