This note explains the procedure of creating a Physical Standby database using 11g RMAN DUPLICATE FROM ACTIVE DATABASE feature which is now available in 11g Release 1 onwards. This enables us to create a physical standby database without having to take a backup of the primary database as a prerequisite step.
