create user scott identified by tiger ;

to do that you need to log in first and normal users can't create another user .

This error

ERROR: ORA-12154: TNS:could not resolve service name

only appears when you don't have an instance of a database or you don't have the listener on.

Make sure you have the DB online and the listener.

You can view the listener status with: 'lsnrctl status' and start it with 'lsnrctl start'.

When the listener is running, you can enter as sysdba (defined when the DB is installed) and type an 'startup' command to start the database you have define. Use 'startup db_sid' if you have more than one.

Hope it helped.

Er guys, SqlPlus 3.3.4.0.0? Isn't this from the days of Oracle 7?

I would think we would need to know more about your config before we could really help!

client / server, versions of oracle and client, where components are installed etc.

Your error suggests that the oracle client components are not installed / not in the path / wrong oracle_home selected - to name but a few possibilities!
