Routing by user ID

Optionally, your routing program can route requests based on the CICS® user ID (userid) associated with the request. The DYRUSERID field of the communications area contains the user ID. When it is invoked for routing or because of a route-selection error, your routing program can base its routing decision on the contents of this field.

For details of how the userid is set for different types of request, see the description of the DYRUSERID field in Parameters passed to the dynamic routing program.
