I'm trying to build a .NET app to send messages to a MQServer. The messages will habitually be well over 40 megabytes in size, but even when I set the Qmanager, channel and queue max message size to 100 megs I still get a 2010 Data Length Error upon putting the message.
A two-year old post here indicated that there might be a limitation to 4 megs from clients if one was using the environment variable MQSERVER="<something>" on the client, but I am specifying the MQ server in the q manager as:
MQQueueManager qm = new MQQueueManager("TQM", "OFM.TQM.AGR.SVRCONN", "000.000.00.00(1414)");
Any ideas?

Looks like you need to use a channel table.

Sorry, but I'm not sure if this addresses the problem.
Here's some logging messages from the app:

Started
The queue's name is: AMQ.4768296902BE0220
Maximum message size on queue is 4194304 bytes |
**but when you look at the property on the queue itself it says 51200000.

| Maximum message size on qmgr is 4194304 bytes |
** same as previous
| Quote: |
Finished queue initiation in 0 seconds
Read message from file in 4 seconds
Wrote string to message in 16 seconds
MQ Operation 'put' failed with: CompCode: 2, Reason: 2010 |

What version of MQ Client are you using? One of the older ones had a bug where .NET apps were limited to 4MB. But I think that was back at MQ 5.3.0.*. I hope you are using MQ 6.0.2.*.

| You need to ensure the max message len is set everywhere; ClntConn, ServConn, DLQ, Queue, Queue manager, Xmit (if remote) etc |

Looks like a dynamic queue to me. Check max msg length on the QModel definition, too. As shipped from the factory, max msg length on midrange MQ is 4meg. |
