Hi all,

I'm facing a little problem:

Sending messages from QM1 to QM2, MQPUT of QM1 asks for COA/COD reports (that assures the receiving/processing of the message). BUT, if the sender channel from QM2 to QM1 (QM2 is out-of-the-company) is not running, how can I guarantee that the message was receipt/processed?

There is another way to get a confirmation, for instance, by the MCAs?

tks,

Hi,

Sending channel end knows that a message has been successfully sent (unless it is a nonpersistent message and the channel has NPMSPEED set to FAST), but it cannot know whether the mesasge got to the proper queue (it may have gone to DLQ or been sent to another queue manager). So the only mean of getting such information are the MQSeries provided reports.

Hi Marcin. Thanks for your reply.

In my case, doesn't really matter if the message got to the proper queue, DLQ or another QM, so it could help.
I had some teory about that, but no idea how to do. Maybe coding a channel exit. Have you/someone ever seen anything?

tks

Hi,

A channel exit won't be helpful, because at the sending side exits are called after a message is got from xmitq but before it is sent.
So when the exit finishes, you don't know if the message was sent succesfully or not.

A hint:
If you set BATCHSZ to 1 for your channel, you will know that a message has been succesfully sent when the next message is consumed from the xmitq!

I'll try this. Thanks for a while.
