I just installed Oracle 9i Developer suite and Personal edition on my home computer. I tried to run a form using Form Builder, but a log on window appears and asks for the user name and password. I entered it in, but it doesn't perform like it should be. The message was ORA-12560, i think. I read the error message, but don't understand what to do. It's something about TSN:Protocol adapter. My computer connects to the Internet via a router. The ip it suggests was 127.0.0.1.
Please advise. Thanks.
