6 minutes read

To reset the username and password for Oracle, you will need to access the database using a privileged account. Once logged in, you can run a SQL query to reset the password for a specific user. The query typically involves updating the user's password in the system table where user credentials are stored. It is important to follow security best practices and ensure that the new password meets complexity requirements. If you have forgotten the username or lost access to the privileged account, you may need to contact your database administrator or Oracle support for assistance.

How to recover a forgotten Oracle database username and password?

If you have forgotten the username and password for your Oracle database, you can try the following steps to recover them:

  1. Check any documentation or notes: Look through any documentation or notes that you may have saved when the database was set up. This may include usernames and passwords that were used during the installation process.
  2. Contact the database administrator: If you are unable to find the login credentials, contact the database administrator or the person who set up the database. They may have the information stored securely and can provide you with the necessary login details.
  3. Reset the password: If you have access to the Oracle database server, you may be able to reset the password for the username using SQL*Plus or Enterprise Manager. Connect to the database as a privileged user and run the following SQL command: 
1

ALTER USER username IDENTIFIED BY new_password;


Replace "username" with the name of the user for which you want to reset the password and "new_password" with the new password that you want to set.

  1. Use the Oracle password reset tool: If you are unable to reset the password using SQL*Plus or Enterprise Manager, Oracle provides a password reset tool that can be used to reset a forgotten password. You will need access to the Oracle database server and the SYS user credentials to use this tool.
  2. Reinstall Oracle: If all else fails and you are unable to recover the username and password, you may need to reinstall Oracle database software. Make sure to back up any important data before doing so, as reinstalling the software will result in the loss of any existing data in the database.


It is important to ensure that you securely store any login credentials to prevent this issue from happening in the future.
