I've just installed oracle 8i on my computer (win 2000) and I don't know how to start. I want to create a database but I don't know which application to use and which way. I know how to do that in sql and in scema manager too, but each time I try to open those applications, username, password and service are asked from me. I've tried with system-manager but without result. I've even created some service name local for my host and listener for him but only appeared message that's not possible connection to that service. What I need to do to start work with oracle from my computer ?
