9 Configuring Load Balancing

You can configure your WebLogic Server cluster to provide load balancing.

With the domain configuration complete, using the administration server and clustered managed servers, you need a method to proxy to forward to different managed servers for load balancing. You can implement a proxy server for WebLogic by using one of these mechanisms:

  • An instance of WebLogic Server and HttpClusterServlet. (See Using Web Server Plug-Ins with WebLogic Server.)

  • A third-party proxy server, such as Apache, Microsoft IIS, or Netscape IPlanet, with a WebLogic proxy plug-in. (See Using Web Server Plug-Ins with WebLogic Server.)

  • A hardware-based load balancer such as F5’s BigIP (see BIG-IP® Product Family) or other products (see Choosing a Hardware Load-Balancing Device).

Note: LiveCycle in a cluster environment supports only sticky sessions for load balancing. The WebLogic plug-in for Apache supports sticky sessions by default.
