Error message from channel control

Problems found during normal operation of the channels are reported to the system console and to the system log. In IBM MQ for Windows they are reported to the channel log. Problem diagnosis starts with the collection of all relevant information from the log, and analysis of this information to identify the problem.

However, this could be difficult in a network where the problem may arise at an intermediate system that is staging some of our messages. An error situation, such as transmission queue full, followed by the dead-letter queue filling up, would result in your channel to that site closing down.

In this example, the error message you receive in your error log will indicate a problem originating from the remote site, but may not be able to tell you any details about the error at that site.

We need to contact your counterpart at the remote site to obtain details of the problem, and to receive notification of that channel becoming available again.
