Hi Yesterday i lost the catalog and there were not controlfile autobackups and also no dbid just a backupset lying on the disk. I did vaguely remember from the Oracle Press book by Robert Freeman which asked me to use the sys.dbms_backup_restore package to restore the controlfile. But i still searched and came across the following metalink Note:403883.1 which tells me how to restore a controlfile from backupset using a simple command like restore controlfile from '/mnt/RMAN_DISK_BACKUP/BKPDB08/c-xxx-xxx-xx'; and the controlfile was restored my question in such a sceanrio whats the use of the package sys.dbms_backup_restore ? (my only guess is sys.dbms_backup_restore can restore from a tape too) Any other ideas did my favourite backup and recovery book miss this or i missed it in the book ? regards Hrishy -- //www.freelists.org/webpage/oracle-l
