48 Adding a New Node to a Oracle 11g RAC Cluster
Now the node(s) is ready to be added to an existing cluster. The steps to add a
node to an existing cluster can be summarized as:
1
"Adding Nodes at the Oracle Clusterware Layer" on page 48.
2 "Adding Nodes at the Oracle RAC Database Layer" on page 49.
3 "Adding Database Instances to New Nodes" on page 50.
Adding Nodes at the Oracle Clusterware Layer
Perform the following steps:
1
On one of the existing nodes, go to the CRS home\oui\bin directory. Run
the
addNode.bat script to start the OUI.
2 The OUI runs in the add node mode and the OUI Welcome page is
displayed. Click
Next and the Specify Cluster Nodes for Node Addition
page is displayed.
3 The upper table on the Specify Cluster Nodes for Node Addition page
shows the existing nodes associated with the CRS home from which you
launched the OUI. Use the lower table to enter the public and private
node names of the new nodes.
4 If all the checks succeed, then the OUI displays the Node Addition
Summary
page.
5 Click Next and the OUI displays the Cluster Node Addition Progress page.
6 On completion, click Exit to end the OUI session. After the OUI displays
the
End of Node Addition page, click Exit to end the OUI session.
7 Execute the following command to identify the node names and node
numbers that are currently in use:
CRS home\bin\olsnodes -n
8
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
