Abstract
Highly-available processing of an asynchronous request can be accomplished in a single transaction. A distributed request queue receives a service request from a client application or application view client. A service processor is deployed on each node of a cluster containing the distributed request queue. A service processor pulls the service request from the request queue and invokes the service for the request, such as to an enterprise information system. If that service processor fails, another service processor in the cluster can service the request. The service processor receives a service response from the invoked service and forwards the service response to a distributed response queue. The distributed response queue holds the service response until the response is retrieved for the client application.
