All,

Could anyone guide/show me some sample exit code? Perferably assember or Cobol. C/C++ will work also, just don't have the MVS C compiler ready to go yet.


I am wanting to have an auto-defined cluster sender channel bind to a specific VIPA address. According to this IBM doc locladdr doesn't work..of course I tried to trick it and add it to the SYSTEM.DEF.CLUSSDR but couldn't fool it.

IBM Doc: http://www-1.ibm.com/support/docview.wss?rs=0&q1=IY49334&uid=swg1IY49334&loc=en_GB&cs=utf-8&lang=


Thanks....

Offshore, what is it that you wanted to do really?

The sample exit code, I believe can be found in the App Prog Guide, and also at the sampmq site.

I think you will have to write a channel auto definition exit (CHAD), to do the trick.

MQ will allow you to specify the exit value... but it will get it from the CLUSRCVR you're talking to..... so the real way is CHAD exit.

You can use BlockIP as inspiration, it's writeen in ASM, and is the only z/OS exit I'm aware of writeen in ASM.
http://www.mrmq.dk/BlockIP.htm#BlockIP%20security%20exit

Maybe it's time to write a CHAD exit, but its' quite hard to cover any requirement... It's needed when dealing with security exits on the full repos qmgr. in a mixed environment with Z/OS and distributed MQ.

Just my $0.02
