In any deployed configuration of Component Servers, one or more Servers act as router and distributes requests to Servers on a round-robin basis. You specify whether a Server is a router when you launch the Server processes (see Configuring, Starting, and Stopping the Server Executable).
Each client must specify a router as well. You do this with the API ostc::addRouter(). On Windows platforms, you can use the executable ostcSetRouter.exe instead of this API.
ostc::addRouter()
static ostc_Session* addRouter(char *host_and_port);
host:port
