    You need to change your password with the following command the first time you use Oracle: 
      SQL> alter session set "_oracle_script"=true; 
  SQL> alter user user_id identified by pwpwpwpw;
    where pwpwpwpw is whatever new password you want. Note that, unlike Linux login names and passwords, Oracle account names and passwords are NOT case sensitive.
