Apparatus and method for controlling the delivery of an event message in a cluster system

摘要

An apparatus and a method for controlling the delivery of an event message of an event in a cluster system is provided. The apparatus delivers a received event message to the receivers registered for the event message in a specific order. The specific order is determined by a sequence number which is assigned to each of the receivers. Exchanging the sequence number between different nodes in a cluster enables delivery of the event in a specific order on a cluster-wide basis. Errors due to wrong event delivery are thereby prevented.
