Writing a distributed routing program for routing BTS activities
You can use a distributed routing program to dynamically route CICS® business transaction services (BTS) processes and activities. To write your own distributed routing program, you can use the CICS-supplied default distributed routing program, DFHDSRP, as a model.
Not all activations of BTS processes and activities can be routed. To learn about what BTS processes and activities are eligible for dynamic routing, see Which BTS activities can be dynamically routed.
Restriction: The distributed routing program runs outside a unit of
work environment. Therefore, your program must not alter any recoverable resources or issue file
control or temporary storage requests.
