Hi,
Our /var/mqm and /var/mqm/errors is full.
Environment: WMQ 5.3.0.7, Linux 2.4.20-20.9smp
I checked the channel status and it showed the channel status as "INITIALIZING". I recycled the channel with no luck. A receiver channel is defined on the receiver side and the listener is running. The transmission queue has a curdepth of 482. My understanding is that is what is filling up the /var/mqm file system. I recycled the queue manager, started the channels and the channels were up and running but after some time had the same problem.
An FDC of 114MB was generated under /var/mqm/errors.
This is the header.

| You might want to delete (or archive) some of your errors subdirectory's contents. This might be eating up some valuable space. Also, if you are using linear logging, are you archiving the logs? Lastly, you might want to consider adding space to your filesystems. They may not be large enough for the qmgrs in your messaging environment. |

Hi Bower,
This is a test environment and We are using circular logging.
This is what our file system shows
| Code: |
df -k | grep /var
507748 481534 0 100% /var/mqm
507748 57695 423839 12% /var/mqm/log
126931 120378 0 100% /var/mqm/errors |
My understanding is the df -k option shows the space on the disk in kb, which means that we have allocated 129MB of space to /var/mqm/errors and 507MB for /var/mqm and /var/mqm/log. Please correct me if I am wrong.
My concern is, if we increase the space it might eatup the availabel space.
Any help would be appreciated. |

This is an incredibly small amout of space in this day and age of cheap storage.
We get 10+ Gigabytes of data just for /var/mqm, and make the logs as big as MQ will allow on day 1. What servers out there today can't spare a few gig? To many headaches result from file systems \ logs that are to small for MQ. And it is so easy to prevent in the first place.

I agree that it doesn't cost much to allocate more space, it's nothing I can do. That is the case with all the test systems here. We have a UNIX support team and they build the systems for us. Every time I get a new system it will be of different configuration, nothing I can do other than trying to get hold of people who can allocate more space. You know what I'm talking about.
Coming to the problem...
It was an application issue and is solved. 
Thanks. |

rm /var/mqm/errors/*.FDC should free up some space. However I would not recommend doing anything with your AMQERR0*.LOG files. I also agree with Anirud and Peter. Increasing the size of those filesystems would be a good idea.
