What is the difference between a dead letter Queue and a back out queue?
In WebSphere MQ terms and in terms of Application Servers.
All J2EE/JEE app servers have a MQ Provider do they also have a construct of a Dead Letter Queue or is that something specific to WebSphere MQ?
My understanding of a back out queue is as follows:
If MQ is unable to deliver the message to a destination after a specified number of attempts it moves the message to the back out queue.
I do not have a clear understanding of a Dead Letter queue.
Appreciate any assistance.
