Resetting the UADS catalog entry

After the UADS has been reformatted, you must reset the UADS catalog entry. Use one of the following methods:

To reset the UADS catalog entry using ISPF/PDF, enter option 3.2 and delete the old UADS, then rename the new UADS to the name of the old UADS.
To reset the UADS catalog entry using TSO/E commands, use the DELETE command to delete the old UADS, then use the RENAME command.
To reset the UADS catalog entry using access method services, use the IDCAMS utility. For information on how to use IDCAMS, see .
To reset the UADS catalog entry using a batch job, execute IEHPROGM as shown in Figure 1. The batch job:
1. Deletes the old UADS (SCRATCH)
2. Uncatalogs the old UADS (UNCATLG)
3. Renames the new UADS to the old UADS name (RENAME)
4. Catalogs the new UADS under the old UADS name (CATLG)
5. Uncatalogs the old UADS name (UNCATLG).
