I have setted my database environment following way for IIOP protocol connection but still not getting it. Please guide me in this.
Please also tell me how to test whether connection is proper.

mts_max_dispatchers=10
mts_servers=1
mts_max_servers=10
mts_listener_address="(ADDRESS=(PROTOCOL=tcp)(host=PC_MY_NT)(port=2481))"
mts_service = ORCL
