Method and system for information exchange utilizing an asynchronous persistent store protocol

A system is provided for facilitating the exchange of information between interconnected processors in environments such as distributed computing environments and message-oriented middleware environments. A source sends input to the target. A manager in communication with both the source and the target receives the input from the source, initiates a storage of the input and forwards the input to the target. If the manager receives output from the target before completion of the input storage, the manager cancels the input storage because it is no longer needed to ensure system reliability. Upon receiving output from the target, the manager initiates a storage of the output and forwards the output to the source. If the manager receives acknowledgement from the source that the target output has been received before completion of the output storage, the manager cancels the output storage because it is no longer needed to ensure system reliability.
