PURPOSE:To prevent the down of a whole computer because of a program bug by removing application process executed in a precedent system computer becomes down from the application process group of the ensuing system computers and permits the ensuing system computer to be operated as the advance system ones. CONSTITUTION:The special application process group is execution-started by the ensuing system computers 2 and 3 at the point of time when it is delayed for a period fulfilling a prescribed condition from the point of time the execution of the precedent system computer 1 is started. Then, when the precedent system computer 1 becomes down, application process which is executed in the precedent system computer 1 is evaded from the application process group of the ensuing system computers 2 and 3 so as to permit the ensuing system computers 2 and 3 to be operated as the precedent system ones. Thus, the down of the whole computers 1-3 because of the program bug is prevented and the processing of a whole system can be continued. |
