Adding and Removing Nodes

This section describes the steps to add a node to an existing cluster and

the steps to remove a node from a cluster.

NOTE: The new node must have the same hardware and operating system

configuration as the existing node(s).

To add a node to an existing cluster:

• Add the node to the network layer.

• Configure shared storage.

• Add the node to Oracle Clusterware, database, and the database instance

layers.

To remove a node from an existing cluster, reverse the process by removing the

node from the database instance, the database, and the Oracle Clusterware layers.

For more information about adding an additional node to an existing cluster,

see the

Oracle Real Application Clusters 11g Administration

document on

the Oracle website at

oracle.com

Adding a New Node to the Network Layer

To add a new node to the network layer:

Install the Enterprise Linux operating system on the new node. See

the

Oracle Database on Enterprise Linux x86_64 Operating System

and Hardware Installation

for more information.

Configure the public and private networks on the new node.

See the

Oracle Database on Enterprise Linux x86_64 Storage and

Networking Guide

Verify that each node can detect the storage LUNs or logical disks.
