Hi i am getting below error frequently in the logs:
9/16/2003 03:51:58
AMQ7463: The log for queue manager XPTEST03 is full.
EXPLANATION:
This message is issued when an attempt to write a log record is rejected
because the log is full. The queue manager will attempt to resolve the problem.
ACTION:
This situation may be encountered during a period of unusually high message
traffic. However, if you persistently fill the log, you may have to consider
enlarging the size of the log. You can either increase the number of log files
by changing the values in the queue manager configuration file. You will then
have to stop and restart the queue manager. Alternatively, if you need to make
the log files themselves bigger, you will have to delete and recreate the queue
manager.

AMQ7463: The log for queue manager XPTEST03 is full.
NOW IT JUST REPEATS SAYING LOG IS FULL AND STARTS BOMBING OUT WITH SAME ERRORS
------------------------------------------------------------------------------------
Now i know why this error is caused, what i would like to know is wether this error results in stopping of channels or any other effect.
Thank You |

Think through your own question and you can answer it yourself...
If you have persistent messages, inbound, that can't be logged, what will the queue manager do? If you have persistent messages, outbound, that cannot have their removal from a transmission queue logged, where will they go? If you have an application that has put so many uncommitted messages in a long-running UoW that it has filled the logs, what is the effect on other messages waiting for sending or receiving?

any additional errors or subsequent problems should be shown in the log too, e.g. transaction abend to release log space, channel stopped and so on. Whatever is currently running in your queuemanager needing log space (which is not available) may have a problem.
applications connected to the qmgr may receive proper returncodes, you will not see that in the amqerror logs.

Thanks for the replies...
After these set of errors what happens is the channel will restart automatically, i wanted to know wether the channel restart is related to the error mentioned.
Some of my queues are holding upto 5 million messages.
I am new at MQ and am trying to learn by resolving the errors.
IF there is any material available please forward me a link to the same so that i can read the background of it.
Thank You |

It's there in the Info Centre, lots of it. As a newbie you should be spending a lot of time reading, but also get your management to give you training so you have a context for which you can apply what you have read about and/or found by experimentation.

there are other situations that cause a channel to start. however, if the channel was running, and you recevie that log problem, and the channel is abending because of that and restarting, you should see something about that in the amqerr logs as these channel errors are recorded

this may not indicate a problem. it depends, how and when messages are consumed by the application, although it is not a good practise to use queues as a data store. you should investigate with your application documentation if this is "normal" or if there is the need to start (or restart) some applications to process these messages

the error logs state the same i.e. after those errors i see a restart of the channel.

My purpose stating that there are these many messages is that can 5 million messages in a queue cause the occurance of these errors ??

Are these SDR or RCVR channels, or both that are restarting? Review my comments in regard to persistent messages...

Yes, logs full rc can be directly related to insufficient logs allocated OR out of disk space.
