Complete the prerequisite tasks for creating an application server cluster

Task 1 of 2 required to create an application server cluster.

This task describes all prerequisite tasks you must complete before you can create an application server cluster. These tasks include installing:

• A database server

• The application servers that form the cluster

• The load balancing device that handles connections to the servers in the cluster.

Perform the prerequisite tasks in this order:

1. Install the database to which the application servers connect.

2. Install the first application server (called Server1 in this example) and connect it to the database. The first server installed is the primary server in the cluster.

   This application server must host the Framework Application server role Entity that contains a logical, predefined set of components (system software or certified third-party software) deployed in the Data Center and Site Zones that provide specific functionality for the system.. This server can also host other server roles.

3. Install the additional application servers that are the other members of the cluster. Connect each of these servers to the same database server as Server1 installed in the previous step.

   Each of these additional application servers must host the same server roles as Server1. All server roles on each server must be of the same software version number as the server roles on Server1.

4. Activate the license on Server1 for the number of servers that operate as part of the cluster.

5. Install the load balancing device.

   Do NOT configure the servers to connect to the load balancing device now. The servers must be added to the cluster from Enterprise Manager before they are connected to the load balancing device, as noted in the next task.

   Configure the load balancer to listen for HTTP connections on port 80 and HTTPS (TLS) connections on port 443.

   An application server can have two Network Interface Cards (NICs) installed, where one NIC handles general communications and a second NIC serves as a backup.

   An application server you intend to cluster can have multiple NICs installed. In this case, ensure that the NIC that handles general communication on that server is the first connection accessed by network services.

   To ensure that a NIC is the first connections accessed by network services, do the following on the server:

   1. Open the Windows Control Panel.

   2. Select Network and Internet.

   3. Select Network and Sharing Center.

   4. Select Change Adapter Settings.

   5. Press the Alt key on the keyboard.

   6. Select Advanced, and then select the Advanced Settings menu.

   7. In the Adapters and Bindings tab, ensure that the NIC that handles general communications appears as the first connection in the Connections: box.

   8. Click OK.
