I just downloaded and installed Oracle 19, with the default settings for installing on a PC (non-server,) and SQL Developer. SQL Developer detects two Oracle connections, called
ORCL, but I'm not able to connect to either one of them. It keeps saying I have the wrong username or password.
I picked a memorable password that I'm certain I'm not getting wrong, so I can only imagine the problem is with my username. SQL Developer is supplying the names of the connections as the username. That doesn't work. A bit of Googling suggests using "SYSDBA" as the default username. That doesn't work either. So... what exactly will work? What do I have to do to connect to this database?
