Adding and Deleting Cluster Nodes for 11g

Adding Cluster Nodes for 11g

Prerequisite Steps for Adding Cluster Nodes

Make physical connections.
Install the operating system.
Create Oracle users.
Ensure that SSH is configured on the node.
Verify the hardware and operating system installations with the Cluster Verification Utility (CVU).

cluvfy comp peer [-refnode ref_node] -n node_list [-orainv orainventory_group] [-osdba osdba_group] [-verbose]

Adding a Cluster Node on Linux and UNIX Systems

Verify the integrity of the cluster and new nodes:

~]$ cluvfy comp peer -refnode oracle11grac01 -n oracle11grac03 -orainv oinstall -osdba dba -verbose

~]$ cluvfy stage -pre nodeadd -n oracle11grac03 -verbose

To extend the Grid Infrastructure home to the new nodes.

If you are not using GNS, run the following command:

~]$ export IGNORE_PREADDNODE_CHECKS=Y

~]$ $ORACLE_HOME/oui/bin/addNode.sh "CLUSTER_NEW_NODES={oracle11grac03}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={oracle11grac03-vip}"
