ABSTRACT:
A method for increasing throughput of N-way central electronic complexes concurrently executing processes to selectively lockable data resources while maintaining coherency among replicates of the information state of any accessed resource. Throughput is increased by overlapping a resource lock request with the processing incidental to accessing the resource. Processes are granted locks to portions of the resource based on the interest state held by the central electronic complex in the resource. Messages are attached to locked resources and are distributed to the appropriate complexes by virtue of a list maintained by the central electronic complex holding sole interest in the resource. The central electronic complex distributing the messages must receive acknowledgement of the message reception before releasing the resource.
