This document discusses various features and techniques for duplicating and transporting Oracle databases using RMAN, including: 1. RMAN can duplicate a database without backups by using network-enabled duplication and the duplicate database will have its own unique DBID. Files names and locations may differ between the source and duplicate databases. 2. When duplicating a database, RMAN generates a unique DBID, creates a new control file, restores backups, and opens the duplicate database with resetlogs. 3. A database can be duplicated to a remote host or to a point in time in the past. Specific tablespaces, backups, or platforms can be excluded. The entire database or individual tablespaces can be transported
