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.
To add a node to an existing cluster:
• Add the node to the network layer.
• Configure the shared storage.
• Add the node to the clusterware, database, and 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 clusterware layers.
For more information about adding an additional node to an existing cluster, see the document titled
Oracle Real Application Clusters 10g Administration located 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 Red Hat Enterprise Linux operating system on the new node. See "Installing and
Configuring Red Hat Enterprise Linux."
2 Configure the public and private networks on the new node. See "Configuring the Public and Private
Networks."
3 Verify that each node can detect the storage LUNs or logical disks. See "Verifying the Storage
Configuration."
Configuring the Shared Storage on the New Node
To extend an existing RAC database to your new nodes, configure storage for the new nodes so that the
storage is the same as on the existing nodes. This section provides the appropriate procedures for either
ASM or OCFS.
