sqlplus: fresh installation: can't connect

Hello all,

It has been a while since I installed Oracle Database from scratch. I remember that with older versions you could simply login with username scott and pasword tiger. I have just installed Oracle and cannot connect. Should I create a user called johndoe and connect as johndoe? How should I accomplish this?

Thanks,

Neil
