APPLIANCE AND METHOD FOR CONTROLLING THE DELIVERY OF AN EVENT MESSAGE IN A CLUSTER SYSTEM

摘要

An appliance and a new method for controlling the delivery of an event message of an event in a cluster system is provided. The appliance comprises means for delivering 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 connected to each of the receivers. Exchanging the sequence number between different nodes on a cluster allows to deliver an event in a specific order on a cluster-wide basis. Thereby errors due to wrong event delivery are prevented.
