Hello guys, for the past 6hours I've been trying to create new local host connection in SQL developer, so I could study and do homework...
So as of now I am able to create a connection if I choose SID to be "xe", but if I change it to "orcl" i get this error:ORA-12505, TNS:listener does not currently know of SID given in the connect descriptor
I've been trying to find a solution for a long time, but there is just 0 info on the web.. SO how do I add "orcl" in listener.ora or whatever place i should add it? Please help me, thanks
