ORA-12203: TNS:unable to connect to destination

appsfhApr 10 2013 — edited Apr 10 2013
Hi Guyz,

I have a connection problem with the Developer Suite and the Database. When I'm trying to connect I'm facing 'ORA-12203: TNS:unable to connect to destination' Error in the Server (I can connect with sqlplus). But the clients/users can connect to the application (Developer Suite to the Database).

Please find my related details,
Database - 9i R2 EE
Developer Suite - 6i R2
OS - Windows Server 2003 EE
Database ---
