Apparatus and method for maintaining resource integrity without a unified transaction manager in a software environment

摘要

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.
