Adding a New Node to a Oracle 11g RAC Cluster 49
9 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 have completed the procedures in this section for adding nodes at
the Oracle Clusterware layer, you have successfully extended the CRS home
from your existing CRS home to the new nodes.
Adding Nodes at the Oracle RAC Database Layer
1 From the %ORACLE_HOME% \oui\bin , run the addNode.bat script. This
starts the OUI in the add node mode and displays the OUI
Welcome page.
Click
Next on the Welcome page and the OUI displays the Specify Cluster
Nodes for Node Addition
page.
2 The Specify Cluster Nodes for Node Addition page has a table showing
the existing nodes associated with the Oracle home from which you
launched the OUI. A node selection table is displayed on the bottom of
this page showing the nodes that are available for addition. Select the
nodes that you want to add and click
Next .
If all of the checks succeed, then the OUI displays the
Node Addition
Summary
page.
3 Click Finish and the OUI displays the Cluster Node Addition Progress
page.
4 After the OUI displays the End of Node Addition page, click Exit to end
the OUI session.
5 Execute the VIPCA utility from the bin subdirectory of the Oracle home
using the
-nodelist option with the following syntax that identifies the
complete set of nodes that are now part of your RAC database beginning
with Node1 and ending with Node
N :
vipca -nodelist Node1,Node2,Node3,...NodeN
6
Add a listener to the new node only by running the Net Configuration
Assistant (NetCA)
.
After completing the procedures in the previous section, the new nodes are
defined at the cluster database layer. New database instances can now be
added to the new nodes.
