We have 2 queue managers...QM1(Mainframe) and QM2(Nonstop). The sender and receiver channels have been set up between two queue managers. Sender channel will start automatically whenever messages arrive on the corresponding transmission queue.
We stopped the application on QM1 after it puts 10 message on a remote queue. 10 messages went successfully on the remote queue manager's local queue but we can't see any reply message in the reply queue on QM1. Instead we can see that the 10 messages are still on the local queue on QM2.
Is this because the application is stopped at QM1 or there is some another reason? Could you please give me your suggestion on this? |

| What piece of all of this is responsible for creating and sending the reply messages? |

To be very honest I really don't know whether the app at QM2 is running or not. But as per my knowledge it should be stopped otherwise it would process these messages and send a reply.
I just want to know is there exist any other issue behind this scenario? |

The only scenario you've presented is "an application didn't send a message".
The only thing that's supposed to send reply messages is AN APPLICATION.
It's not clear what you're trying to find out, or trying to measure.
If you want to test the route of messages across a queue manager network, you should use the trace routing functions in MQ.
If you merely want to understand if you've created a working MQ network - messages moved from one queue manager to another. Good job! It works! (which one is the icon for exactly no sarcasm at all?) |

Maybe the app is not running.
Maybe the app is running but hung.
Maybe the app is running but not authorized to get messages from that particular queue.
Maybe the app is running but doing selective MQGETs, your 10 messages don't meet its criteria.
Maybe the app is running and stuck in a poison message loop on the 1st message, picking it up and backing it out over and over and over and over and over.......
