User Role Privilege: Unlock and Change Password Made Easy

User Role Privilege: Unlock and Change Password Made Easy

In an Oracle database, users are granted privileges that enable them to perform specific actions such as accessing tables or executing stored procedures. SQL queries can be used to retrieve information about the privileges granted to a user in the database.

The dba_TAB_privs view contains information about object grants to all users in the database. To retrieve the privileges that a user has on tables in the database, the following SQL query can be used:

SELECT privilege, TABLE_NAME FROM dba_TAB_privs WHERE grantee='username';

Similarly, the DBA_ROLE_PRIVS view displays all roles that are granted to all users and roles in the database. To retrieve all the roles that have been granted to a user, the following SQL query can be used:

SELECT * FROM DBA_ROLE_PRIVS WHERE grantee = 'username';

To retrieve all system privileges that have been granted to a user, the DBA_SYS_PRIVS view can be used. The following SQL query can be used for this purpose:

SELECT * FROM DBA_SYS_PRIVS WHERE grantee = 'username';

The dba_users view contains information about all users in the database. To retrieve the username, password, account status, lock date, and expiry date for a user, the following SQL query can be used:

SELECT USERNAME, PASSWORD, ACCOUNT_STATUS, LOCK_DATE, EXPIRY_DATE FROM dba_users WHERE username='username';

To retrieve information about password resources for the 'DEFAULT' profile in an Oracle database, the dba_profiles view can be used. The following SQL query can be used to retrieve all password resource records for the 'DEFAULT' profile:

SELECT * FROM dba_profiles WHERE profile = 'DEFAULT' AND resource_type = 'PASSWORD';

To unlock a user account in an Oracle database, the following SQL command can be used:

ALTER USER username IDENTIFIED BY password ACCOUNT UNLOCK;

The ALTER USER command is used to modify the settings of a user account in the Oracle database. The IDENTIFIED BY clause sets the password for the user account. The ACCOUNT UNLOCK clause unlocks the user account, allowing the user to log in. It is important to note that running this command requires DBA privileges.

In addition to unlocking a user account, it is also possible to change the password for a user account using the ALTER USER command. The following SQL command can be used to change the password for a user account:

ALTER USER username IDENTIFIED BY new_password;

In this command, new_password should be replaced with the new password for the user account. It is important to note that running this command also requires DBA privileges.
