I am using MQ5.3 on AIX. As per my understanding, the actual messages in queue are stored under
[b] /var/mqm/qmgrs/<QM_NAME>/queues/<Q_NAME> [/b]
and the file name is q.
My question is when I do MQGET for all the messages, why my data file size is still same as before? Doesn't it delete the messages from this file. This file size never reduces. The actual queue depth and queue data file size are not in sych. Is it supposed to be like this????
Any comments are greatly appreciated.. |

| The size of the file shrinks and grows as MQSeries sees fit. I've never seen it shrink instantly with an MQGET. I wouldn't worry about it. |

Unless they have made changes lately it will only shrink after qmgr restart.

If you want a shrink instantly you must try "Clear qlocal(name)" from the
runmqsc command line

| I think you will find queue files will only shrink when they get cleared or when they are unloaded, and that can be at restart time, or after a certain period of inactivity. Dont forget the fact they havent shrunk for an active queue isnt a problem as the space gets reused for messages, and free space kept track of. |
