40.1. Preinstallation Steps

Before starting the Oracle RAC installation, you need to verify that your environment and cluster are properly configured to support it. The servers that will host the instances are referred to as nodes in the cluster. Each of the nodes should have external shared disks. Each node should have redundant switches to support failover requirements. Each node should have one private Internet Protocol (IP) address for private connections and one public IP address for client connections and connection failovers from other nodes. Oracle Database 10g provides a tool called VIPCA (Virtual IP Configuration Assistant) to support the configuration of your IP addresses.

Each node must support TCP/IP (Transmission Control Protocol/Internet Protocol) and a supported interconnect software protocol.
