Some of the most critical responsibilities of an Oracle DBA are ensuring that the database is backed up and that it can be restored in the event of a failure. This course covers using RMAN to back up and restore a RAC database, minimizing downtime after an outage, and maintaining archived redo log files in a RAC environment. This course is one of a series in the Skillsoft learning path that cover a portion of the objectives for exam 1Z0-068 Oracle Database 12c: RAC and Grid Infrastructure.

Oracle Recovery Manager
- list the benefits Oracle Recovery Manager (RMAN) provides for RAC
- configure spfile and controlfile backups in Oracle RAC
- describe why all cluster nodes should be able to access all backups
