The channel and qmgr have a max of 100MB. So what ever is beyond 100MB YOU need to segment programatically...

From the App Prog Ref, I understand that with MQMF_SEGMENTATION_ALLOWED flag set, the longest message that can be sent is 999 999 999 bytes. And I guess MQMF_SEGMENTATION_ALLOWED means that the queue manager is segmenting the message, as requested by the application.

If the destination is a local queue or resolves to a local queue, the upper limit depends on whether:
The local queue manager supports segmentation.
The sending application specifies the flag that allows the queue manager to segment the message. This flag is MQMF_SEGMENTATION_ALLOWED, and can be specified either in a version-2 MQMD, or in an MQMDE used with a version-1 MQMD.
If both of these conditions are satisfied, BufferLength cannot exceed 999 999 999 minus the value of the Offset field in MQMD. The longest logical message that can be put is therefore 999 999 999 bytes (when Offset is zero). However, resource constraints imposed by the operating system or environment in which the application is running might result in a lower limit.
If one or both of the above conditions is not satisfied, BufferLength cannot exceed the smaller of the queue's MaxMsgLength attribute and queue-manager's MaxMsgLength attribute. |
Please correct me if my understanding is wrong. |

Sure but you're not connected in bindings mode now are you?
So 100 MB is the upper limit for your client channel and that is what your limit is...
Enjoy

| Thanks everyone. I will try out application segmentation. |
