Abstract
A method is provided for ensuring transactional integrity of a system that includes a first subsystem and a second subsystem. The first subsystem receives a request to process a transaction. The first subsystem sends to the second subsystem the request to process a transaction. Each of the subsystems process the identical request. An indicia engine at each subsystem computes indicia of the outcome of the processing of the identical request. The indicia engine at the second subsystem sends its computed indicia to the first subsystem, and the indicia engine at the first subsystem compares its computed indicia with the indicia received from the second subsystem, and sends a transaction abort directive to the second subsystem when the comparison indicates that the computed indicia of the second subsystem does not match the computed indicia of the first subsystem, thereby indicating a lack of transactional integrity in one or both of the first and second subsystems.
