Keeping it short, we made some client connection changes on our MQ server and then provided a new AMQCLCHL.TAB file for an MQ client running on an AIX box. We are now getting rc=2059 so I'm guessing there is an issue with the TAB file. I've asked the server admin to get me the log file out of /var/mqm/errors, but he says and I've confirmed from a second admin that the AMQERR01.LOG file is not there. Is there a way to turn off logging? I'm trying to figure out why this file is not there.

Thanks for your help!

No, I don't have the qmgrs diretory on any of the clients I have installed. I would assume it would only get created when you define a queue manager on the client???

I don't think there is an AMQERRxx.LOG on the client side, only on the server side...

AFAIK the logging is built from the actions of the queue manager, so only exists on the server side.

There should be AMQERRxx.LOG on the client side. Is the /var/mqm/errors folder empty?

EDIT for Vitor:

I remain unconvinced about client side logging.

Client side logging exists.

Not all errors that a client experiences will get logged to the client side error log.

Not all the errors that get logged to the client side will be meaningful in troubleshooting. For example, the client side may just log a failed connection, where the server side would log that the channel doesn't exist. That kind of thing.

Yes, that's exactly what I'm looking for. I'd like to know if there is a failed connection causing this system, which is connecting to the queues, to fail. I've had this happen in the past when an MQ server was switched out and I provided a new TAB file for the clients. We were able to see what was failing in the error log file on the client. That was also an AIX server. The TAB file I provided looks correct to me. There isn't anything being logged on the MQ server, so the client isn't connecting at all.

Any more ideas??? I'll try some other avenues for the time being.

Thanks for the comments so far.
