Oracle/ SQL Developer connection problem.
751980Feb 6 2010 — edited Sep 26 2010I have installed Oracle 11 g and SQL Developer, When I open SQL Developer and try to make a new connection ( I name the connection, put a user name in, put my password in), I click on "Test" and I get this error:
Status: Failure - Test failed: Listener refused the connection with the followong error:ORA-12505, TNS: listener does not currently know of SID given in connect descriptor The connection descroptor used by the client was:localhost:1521:ex
Can anyone explain this to me and help me resolve this issue I am having?
