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.

C:\herong>cd \local\orablexe\app\oracle\product\11.2.0\server\bin\
C:\...>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;
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 ...

C:\...>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 11.2 server. I can login as the new user with SQL*Plus.
