What Must I Do Before I Begin?

Make sure that you have addressed each of the items on the panel before you attempt to configure CBR.

Check the following:

  • Make sure that the CBR workstation (front end machine) can ping each of the server workstations (back end machines).
  • Make sure that each of the server workstations can ping the CBR workstation.
  • Make sure that the servers are operational. Use a Web browser to request pages directly from each server.
  • Obtain an valid IP address for each cluster of servers that will be set up. This is the cluster address. The cluster address will be used by a client to connect to the servers in a cluster.
    For example: Name = www.intersplash.com IP = 9.67.67.104
  • Install CBR on the front end machine according to the instructions for your operating system in the Load Balancer Administration Guide

Using the Caching Proxy

The CBR component works with IBM's Caching Proxy proxy server to load balance traffic based on the content of a client's URL request. Follow these steps to configure and start the Caching Proxy. You must complete these steps before you can successfully create a configuration that will proxy HTTP traffic:

  • Install the Caching Proxy (a part of the WebSphere Edge Server) according to the online directions provided with the product.
  • Configure the Caching Proxy by editing the Caching Proxy's configuration file as specified for your operating system in the Load Balancer Administration Guide
  • Start the Caching Proxy as appropriate for your operating system.
