Abstract
In a redundant server network system, failover services for a failed server are provided by a survivor server belonging to a common failover group. At startup of a local server process running on the survivor server, a context is created for the local server and for each remote server belonging to the same failover group as the local server. At startup the context of the local server is also activated. The local server process is configured to operate on and make decisions based upon activated contexts. Each context includes server specific configuration and control information. When the survivor server must provide failover services for a failed server belonging to its same failover group, the context corresponding to the failed remote server is activated.
