What Is The Difference Between Persistent And Non Persistent Messages? |
|
Answer» In Web Sphere MQ, messages can be either persistent or NON persistent. Persistent messages are LOGGED and can be recovered in the event of a WebSphere MQ failure. Thus, persistent messages are guaranteed to be delivered once and only once. Nonpersistent messages are not logged. Web Sphere still GUARANTEES to deliver them not more than once, but it does not promise to deliver them once. In Web Sphere MQ, messages can be either persistent or non persistent.
