Delivery Quality of Service
Message Brokers enable messages to be delivered to consumers in a volatile (at most once) or guaranteed (at least once) fashion. When you use webMethods Broker with an Integration Server, you can also specify exactly-once processing to ensure the end integration is executed once and only once. For information about exactly-once processing, see the Publish-Subscribe Developer’s Guide.
