HIGH AVAILABILITY FOR EVENT FORWARDING
First Claim
1. A system for high availability message forwarding comprising:
- a cluster of servers, each server in the cluster adapted to receive a message;
message queues on at least some of the servers in said cluster of servers, the message queues adapted to store the message; and
a message processor on the server that stored the message in said cluster of servers, the message processor adapted to determine the appropriate message queue on a different server and forward the message to that message queue, wherein the message processor and message queue is part of a Java Messaging Service system.

Abstract
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™ 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.
