Explanation: Assume that the source database prod is on host1 and stores its data files in a non-ASM file system. The control files for prod are located in /oracle/oradata/prod/. You want to duplicate the source database to database dupdb on remote host host2. You want to store the duplicate database files in ASM disk group +DISK1. After connecting RMAN to the target, duplicate, and recovery catalog databases, run the following RMAN script to duplicate the database. DUPLICATE TARGET DATABASE TO dupdb FROM ACTIVE DATABASE SPFILE PARAMETER_VALUE_CONVERT '/oracle/oradata/prod/', '+DISK1'SET DB_CREATE_FILE_DEST +DISK1;When the DUPLICATE command completes, the duplicate database is created, with data files, online redo log files, and control files in ASM disk group +DISK1.
