Computer implemented method and system for processing an event notification within a notification infrastructure of a database system using a persistent queue

摘要

A computer implemented method for processing an event notification within a notification infrastructure of a database system based on a client specified quality of service designation. The designation may indicate reliable transmission in which case a persistent internal queue is used. The method includes enqueuing an event notification into a persistent internal queue of said database notification infrastructure provided the client specified quality of service designation indicates reliable event notification. The event monitor then notifies the specified subscribers of the event notification. The reliable quality of service designation can be made at event registrations.
