Getting Started Guide

6 Overview
Network Requirements
• It is recommended that you ensure each node contains at least three
network interface cards (NICs). One NIC for public network and two
NICs for private network to ensure high availability of the Oracle Real
Application Clusters (RAC).
• Public and private interface names must be the same on all nodes.
For example, if
eth0 is used as the public interface on node one, all other
nodes require
eth0 as the public interface.
• All public interfaces for each node should be able to communicate with all
nodes within the cluster.
• All private interfaces for each node should be able to communicate with all
nodes within the cluster.
• The hostname of each node must follow the RFC 952 standard
(
www.ietf.org/rfc/rfc952.txt ). Hostnames that include an underscore ("_")
are not permitted.
• Each node in the cluster requires the following IP address:
• One public IP address
• Two private IP address
• One virtual IP address
• Three single client access name (SCAN) addresses for the cluster
Operating System Requirements
• Red Hat Enterprise Linux 5.x AS x86_64
• Oracle Linux 5.x AS x86_64
