Replica instances use the primary instance IPv4 hostname and IP address to communicate with the primary instance. If you change the primary instance hostname or IP address, you must provide the new network settings to each replica instance in the deployment.
Before you begin
You must be a Super Admin.
On the replica instance, log on to the Operations Console.
Click Administration > Network > Update Primary Hostname.
If prompted, enter your Super Admin User ID and password.
In the Primary Hostname field, enter the primary instance hostname.
Click Test Connection. The system resolves the hostname, and updates the Primary IP Address field, if necessary.
