Oracle changes user password

If you are a database administrator or a user who has forgotten your password, here are some steps to help you change your Oracle user password.

1. Connect to Oracle database

Enter the command line and enter the SQLPLUS command, as shown below:

sqlplus sys as sysdba

In You need to enter the administrator account and password when logging in.

2. Switch to the user who needs to change the password

Enter the following command in SQLPLUS to switch to the user who needs to change the password:

ALTER USER user_name ACCOUNT UNLOCK;

In the above command, "user_name" is the user name whose password needs to be changed.

3. Change user password

Enter the following SQL statement to change user password:

ALTER USER user_name IDENTIFIED BY new_password;

Similarly, "user_name" is the username whose password needs to be changed, and "new_password" is the new password that will be used as the user's login information.

4. Exit SQLPLUS

After changing the password, use the EXIT command to exit SQLPLUS and disconnect from the database.

5. Verify new password

Reconnect to the Oracle database and verify using the new password to ensure the change is successful.
