Hi,

I am trying to run the listener from the command prompt.
Environment: windows 2000
MQ 5.3
i issue the MQSC command 'start listener' it gives me message saying

AMQ8021: Websphere MQ listener program started.

but when i go to MQ Services window the listener is not running.error log gives following message

AMQ9255: Listener already running.

EXPLANATION:
The request to start the WebSphere MQ listener failed because there is already
a listener running against the specified network resources.

i have tried changing the port number and issued the command but there's no change. please let me know where i am making the mistake.

From runmqsc, "start listener" can only start listener on the default port or 1414. It sounds like you already have a listener that is defined as a service so that it starts when the queue manager starts.

Starting it as a service is a good way to do it. If for some reason you do not want the listerner to start with the queue manager, go to MQ Services and undefine the listener. Then you can start it manually as needed from runmqsc.

If you just need to start a listener on a different port and it doesn't matter if it dies when you logoff, go to a command prompt and enter "runmqlsr -t tcp -m QMGRNAME -p PORT#

Actually i have created the listener using the following command in the script
amqmdain crtlsr QMGR -t tcp -p portnum
when i run the script the listener is created but not started. so how do i undeefine the listener so that i can start it using scripts.

Thanks

amqdain doesn't give the granularity you need to set AUTO|MANUAL for individual services. You can only do it at the queue manager level. You will have to open the WebSphere MQ Services GUI and modify the listerner. You can set it to autostart. Then it will start when the queue manager starts. Also, you can undefine it from this GUI as well. From amqmdain, you can set the queue manager and all services to autostart with "amqmdain QMGR auto".
