Hi there,
I have a question about MQ.
When connecting to a queue manager i can see the queue:
SYSTEM.CLUSTER.TRANSMIT.QUEUE with a depth of 18 messages.
When I look at the q in filesystem I have the following situation:
10755 10616320 -rwxrwx--- 1 mqm mqm 10930929664 Jun 19 10:25 q
So I do not understand qhy such a huge file is exetndend in filesystem when the queue is nearly empty.
Can someone explain this behaviour ?
Best regards,
Jörg |

did you check the size of each message in cluster transmit queue
and cluster transmit plays vital role in cluster management too

Somewhere on the board is a post that covers the answer to your question, and in quite good detail. I've been looking and can't find it yet...I'll post the link if/when I do.

the transmit queue is now empty , so I can't see the size of a message. Fs queue file is still the same size |

It's a case of hitting the right keyword...which I've yet to do. Anyone out there remember the post?

Problem was solved after restarting. But I'm not understanding which process locked that amount of space... |

Thank you Peter, as usual the cavalry to the rescue. The post I was referring to was the one where someone had done quite a bit of experimentation, and documented the results...still can't find the post though, but thank you for digging out the other post.
