Service application with pull notification

摘要

A method and implementing computer system is provided in which an event/notification channel of a service provider will send a brief "notification" of an arrival of a full or complete event/notification message which has been received in an event/notification channel, to all relevant pull consumers to inform the consumers that a more detailed message concerning an event being monitored has just arrived. The brief notification can be repeated for a predetermined number of times which is defined by the consumer. After sending a brief notification a predetermined number of times, the event/notification channel assumes that the pull consumer is not operational or no longer interested in the event and the event can then be discarded by the event/notification channel. The brief notification sent to the pull consumers may identify any attachments and the consumer may elect to receive the full event notification message without any or with only selected ones of the attachments. The consumer may direct the service provider to delete the attachments when the full notification is retrieved by the consumer, or the service provider may be programmed to automatically delete any attachments after a certain amount of time following retrieval of the event message by a consumer.
