| Hi, We have large number of applications connecting to same queue manager using their own server connection channel. Is it possible to stop server connection channel manually if we don't want the application to send the message. |

Look in the appropriate KC - see if there is a STOP command for channels, and if so, to which channels it is applicable.

Warning - recently we did this, and by doing it, we have seen side effects.
If your application continuously tries to make a connection attempt to the queue manager in an infinite loop without a delay or stopping after an exception, you are probably saturating the listener port which may stop responding to future connection requests!

| I executed runmqsc command to stop the Server Connection Channel, but it is showing the status "STOPPING" for long time. I am not sure whether client Application is still trying to connect it and may be that's the reason it is not stopping. Also, I am seeing some messages are lying on dead letter queue. What could be the reason. Should the Server connection stop if no application is using it and it is "idle" state. |

What's the sub status? Did you use force?

Could be. What does the documentation on the stop command have to say on this matter?

The reason could well be the one coded in the messages.

Probably. What does the documentation say?
