Hi friends,

In our project, we are using degault queue max. length(ie 4 MB). But rarely we are getting messages more than 4 MB. In such cases message is getting failed. So we planned either to increase queue's max message length or implement segmentation. Can anybody suggest which is better option with less changes.

Before any IBMer's get in

BROKER 6.0 goes out of support in less than a month.

Back to your topic.

You seem to be saying that changing the qmgr & queue maxmsglen is going to be a significant task and you are asking about message segmentation etc.

Everthing other than issuing a few runmqsc commands is going to be significantly harder.

How difficult is this?

Code:

alter qmgr maxmsglen(1048576000)
alter ql(<insert name here> maxmsglen(1048576000)
repeat above as required.

Your flows must be pretty small IMHO. It is normal practice to increace the maxmsglen on all SYSTEM.BROKER.* queue just to allow deployments to take place.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.
