I have a target database and RMAN which was taking hot backups daily. I had to rebuild the target database due to character set ut8 from usascii7. Now RMAN doesnt recognize the target database. Erorr message:
RMAN-20001 target database not found in recovery catalog

Cause: Target database is not found in the recovery catalog.

Action: Make sure that the target database is registered in the recovery catalog.

shall i re-register the target database to rman? or what do i do?
