When oracle is installed it creates a number user almost 20.
At the time of installation except the DBA accounts all others are LOCKED by default.
Which can be unlocked at the time of installation orlater on by logging in through the DBA accounts.

but i am new to this ....
so have no clue on how to login as admisn console ?
how to do tht ... can ya elaborate it ..
thanks for the help
Have you created a database? If so you would have specified the SYS and SYSTEM passwords. If you haven't done this bit then run the Database Configuration Assistant to help you create a database. If you have created a database and you are using sqlplus you may have to configure your tnsnames.ora file using the net configuration assistant.
