2.2.2.1 Configuring the Load Balancer

To configure the load balancer, complete these steps:

1. Create a pool of servers. You will assign this pool to virtual servers.

2. Add the addresses of the Oracle HTTP Server hosts to the pool. For example:

■ WEBHOST1:7777 ■ WEBHOST2:7777 3. Configure a virtual server in the load balancer for wc.mycompany.com:443. ■ For this virtual server, use your system’s frontend address as the virtual server address for example, wc.mycompany.com. The frontend address is the externally facing host name used by your system and that will be exposed in the Internet. ■ Configure this virtual server with port 80 and port 443. Any request that goes to port 80 should be redirected to port 443. ■ Specify ANY as the protocol. ■ Enable address and port translation. ■ Enable reset of connections when services andor nodes are down. ■ Assign the pool created in step 1 to the virtual server. ■ Create rules to filter out access to console and em on this virtual server.

4. Configure a virtual server in the load balancer for admin.mycompany.com:80.

■ For this virtual server, use your internal administration address as the virtual server address for example, admin.mycompany.com. This address is typically not externalized. ■ Specify HTTP as the protocol. ■ Enable address and port translation. ■ Enable reset of connections when services andor nodes are down. ■ Assign the pool created in step 1 to the virtual server.

5. Configure a virtual server in the load balancer for

wcinternal.mycompany.com:80. ■ For this virtual server, use your internal administration address as the virtual server address for example, wcinternal.mycompany.com. This address is typically not externalized. ■ Specify HTTP as the protocol. ■ Enable address and port translation. ■ Enable reset of connections when services andor nodes are down. ■ Assign the pool created in step 1 to the virtual server.

Configure monitors for the Oracle HTTP Server nodes to detect failures in these nodes. ■ Set up a monitor to regularly ping the URL context. ■ For the ping interval, specify a value that does not overload your system. You can try 5 seconds as a starting point. ■ For the timeout period, specify a value that can account for the longest time response that you can expect from your WebCenter system, that is, specify a value greater than the longest period of time any of your requests to HTTP servers can take.
