36 Adding a New Node to an Existing Oracle 10g RAC Cluster
Adding Nodes at the Oracle Clusterware Layer
1 On one of the existing nodes, navigate to the CRS home\oui\bin directory.
Run the
addNode.bat script to start the Oracle Universal Installer (OUI) .
2 The OUI runs in the add node mode and displays the OUI Welcome window.
3 Click Next. The Specify Cluster Nodes for Node Addition window is
displayed.
The upper table on the
Specify Cluster Nodes for Node Addition window
displays the existing nodes associated with the CRS home from which you
launched the OUI.
4 Enter the public and private node names of the new nodes in the
lower table.
If all the checks succeed, then the OUI displays the
Node Addition Summary window.
5 Click Next. The OUI displays the Cluster Node Addition Progress window.
6 On completion, click Exit to end the OUI session.
7 After the OUI displays the End of Node Addition window, click Exit to
end the OUI session.
8 Execute the following command to identify the node names and node
numbers that are currently in use:
CRS home\bin\olsnodes -n
9
Execute the crssetup.exe command using the next available node
names and node numbers to add CRS information for the new nodes.
For example:
crssetup.exe add -nn publicnode3,3 -pn pvtnode3,3
–vn vipnode3,3
10
Execute the racgons utility from the bin subdirectory of the CRS home to
configure the Oracle Notification Services (ONS) port number as follows:
racgons add_config new_node_name:4948
After you complete the procedures in this section and add nodes at the Oracle
Clusterware layer, you can successfully extend the CRS home from your
existing CRS home to the new nodes.
