I found where the maxmessage size defaults to 100 MB

http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/index.jsp?topic=/com.ibm.mq.csqzal.doc/fg10560_.htm

Code:
On WebSphere MQ for AIX®, WebSphere MQ for i5/OS®, WebSphere MQ for HP-UX, WebSphere MQ for Linux, WebSphere MQ for Solaris, and WebSphere MQ for Windows, the MaxMsgLength defaults to 100 MB (104 857 600 bytes).


But what I can not find is the maximum message size (not just a default) for Solaris in v7

Any ideas ?

No version of MQ on any platform supports a MAXMSGLN value larger than 104857600 as of this date.

That has nothing to do with how large a "message" can be - at least a logical message. (anticipating bruce's follow up comments to come about grouping, segmentation, and logical vs. physical messages).

How big are the messages you need to put into MQ?

Maximum message length is 100MB on v7 on all platforms. This is the maximum size of a physical message.

An application program can construct a logical message much grater than 100MB. Refer to the WMQ Application Programming Guide, and WMQ Application Programming Reference.

As mvic asked, how big are the messages you need to put into MQ?
