OTMA routing of asynchronous callout requests

OTMA routing of asynchronous callout requests is required to route the ISRT alternate_pcb call to the appropriate tpipe.

Start of changeThe OTMA routing is performed by the OTMA destination descriptor or the OTMA Destination Resolution user exit (OTMAYPRX) and the OTMA User Data Formatting exit routine (DFSYDRU0). End of change

Start of changeYou can allow the exit routines to override a defined destination descriptor by setting EXIT=YES for the descriptor. Otherwise, the destination descriptor is used and the exit routines are not called.End of change

How the OTMA routing of the callout response is handled depends on your installation. The callout response can be routed back to a user or terminal or to an OTMA asynchronous hold queue.
