Adding New Servers in WebLogic

To add new servers in WebLogic:

Log in to the WebLogic Administration Console with the following URL:
http://<host_name>:<port>/console
In the Change Center pane, click Lock & Edit.
In the Domain Structure pane, click Environment and then click Servers.
Click New.
On the Create a New Server page, complete the following:
1. In the Server Name field, enter a name for the managed server.
2. In the Server Listen Address field, enter the hostname or IP Address of the remote server.
  Note: If you plan to add a new managed server on the same physical server as the Administration server, you can leave this field blank. This allows all local listening addresses on the server to be utilized.
3. In the Server Listen Port field, enter the port number from which you want to access the server instance.
  Tip: You can more easily manage and maintain the servers in your cluster by using the same port number across all of your managed servers.
4. Select Yes, make this server a member of an existing cluster.
5. Select a cluster.
6. Click Finish.
Click Activate Changes.
