When you add a server to a cluster, you specify its Administration Server and port number. If the Administration Server contains information about more than one server, all its servers are added to the cluster. You can remove individual servers later.
If a remote Administration Server contains information about a cluster, the servers in the remote cluster are not added. The master Administration Server adds only those servers that are physically installed on the remote computer.
Make sure the master Administration Server is tuned on.
Access the Administration Server and choose the Cluster Mgmt tab.
Click the Add Server link.
Choose the protocol used by the remote Administration Server.
http for a normal Administration Server
https for a secure Administration Server
Enter the fully qualified domain name as it appears in the magnus.conf file of the remote server in the Admin Server Hostname field.
For example: plaza.sun.com
Enter the port number for the remote Administration Server.
Your master Administration Server now attempts to contact the remote server. This can take a few minutes. You will receive a message confirming the server is added to the cluster.
If you have two or more servers on different computers that use the same identifier, the server identifier and the hostname for each computer are displayed. When both server identifier and hostnames are the same, the port number is also displayed.
When you enable cluster control, the master of the cluster creates a number of files in the https-server-instance/config/cluster/server-name/https-server-name/ directory for each slave in the cluster. These files are not configurable.
