Verifying the Setup

1. Install the load balancer plug-in. For detailed steps to install the plug-in, see Sun Java System Application Server 9.1 Installation Guide. During the installation, provide the path to the DAS certificate.

2. Log in to the Application Server Admin Console and create a new cluster. For steps to create a new cluster, refer to the Admin Console Online Help.

3. Create a new HTTP Load Balancer. While creating the load balancer, specify the FQDN of the web server host as the device host name, web server SSL Port as the device port and select the cluster you created in the previous step as the target. For detailed steps to create a new HTTP Load Balancer, refer to the Admin Console Online Help.

4. To verify that the communication between the DAS and the web server is working properly, in the Admin Console, navigate to the HTTP Load Balancers node and click the HTTP Load Balancer. In the Load Balancer Device Settings page that appears, press the Test Connection button.

   If you have not enabled the Automatically Apply Changes option while creating a load balancer, then you must manually export the load balancer configuration by going to the Export tab and clicking Apply Changes now.

5. If the test connection fails, be sure to check the Application Server domain logs and the web server logs to troubleshoot the problem. Also check if all the configuration steps have been performed correctly.
