PURPOSE:To localize the faulty wave and range of an online system by operating the garbage collection of a task at which a fault occurs. CONSTITUTION:This system is equipped with a task initialization setting part 13 which operates an interruption register for the transition of a control when the fault occurs at the task in a center, and a task recovery part 14 which operates the garbage collection of the task in which the fault occurs. Also an abort library part 15 which calls the task recovery part 14 when the fault occurs at the task, and a representative task part 16 which prepares the task again are provided. The task recovery part 14 operates the garbage collection as the processings such as the return of a memory kept by the task at which the fault occurs, the close of a file, and a lock release, and then the representative task part 16 prepares the task again. Thus, only the pertinent task can be saved without interrupting the online system, and the faulty wave and range of the online system can be localized. |
