Sequence Numbers
Sequence numbers in the webMethods Broker system are designed to ensure that events are delivered reliably. The use of sequence numbers is optional, but is recommended if your application requires reliable delivery of events and is capable of storing and tracking these numbers.
Sequence numbers can be used between a publishing application and the Broker or between the Broker and a receiving application. Here are some common characteristics of both publish and receipt sequence numbers:
*Sequence numbers are 64-bit unsigned integers that contain non-zero values.
*Sequence numbers are always incremented and are assumed to never wrap back to 1.
