SQL*Plus - Create New User and Login

This section describes how to use SQL*Plus to create a new user in Oracle server and login as the new user.

In order to login to Oracle Oracle 11.2 server, without using the Windows user group authentication, I need to add a new user and resolve the "ORA-12154: TNS: could not resolve the connect identifier specified" error.

1. Log in as admin with Windows user authentication and create user "Herong".

herong> sqlplus /nolog

SQL> -- Using Windows user group authentication for now
SQL> CONNECT / AS SYSDBA
Connected.

SQL> -- Create a new user Herong
SQL> CREATE USER Herong IDENTIFIED BY TopSecret ACCOUNT UNLOCK;
CREATE USER Herong IDENTIFIED BY TopSecret ACCOUNT UNLOCK
            *
ERROR at line 1:
ORA-65096: invalid common user or role name

SQL> -- The above error is caused by the Multitenant Environment feature 
SQL> -- introduced in Oracle 12. It requires the user name in the CDB 
SQL> -- CDB (Container Database) being prefixed by "C##...".
SQL> -- But you can turn that requirement off by:
SQL> alter session set "_ORACLE_SCRIPT"=true;

SQL> -- Create a new user Herong
SQL> CREATE USER Herong IDENTIFIED BY TopSecret ACCOUNT UNLOCK;
User created.

SQL> -- Give login permission to Herong
SQL> GRANT CREATE SESSION TO Herong;
Grant succeeded.

SQL> exit
Disconnected from Oracle Database 11g Express Edition ...

2. Log in as Oracle XE user "Herong".

herong> sqlplus /nolog

SQL> -- Try with a wrong password
SQL> CONNECT Herong/WrongPass
ERROR:
ORA-01017: invalid username/password; logon denied

SQL> -- Connect with the correct password
SQL> CONNECT Herong/TopSecret
Connected.
SQL>

SQL> SELECT username, privilege FROM USER_SYS_PRIVS;

USERNAME                       PRIVILEGE
------------------------------ ----------------------
HERONG                         CREATE SESSION

Okay. I have a new user created in Oracle XE server. I can login as the new user with SQL*Plus.
