  • Apparatus for maintaining resource integrity without a unified transaction manager in a software environment
    Patent number: 7448035
    Abstract: An apparatus and method for maintaining integrity of data in a software environment are provided. With the apparatus and method, the individual software resources associated with a transaction are identified and the processing of these resources is started. As the processing of these resources terminates, their associated APIs return messages indicating either that the software resource committed or was unable to commit and the reason why the software resource was unable to commit. Based on this reason, appropriate error resolution and recovery operations are performed and the transaction is resubmitted only to those software resources that were unable to commit. The software resources that already committed have their states maintained. In this way, roll back of committed software resources is avoided.
    Type: Grant

  • Method and apparatus for preventing duplicate transactions on batch mode failure recovery in a data processing system
    Patent number: 6799166
    Abstract: A method and apparatus for processing electronic transactions. A batch request is received, wherein the batch request includes a plurality of electronic transactions. A determination is then made as to whether the batch request has been processed. Responsive to a determination that a portion of the batch request has been processed, the plurality of electronic transactions is sent for processing. Responsive to a determination that a portion of the batch request has been processed, a signal is sent indicating a check for duplicate electronic transactions should be made with respect to the plurality of electronic transactions.
