| Several ways....the easiest is probably to use MirrorQ (I think that costs money though), or you could roll your own code to do it....The important questions are why do you want to do it and on what platforms. |

Well if you are learning MQ and this is your assignment I am guessing they want you to write your own code. Look in the APG for Browsing messages (using a non-destructive get). Probably wouldn't harm to look up MQGET with a wait unlimited either 
MirrorQ is a product that you can purchase that I think will do what your assignment is, but like I say I doubt whoever set your assignment is going to accept it as the solution. |

I thought it was freely available.

MiirorQ would be useful if you want the messages to be copied to a second queue in "real time".
If you have messages on a queue, and you just want to replicate them to another queue, then the q Support Pac (MA01 ??) will do just that.
Cheers,

Do you have a queue already populated with messages that need to be copied? Or can this mirroring system be "switched on" one day, whereupon only NEW messages being put to the first queue will be copied to the second queue?
If the latter, then API-crossing exits can do what you want. Search the docs for this term.
If the former, then you'll need to browse the first queue, and for each message make a copy onto the second queue. I dislike this option because it's a one-off job that you can't repeat reliably in the case where there are putters and getters live and working on either queue.
As always, the option chosen must fulfill all the requirements that you have been given. The above are only ideas (patterns?) of course, and certainly won't meet your full requirements.
Is this really a college / university exercise? This is what others might read into the word "assignment"... |

hi mvic,
i already have a queue and it is populated.
only thing i have to do is to get both the source and destination from the user and to copy the messages in the source queue to destination queue.
i understood the concept and i've started doing it.
thanx,
rvikky |
