Hello good ppl.
I have some application which should work in asynchronous method.
Scenario: I'm sending some XML file as a message to queue, get ack* from MQSeries, and show the acknowledge in some message box for user, to be sure the message recieved in the queue.
1. Can i do that not in programmaticly way?
2. If not - what methods i should use in my application?
thank you.  |

You don't get an acknowledgement/ack.
You get a return code, or in the case of the object-oriented languages then no exception has been thrown.
This is strictly for "MQ has accepted the message for eventual delivery", not "the message has been delivered" or "the receiver has read the message". For those, you can ask for a Confirm On Arrival or Confirm On Delivery report - and I forget which one is which.

As jefflowrey has said, you'll get a completion code and a reason code. If the completion code indicates failure, the reason code will tell you why.
Typically if the message is sucessfully put, it's taken that it will reach it's destinaction. This is the essence of the assured delivery WMQ offers.

And, again, if you're using an object oriented API (java, .net) you might not get a reason or completion code from the PUT. You'll just fail to get an exception - so only write NEGATIVE if you get an exception.

I had assumed that COA is report that the message is delivered on the local queue and COD is the report that the message reached the remote Local queue.
Is my assumption correct

I think that COA means that the msg has reached its (final) destination queue, and COD means that the msg has been read from the queue. Look it up, it is probably in the APR.

No.
If you do a forum search, this has been a popular topic of late. With many of the topics containing rants from me on why they shouldn't be used. You'll also find both message types described in the documentation.
