Using MQ 5.2 the default max message size on most queues is the product max of 100MB. This there a good reason that the channels are still set to the old max of 4MB.
Is it realistic that messages used to control MQSI Broker deploys from the Config manager could exceed the 4MB limit?
I realize these appear to be unrelated but we have a condition that ties them together.
Thanks.

FYI: Max messages per que in version 5.2+ is 640,000 messages or 2GB data, which ever you hit first according to IBM.

Well if you set them to 100mb, when the channel starts up it creates
a buffer (based on max message size) to hold messages, if you set every channel to 100mb it will allocate 100mb buffer for every channel. IF you have 10 or 15 channels
do the math. You would need a whole lot of ram. The queue definition doesnt allocate ram based on max message size

| Is this 2Gb limit per queue documented anywhere? It may explain a strange problem I was having about a year ago.... |
