Abstract:
A method of communicating with a remote node from a transaction processing system having a transaction manager, one or more application processes and two or more gateway processes for communicating with remote nodes, the method comprising the steps of: wherein each ofperforming work for a first transaction by a first application process, the first transaction having an associated global transaction identifier, wherein each of the application processes, including the first application process, is configured with a hashing function, wherein application of the hashing function to a particular global transaction identifier always identifies the same gateway process, and wherein each of the gateway processes has a global map that associates global transaction identifiers with local transaction identifiers; applying the hashing function to the global transaction identifier by the first application process so as to identify a first one of the gateway processes when the first application process desires to export the first transaction to a remote node; exporting the first transaction to the remote node; and storing the global transaction identifier to the global map of the first gateway process.
