11,880,356 - Multi-processor transaction-based validation architecture that compares indicia associated with matching transaction tags
Abstract:A method is provided for performing transaction processing in a system. The system includes a plurality of processors. Each processor executes a plurality of transactions. Two of the processors receive requests to process the same subset of the plurality of transactions and each of the two processors execute each of the requests to process the same subset of the plurality of transactions. Each of the two processors create local indicia from the outcome of each transaction in the same subset of the plurality of transactions. Each of the two processors assign a transaction tag to each of the local indicia, wherein the same transaction tag is assigned by each of the two processors executing the same transaction. The local indicia and the respectively assigned transaction tags from each of the two processors are queued. It is then detected when queued transaction tags from the two processors match each other. The local indicia associated with the matching transaction tags are then compared to each other. Remediation action is taken when the local indicia associated with matching transaction tags do not match each other.
