Make sure that you can execute the following command from each of the
existing nodes of your cluster where the host_name is the public network
name of the new node:
NET USE \\
host_name
\C$
You have the required administrative privileges on each node if the operating
system responds with:
Command completed successfully.
NOTE: If you are using ASM, then make sure that the new nodes can access the
ASM disks with the same permissions as the existing nodes.
NOTE: If you are using Oracle Cluster File Systems, then make sure that the new
nodes can access the cluster file systems in the same way that the other nodes
access them.
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 below:
1
Adding Nodes at the Oracle Clusterware Layer
2
Adding Nodes at the Oracle RAC Database Layer
3
