System programming for transaction routing

You have to perform the following operations to implement transaction routing in your installation.

1. Install MRO or ISC support, or both. This is described in Configuring CICS interconnectivity.
2. Define MRO or ISC links between the systems that are to be connected, as described in How to define connections to remote systems.
3. Define the terminals and transactions that will participate in transaction routing, as described in Defining remote resources.
4. Ensure that the local communication profiles, transactions, and programs required for transaction routing are defined and installed on the local system, as described in Defining local resources.
5. If you want to use dynamic transaction routing, customize the supplied dynamic routing program, DFHDYP, or write your own version.
   For programming information about how to do this, see Writing a dynamic routing program.
6. If you want to route to shippable terminals from regions where those terminals might be 'not known', code and enable the global user exits XICTENF and XALTENF.
   For programming information about coding these exits, see ‘Terminal not known’ condition exits XALTENF and XICTENF.
