Backing Up an Oracle Database

Backing up an Oracle database is accomplished just like any RMAN backup. The Database Administrator starts RMAN and a script written to use an MML. RMAN collects data from Oracle and sends it to the MML. The MML passes the data, along with the backup specifications it finds in the parameter file. DPX controls the movement of the data across the network to storage devices and keeps track of this information in the Catalog.

Note. In addition to the Catalog, you should set up RMAN to keep its own recovery catalog. See the Oracle documentation for more information on how and why to do this when using an MML.

Note. To ensure the integrity of point-in-time restore, the database must be in ARCHIVE LOG MODE before performing the backup.
