Abstract: An event notification method for distributed processing systems provides reduction of queue space and event processing bandwidth associated with duplicate events such as a particular event that is duplicated and results in multiple event notifications propagated for multiple consumers. When a duplicate event notification is received at an input to an event notification queue, rather than queuing the duplicate event notification, a sequence number of the event notification already in the queue is updated to indicate to the event consumer, exactly how many duplicate events have been received. The timestamp of the updated event notification may also be set to the timestamp of the most recently received duplicate event notification.

Abstract: An event notification system for distributed processing systems provides for replacement of event identifiers associated with transient objects, such as processes within the processing system. An event management interface receives a notification from an event producer that an identifier of an event produced by the event producer is no longer valid. The event management interface blocks event notification for the event and dissociates an event registration entry associated with the event from the event identifier. A new event identifier is received from the event producer by the event management interface, which associates the registration entry with the new event identifier. Event notification for the event is then resumed.

Abstract: An event notification method for distributed processing systems provides remote and local node event notification in systems that require local registration of an event consumer in order produce an event notifications. To provide notification of an event occurring on a remote node, either event consumers on all nodes in the cluster register locally to receive event notifications and specify that the event is a cluster event, in which case the nodes send notification of their locally-occurring events to all nodes, or remote registrations are accepted at nodes and if a local consumer for the event is not present, a listener thread registers as an event consumer. The listener thread sends the event notifications to the remote nodes registered as consumers for the event by observing communication between the event producer and the local consumer, or receiving the event notifications directly if there is no local consumer.
