Abstract

To provide a resource management system capable of stably providing most recently updated resource information at a high speed. A resource information update unit collects resource information from a plurality of agents by means of agent connection management unit according to an update schedule of resource information stored in a schedule storage unit, and stores the same in a resource information storage unit. A retrieval processing unit accesses the resource information storage unit to acquire retrieval results of resource information. A static schedule generation unit selects update interval for each of resource information, generates a static schedule, and store the same in the schedule storage unit.
