We have been backing up an oracle database with RMAN successfully for a few months now. A couple of weeks ago the DBA decided to rebuild the production database that has been backed up. They proceeded to build this new instance as a different name and once set up, export and import the data into this new database. When they finished, they renamed the instance to reflect to correct name. To get the RMAN backup to work, they unregistered the old instance and reregistered the new instance ID. The problem is that they didn't clean up all the old backups prior to unregistering the old instance. How can I manually remove the old backups from TSM since it seems that RMAN doesn't know about them anymore?
Thanks Mark
