Hi,

I'm having some serious disk space problems when doing MQSeries JMS publish/subscribe's. All the messages that I publish are appended to some file - C:Program FilesMQSeriesqmgrs[queue manager name]Queues[directory name]Q. Examples of "directory name"s are !!GHOST!56636A8D!0!D4FF0961!2 and !!GHOST!56636A8D!0!116C6875!2. Since my messages are fairly large, this behavior is causing my server to run out of space very quickly (within a day).

Since my messages do not need to be persisted (only subscribers that are running at the time of publish need to receive the messages), I was wondering if there is any way to turn this *feature* off??

Please note that since I'm using JMS, I do not specify the queues to use for publish/subscribe. Instead, the system queues created by running MQJMS_PSQ.mqsc are used. I was thinking maybe I can change the DEFPSIST or DEFTYPE parameters of these system queues, but I'm not sure which one to change or what effects it'll have.

If anyone can tell me how to avoid this disk space problem, it'll be greatly appreciated. Thanks in advance for your help.
