B.2 RMAN Compatibility Matrix

In general, the rules of RMAN compatibility are as follows:

Table B-1 shows version requirements for RMAN components. Note the following conventions when interpreting this table:

When using an older version of the RMAN client with a newer version of the database, you do not get the features of the newer version. For example, when using the Oracle9i RMAN client to back up an Oracle Release 10g database, you will not have access to features like the flash recovery area, flashback database, TSPITR with an RMAN-managed auxiliary instance, or recovery through resetlogs.

B.2.1 Cross-Version Compatibility of Recovery Catalog Exports and Imports

Exports of the recovery catalog are often used as a way to backup its contents. When planning to use Oracle export utilities to back up the recovery catalog, refer to Oracle Database Utilities for details on compatibility issues surrounding the use of database exports across versions of Oracle. Exports from a later version of Oracle cannot be imported into databases running under earlier versions of Oracle. You must export your recovery catalog data using the export utility from the earliest version of Oracle that you need to use for a recovery catalog.

For example, if you want to export recovery catalog data from a 9.2.0.5 database and you expect to import it into an 8.1.7.4 version of Oracle for disaster recovery, you must use the export utility from the 8.1.7.4 release of Oracle to perform the export operation. Otherwise, the import operation will fail.
