A problem encountered during Oracle 10g clusterware Installation

After configuring nodes in Specify Cluster Configuration, click next:

The specified nodes are not clusterable

INFO: Query Returned:

Null

This is because ssh is not properly configured for trusted authentication: Although trusted authentication has been configured, Clusterware requires the public node name, private node name, and their corresponding aliases of each node in the hosts file, all are verified using ssh trusted authentication.

However, due to ssh features, during the first connection, the system will prompt whether to add a new key. If the corresponding keys of all the above names are not added in advance, Clusterware will report the above error.

The solution is simple: perform an ssh connection to each name and add the key to each node.
