Claim:
A policy control method responsive to occurrence of a fault or abnormality in a computer to distinguish a fault occurrence place and a cause and take a measure by using policies, the policy control method comprising: conducting confirmation policy processing for acquiring confirmation item information from a storage apparatus, the confirmation item information indicating a condition every confirmation item to distinguish a cause at time of fault occurrence, reading out presumed cause information from the storage apparatus when a confirmation item value of a confirmation subject object satisfies a condition in the confirmation item information, the presumed cause information indicating a presumed cause corresponding to each pattern in the confirmation item information, and acquiring a presumed cause corresponding to the confirmation item information of the condition, and judging whether a probability of the presumed cause is greater than a probability of a cause for automatic execution; conducting execution policy processing for causing a processing apparatus to execute contents of a measure read out from execution policy information, the execution policy information indicating a measure against the acquired presumed cause; conducting evaluation policy processing for acquiring evaluation item information from the storage apparatus to evaluate a result of the measure, judging an effect of the executed measure on the basis of whether an evaluation item value of an evaluation subject object is in a stable operation range indicated by the evaluation item information, and storing a result of the judging in the storage apparatus; and controlling an autonomous policy cycle for causing the processing apparatus to conduct the confirmation policy processing, the execution policy processing and the evaluation policy processing in order.
