RMAN best practices for RAC

Managing backup and recovery for RAC databases is no different from managing those for single-instance databases. You do not need to expend additional efforts to work with RAC databases. The prime goal of this section is to discuss the essential configuration settings that are required for RAC databases. The following will be covered in detail:

• Configuring the Flash Recovery Area for a RAC database

• Instance recovery versus Crash recovery in RAC

• Configuring multiple channels

• Parallelism for backup and recovery in RAC

• Backing up a RAC database via RMAN
