Abstract: In accordance with one embodiment of the present invention, a method and system for communicating between a plurality of disparate hosts and an order processing system includes generating orders at each of the disparate hosts. The orders are transmitted from each of the hosts to a shared message handler using relational database statements. At the shared message handler, the orders are stored in a relational database table structure using relational database statements. The orders are transmitted from the relational database table structure of the shared message handler to the order processing system. Responses to the orders are received from the order processing system at the shared message handler. Each of the responses is associated with a corresponding order. The status of the corresponding orders are updated based on the responses and provided to the disparate hosts.

Abstract: A recovery method for a resource management system having a message handler for communicating orders from a plurality of disparate hosts to an order processing system for assignment to remote resources includes shutting down the order processing system and the message handler. A restored order processing system is generated by replacing a current version of the order processing system with a previously saved version. The restored order processing system is restarted, as is the message handler. Each order in the restored processing system is set to pending. Orders in the restored order processing system that were closed subsequent to a time of the previously saved version are identified and deleted from the restored order processing system. Orders in the message handler that were transmitted from the message handler to the order processing system subsequent to the time of the previously saved version are identified.
