An MQChannel Exit is a program that you or some vendor writes. This program is then registered with one or more of your MQSeries Queue Managers as a channel exit.

The MQSeries queue manager will call different routines in the Exit program at different times - for instance, when a message is being passed through a channel. Which routines in the exit get called and when depends on what callbacks the exit is coded to request.

All of this is documented in the System Administrator Guide, the Intercommunication Guide, and the Application Programming Guide (different manuals have different pieces of the information, depending on what you want to do). All of these manuals are available on the IBM website, and on the documentation CD you should have received with your installation media for MQSeries.

Hi Jeff

Thank you very much. I will go through the code. A small Q will this code support all types of channel exits. Because I need it like that MQServer should reject when unknown user enters in to it.

I've got other samples here for security issues:
http://d1o111.dk.telia.net/~u149101068/tips_and_tricks.htm#LogIP%20security%20exit

These are simple but good working exits, that solve a specific task...

Just my $0.02
