PURPOSE:To make the information contents for taking over irreducible minimum and to standardize various processings for taking over in the processing system taking over inter multiple sub-system in the data processor realizing fault tolerant while multiplying the sub-system. CONSTITUTION:At the time of normal processing, the persistent insurance information, atomicity insurance information, and non-indenpotent processing insurance information are written in the prescribed area by using a first information writing means 13, second information writing means 14, and the third information writing means 15. At the time of taking over the processing due to the fault generation, the persistent insurance information, atomicity insurance information, and non-idenpotent processing insurance information are read by the first information reading means 16, the second information reading means 17, and the third information reading means 18. Thus, the effective taking over of the processing can be performed by the irreducible minimum taking over information. |
