Reply with quote

Hi friends,

I changed something in dsndr.dsnex dataset and saved it.
Actually I don't need this change.
Now I want to restore dsndr.dsnex dataset from tape and overwrite it in DASD using JCL.

Please help me.

What kind of back up do you have? You did back it up before making the change, right?

If you post the jcl that created the tape with the file on it, we can help with restoring it.

It might work to rename the file and then "HRECOVER dsn", If the file has been backed up by DFSMShsm.
