Hi,

I would like to implement a Channel exit program in the mainframe side.
Please let me know if you have any detailed information on this.

1. Should we need Channel Exit program?
2. If Yes, Why do we need Channel Exit Program?
3. If you have Channel exit program in COBOL, Can you please share with me?

Please let me know.

Thanks,
Babu M

It works the other way around, friend - you tell us what you need and why, and we say "oh, what you need is a channel exit program!"

Channel exit progam is for the message security.

Like Checking whether the message is from the proper source, and encryption,etc,

Please let me know if you need any more details.

Have you looked at WebSphere MQ Extended Security Edition?

Have you looked at the MQ Information Center for how to write channel exits?

Have you looked at the SSL provisions in WebSphere MQ for what it can do for you so you don't have to write an exit?

Its all documented here:
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=/com.ibm.mq.csqzae.doc/js02458.htm

Writing channel exits is an "advanced" topic in MQ, usually done by people with a good understanding of the basic principals of MQ and intercommunication.

From manual (V5.3 on z/OS)
Code:

When writing channel exits for z/OS without CICS, the following rules apply:

Exits must be written in assembler or C; if C is used, it must conform to the C systems programming environment for system exits, described in the z/OS C/C++ Programming Guide.

Intercommunication ==> Chapter 46 ==> Wrting & compiling channel Exits ==> z/OS

Exits are C or assembler. And if you're new to MQ, don't be messing with them.
