Abstract

The transition of a use resource amount is predicted from the transition of a transaction occurrence amount for each module by using a function that expresses a correlation between a past transaction processing amount and a past use resource amount in a data processing system. After this, an allocation resource amount for each module is automatically fluctuated in accordance with the transition of the predicted use resource amount.
