Testing the configuration
Keep these points in mind to ensure reliable operations in the cluster:
-
Start database instances at the same time on all desired nodes. This verification confirms multiple node access to the database.
-
Start listeners on all nodes using the host names specified in the
listener.ora
configuration files. This action may require configuring IP aliases on servers.
-
Verify all instances are registered with all the listeners. This critical step ensures clients can connect to any listener to access any instance.
-
Verify the client systems can access the new database.
