Oracle 11g New Feature - Duplicating a Oracle Database Using 11g RMAN Backup Location Option but Without Connection to Target or  Recovery Catalog We have Target Database name as ORCL And we are creating a duplicate database using RMAN Auxiliary Instance with name as AUXDB by using the backup location but without making connection to target database and recovery catalog database while the duplication process is running. Note :- This practical need same directory structures and it is performed on same server. Just the database name is different so we are converting the path with respect to dbname only.  Image Source - docs.oracle.com Your Target Database can be in any log mode. Take RMAN Backup based on your Database Log Mode.
