Hi, I'm using Oracle Database 11g Release 2 on Windows 7 Ultimate 32 bit.
I just installed Oracle Database and I'm in SQL Developer and I'm trying to create a new connection.
When I'm in the connection window and I click on "Test" I get the message: "Status: Failure -Test failed: Listener refused the connection with the following error: ORA-12505, TNS: listener does not currently know of SID given in connect descriptor".
The SID name in the listener.ora file is correct.
I've tried stopping and starting the listener, but I got the same message.
What can I do?
thanks...
