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:
1 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.
2 Configure the public and private networks on the new node.
See the
Oracle Database on Enterprise Linux x86_64 Storage
and Networking Guide
.
3 Verify that each node can detect the storage LUNs or logical disks.
