<P>PROBLEM TO BE SOLVED: To provide a failure restoration device capable of reducing a handling time while suppressing a management cost. <P>SOLUTION: An operating state detection means 1 detects the operating state of a service execution means 10. A rule accumulation means 2 accumulates a plurality of failure handling rules including a condition expression for determining the operating state in the case of a failure in the service execution means 10, and the priority information of a handling command and a rule for the restoration or avoidance of the failure in this operating state. A handling method retrieval means 3 fetches a rule having a condition expression matched to the present operating state of the service execution means 10, successively tries it according to its priority information, and outputs the change information of an operating state which is predicted to be changed after the execution of the handling command to a state register 5. An effect determination means 6 compares the change information of the operating state held in the state register 6 with the operating state of the service execution means 10 after the execution of the handling command to determine the success or failure of the restoration or avoidance, and corrects the priority information according to the result. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
