EVENT PROCESSING SYSTEM, EVENT PROCESSING METHOD, LOCAL SYSTEM, DISPATCHER, AND PROGRAM STORAGE MEDIUM

摘要

Increase in the processing load of a dispatcher incident to replication of an event is minimized in an event processing system in which rule distributors are dispersed and disposed. An event processing system comprises a plurality of dispatchers (140) each transferring an event (201) to a local system (100), and a plurality of local systems (100) each transmitting the results (205) of event processing to an application server (160). When the number of times that the event (201) matches both a dispatch rule (204) based on the processing rule (202) of a local system (100(LS1)) and a dispatch rule (204) based on the processing rule (202) of a local system (100(LS2)) exceeds a predetermined threshold in the dispatcher (140), the processing rule (202) of the local system (100(LS1)) is moved to the local system (100(LS2)), or the processing rule (202) of the local system (100(LS2)) is moved to the local system (100(LS1)).
