Hi,
We had a rather irritating incident recently where a script to redirect some remote queue definitions had been run inadvertently.
The result was that 100 messages ended up on the wrong transmission queue with the incorrect addressing details.
Now, although all the messages were on the same transmission queue, they were destined for three seperate remote queues. i.e. the messages on the xmitq had come from three different RQDs.
My task was to take the messages from the transmission queue, remove their addressing information and place them on the correct three RQDs so that they would be delivered correctly. This meant manually examining each message stripping its XMITQ header and placing the message on the correct RQD.
We found a workaround in the end, to have the messages resent, so we did not move the messages in the end.
My question is, what tool or procedure should I have used? I tried using RFHUTIL and Qpasa both of which didn't seem to allow us to complete the task quickly.
The only way I found to do it was to save each message to a seperate file in RFHUTIL, then load it back to the new queue specifying RFHUTIL to strip the header.
Any ideas?
Thanks

1. the messages are on a xmitq
2. define the related channel with 1 byte maxmessagelength
3. start the channel
4. your messages get moved by the mca from the xmitq to the dead letter queue because they can not be sent over the 1 byte channel (make sure the dlq is defined in the queuemanager)
5. use the dead letter queue handler to change the destination, e.g.
DESTQ(wrongqueue1) ACTION(FWD) FWDQUEUE(correctqueue1)
Check the system administration guide for the rule table syntax of the dlq handler.
MO71 supportpac does have a move / copy function but i am not sure whether it can be of help because afaik it woll not change the mit header. you may verify that yourself

Mr Butcher,
Wow - I like that solution, there's nothing like a bit of lateral thinking..
And this would work in terms of redirecting specific messages also..
Now, I'd better go and remind myself how the DLQ handler works again!
cheers

sorry for asking the obvious, but did you rtfm? especially the mqsc command reference? 
anyway, there is a move command.ö you can also use MO781 supportpac, which helps you to move or copy messages, even between queuemanagers

Or # 5 could be:
5. Use MQ Visual Edit's 'forward' function and check the 'Remove DLH' checkbox.

Have you used the search button (upper right hand corner). There are a couple of SupportPacs that can do that along with Capitalware's MQ Visual Edit tool.
