High availability is obtained for the deployment and undeployment of application views by placing a redundant JMX server on each server in a cluster of servers for an application integration system. Each redundant JMX server can manage deployment work for the cluster, and is capable of sending a JMX notification to every other server in the cluster relating to the deployment work, such as a deploy, undeploy, or processing notification. While an administration server can manage the other servers in the cluster, the redundant JMX servers are capable of managing deployment work for the cluster in the event of a failure of the administration server. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

High availability application view deployment

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.

System and method for providing highly available processing of asynchronous service requests

High availability event forwarding can be obtained utilizing distributed queues in a server cluster. Each server can receive an event from a data system, such as a database or SAP&#x2122; system. Event queues exist on servers in the cluster can store an event until, for example, the event is delivered to a user or retrieved for processing. An event processor examines the load of each event queue and selects the event queue with the lightest load. The event processor generates an alias for the selected queue, such that a user, integration system, or client application does not need to know the identity of the physical queue storing the event, but only needs to refer to the 'distributed queue' or alias. After a physical queue is selected and an alias assigned, the event is forwarded to the selected queue.
