Using SQL*Plus to Unlock Accounts and Reset Passwords

Use this SQL*Plus procedure to unlock and reset user account passwords.

1. Log in as the Oracle Database software owner user.
2. Set the ORACLE_HOME and ORACLE_SID environment variables.
3. Start SQL*Plus and log in as the SYS user, connecting as SYSDBA:

            $ $ORACLE_HOME/bin/sqlplus

            SQL> CONNECT SYS as SYSDBA

            Enter password: sys_password 

    4. To unlock an account:

            ALTER USER account ACCOUNT UNLOCK;

    5. To reset the password:

            ALTER USER user_name IDENTIFIED BY new_password; 

Note:

If you unlock an account but do not reset the password, then the password remains expired. The first time someone connects as that user, they must change the user's password.
