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.

Abstract: A process action status monitoring section monitors the cumulative CPU time and the idle time for a plurality of processes being executed on a time-sharing basis; those results are recorded in a process action status table. A process type determination section, based on the said cumulative CPU times, classifies those processes for which the cumulative CPU time is equal to or less than a certain threshold value as interactive type process, and classifies processes for which the cumulative CPU time exceeds the threshold value as non-interactive type processes. A non-interactive type process priority control section controls the priorities of processes judged to be non-interactive type processes by the process type judgement section. An interactive type process priority control section controls the priority of processes judged to be interactive type processes.
