This invention describes an asynchronous transaction recovery protocol that coordinates communications between different subsystems with execution in distributed DB/DC systems. To meet the increasing requirements for high availability, online transaction processing systems are being designed with mechanisms that allow rapid recovery from failure. System recovery includes not only preservation of database integrity through database recovery, but also transaction recovery, that is, the operations performed after failure to restore and continue processing of all affected messages. In a distributed DB/DC environment, several DB (database management) and DC (data communication management) subsystems are connected together.
