Issue:
How to set up a TIML multi region routing in CICS?
Environment:
z/OS
Resolution:
See doc and comments in TIRSLEXT as follows below:
THE SYSID NAME OF THIS CICS REGION 
TO START THE SERVER IN A CICS REGION DIFFERENT FROM THE CICS  
REGION WHERE THE TISL LISTENER IS EXECUTING                
ENSURE THE COMMAREA CICS DATA AREA CONTAINS THE NAME OF THE
SYSID OF THAT CICS REGION FOR TRANSACTION ROUTING       

This is a user exit with no examples  of the possible changes.  Customer can modify as desired by specific tran code and/or userid.  Using this exit would be a static routing.  If custom processing is required, i.e., load balancing, use CICS Dynamic Routing.
