not at all. we have clients installed on the local intranet from where we
are trying to connect even on the server itself where the database is
residing, from there we cant connect to SQL using
user/pass@(protected) after setting oracle sid using SET
ORACLE_SID=SID and then sqlplus
user/pass we are able to connect but not using the connect string.
Dont know why ???????????
