Real Application Clusters Database Configuration Scenario

A RAC database requires three components: cluster nodes, shared storage, and Oracle Clusterware. Although you can choose how many nodes your cluster should have and what type of shared storage to use, this appendix is based on one specific configuration, which is the recommended configuration for two-computer, or two-node, clusters. This recommended two-node configuration uses Automatic Storage Management (ASM) for storage and Recovery Manager (RMAN) for the backup and recovery strategy. In addition, the instructions for the Enterprise Edition interface tasks use the Enterprise Manager Database Control console. This appendix does not provide cluster database installation and configuration procedures.
