Thanks RA
No good saying wrong and posting a link, tell us what is right.
Anyway…
suspend the messages in the queue
export the messages in the queue
copy the exported messages to the replay directory
remove the messages in the queue (the suspended messages)
When you export messages from a queue, you don’t remove the messages from the queue. After you export the messages and successfully resubmit them by using the Replay directory, you should remove the suspended messages to avoid duplicate message delivery.
