I need to restore several tablespaces from an RMAN database backup (DB-1) to a different database (DB-2) on a different server than where they originated. These tablespaces currently do not exist in DB-2. Other tablespaces do exist, so datafiles will not have the same file number in the target database. Both source and target databases are 9iRAC. Can this be done? If so, how? Export/import isn't feasible due to file sizes and nature of data.
