Abstract:
In a server cluster including at least two server systems, a method of failing over a non-cluster-aware application from a first system to a second system of the cluster, comprising, locally maintaining application configuration information for the non-cluster-aware application on the first and second systems, the application configuration information separately maintained and used by an instance of the application executing on each system to determine at least part of an execution environment, running an instance of the non-cluster-aware application on the first system, the non-cluster-aware application instance making a change to the application configuration information, detecting the change to the application configuration information on the first system, and, in response to the change, making data representative of the change available to the second system, and running another instance of the non-cluster-aware application on the second system using the data made available thereto.
