Hi,
I am using message broker 7.0.0.2. All my queue have a backout queue set to ESB_BACKOUT. Now I need to sort of retry these failed messages, but I am not sure how to identify where the message originated.
Please help, do I need to have a different backout queue, is there any other way to identify the originating queue so that the message can be sent back and retried?
I am totally new to MQ and not sure if there is any MQ automatic retry and how to setup backout queue's
Thanks |

You need individual backout queues.
You need to reexamine the use cases for actually doing retry. Broker already does a series of automatic retries before it sends anything to a backout queue. So you need to understand how that works, and then determine (for each message type) whether that is sufficient or whether it even makes any sense to retry a message after some interval. |

| I see. So I can make that design decision a little later, and implement it. For now I need a way to identify these messages and some how put them back into the system, manually or melodramatically. So On there MQMD I will not have anything like Source Queue or is that only available on the message tree at runtime? |

There will be nothing.
Unless you add it.
Which is very hard to do if you are letting Broker handle the backout.
Or unless you create individual queues.
If you have a stack of messages on your queue right now, and you need to retry them all, you need to *manually* *read* them all and then *determine* based on your knowledge of the system where they came from.
You have to do this based on the *content* of the message, not on anything in any headers. |
