Hi All,
I found my Listener is down suddenly, the reason is not known. When I started the Listener it is up now. Could any one tell me in what circumstances the Listener goes down. Also tell me to understand this problem which MQ log I need to see, tell me the name of the log file with path. This is urgent as I need to inform this to my user.
With Thanks,
Vasu. |

I assume you are talking NT/Windows 2000. Normally the listener is pretty robust, and stays up whatever happens (including when a queue manager it is associated with it has ended or crashed).
As always, have you looked in the error logs? Also look in the @SYSTEM/errors log, this is a good one for invalid queue manager connections. |

Hi dgolding,
Thanks for the reply.
The environment is Unix not NT. I hope you were mentioning the log file which is in the below path.
/opt/mqm/qmgrs/@SYSTEM/errors/AMQERR01.LOG
I also have the log created in the following path.
1. /var/mqm/errors/
2. /var/mqm/qmgrs/<QueueManagerName>/errors/
In what circumstances, I should see which log. Can you please help me on this.
Thanks,
Vasu. |

Normally you should look at both of them. But I would go to
/var/mqm/errors/ first and look if any FDC's are cut. Pick the latest FDC and see if it can provide you any information.
If you can post your FDC then may be we can help you figure what went wrong. Also provide details like
1. MQ Version and CSD maintenance level
2. Platform
etc.

I assumed it was NT/2000 because normally you don't use "runmqlsr" on Unix - inetd does it all for you. Where you running the "runmqlsr" process direct? Could somebody have killed it? I don't suppose you had output redirected to a file 
Possible causes of runmqlsr dying:
- corruption of MQ IPC resources
- being killed, or somebody doing an "endmqlsr"
- /var/mqm being unmounted, maybe....
