Hi All,

Finally I did it. We are using TSM with tape backups and RMAN catalog database. Retention policy of the backup is 31 days and record keep time in control file is also same, 31 days. So I unregister the database from the catalog (so it deleted all the entries from the catalog and the tape backups untocuhed!) and re-registered again. I was able to re-register the database to the catalog with all the bacups since the record keep time (parameter value) is 31 days. Ran TDPOSYNC to sync the TSM with RMAN. Thats it.

Thanks to all!
