The DSRTPGM system initialization parameter specifies the name of a distributed routing program. The distributed routing program must be specified in the routing region and each target CICS® region.
For information about which BTS processes and activities are eligible for dynamic routing, see Administering BTS.
For information about which non-terminal-related START requests are eligible for dynamic routing, see Routing transactions invoked by START commands.
For eligible non-terminal-related START requests, the CICS sample distributed routing program, DFHDSRP, is invoked.
