If you are not familiar with GroupWise WebAccess, review GroupWise WebAccess Overview
in Installing GroupWise WebAccess
in the GroupWise 7 Installation Guide.
As you plan WebAccess in a clustering environment, you must keep in mind that you will plan and set up two WebAccess components:
WebAccess Agent (gwinter) that will be associated with a domain in your GroupWise system
WebAccess Application (a Java servlet) that will be added to your Web server (Apache). The WebAccess Application is currently not supported on a cluster resource.
You install the WebAccess Agent on each node in the cluster. You install the WebAccess Application to your Web server, which must not be clustered. This means that the WebAccess client login to the Web server at the following URL:
http://secondary_IP_address/gw/webacc
is available only when the Web server is running.
