Abstract
The present invention is directed to systems and methods for recovering from unplanned failures in object oriented computing environments. The systems and methods of the present invention recover from unplanned failures in an efficient manner by storing recovery information in recovery objects. During recovery operations from an unplanned failure, object instance methods (which were abnormally terminated by the unplanned failure) use the recovery information to identify committable actions which were executed prior to the unplanned failure. The object instance methods then execute committable actions which were not executed prior to the unplanned failure. Thus, according to the present invention, the committable actions which were executed prior to the unplanned failure are not re-executed, and the committable actions which were not executed prior to the planned failure are executed.
