Distributed transaction processing system

摘要

An infrastructure and method for processing a transaction using a plurality of target systems. The method includes: generating a request from a source system, wherein the request includes an initial identifier and a counter value; submitting the request to at least two target systems; processing the request at a first target system and ignoring the request at a second target system based on the initial identifier; submitting a resubmitted request to the at least two target systems if a timely response is not received by the source system, wherein the resubmitted request includes an incremented counter value; and processing the resubmitted request by only one of the first and second target systems based on the incremented counter value.
