The Server Option for CICS provides a new modifiable exit routine, SYGWMAP, for dynamically changing the name of the default remote procedure called in response to a client language request. The Server Option context handler then uses functionality coded in the SYGWMAP exit to map a language request to a CICS transaction.
The SYGWMAP exit can be used only for language requests in a two-tier environment. The Server Option context handler does not use SYGWMAP for requests that contain a remote procedure call, for example:
EXEC remote_procedure
where remote_procedure is the name of a remote procedure.
