InterChange Server Express must be configured with environment-specific information for it to run. The necessary configuration for a typical implementation is done for you, using default values, when you run the Installer, as described in the WebSphere Business Integration Server Express Installation Guide.
However, if you need to make a modification in the configuration of InterChanger Server Express for your specific implementation, you can do so, using System Manager.
Configuration information for InterChanger Server Express is stored in XML format in a file named InterchangeSystem.cfg, which is stored in the product directory. You should not modify this file directly. Instead, if you need to make modifications to the configuration of InterChange Server Express, use System Manager. This chapter provides instructions for that.
