Method for handling conversational transactions in a distributed processing environment

摘要

In a distributed processing system having a least an originating node and a responding node connected through a communication path, the responding node comprising a plurality of processors and a memory device and where each of these processors is capable of accessing information from a corresponding database residing within the memory device, the inventive method involves: storing context information for an associated conversational transaction using a first processor situated within the responding node wherein the context information is stored at a pre-defined address in a first database residing within the memory device and associated with the first processor; producing a first message using the first processor for transmission from the responding node over the communication path to the originating node wherein the first message contains a first transaction identifier field having a value that corresponds to the pre-defined address; generating within the originating node a second message for transmission from the originating node over the communication path to the responding node wherein the second message contains a second transaction identifier field having substantially the same value as the first transaction identifier filed; and accessing the record using a second processor located within the responding node in response to reception of the second message at the second processor by generating the pre-defined address within the second processor using the value of the second transaction identifier field so as to permit the second processor to incrementally process said conversational transaction within the responding node.
