Title: RE: Errors trying to connect from 8.1.7 client to 7.3.2 server

What does the tnsnames.ora entry on the client machines look like? In the CONNECT_DATA entry, do you have SID=
(connect_data = (sid = AAA))
or service_name = and instance_name = ?
(connect_data = (service_name = BBB.CCC.DDD) (instance_name = BBB))
