Response measures after Oracle database password expires

When the Oracle database password expires, the user will no longer be able to access the database. In order to restore access, the following steps are required:

1. Connect to the database server

• Use a database management tool such as SQL*Plus or Oracle SQL Developer to connect to the database server.
• Enter the database name, host address, and port number.
• Enter the username and password that is allowed as SYSDBA connections.

2. Create a new password file

• Enter the following command:
  CREATE OR REPLACE PFILE='pfile_name.ora'

  <code> FROM spfile;</code>

• Replace pfile_name.ora with the file name of the new password file.

3. Edit password file

• Open pfile_name.ora using a text editor.
• Find the following line:
  #PASSWORD_GRACE_TIME=n
• Replace n with the buffering time (in days) before you want your password to expire notification.
• Add the following line to the end of the file:
  PASSWORD_FORCE_EXPIRATION=FALSE

4. Update spfile

• Enter the following command:
  ALTER SYSTEM SET spfile='pfile_name.ora' SCOPE=BOTH SID='*';
• Replace pfile_name.ora with the name of the new password file.

5. Reset password

• Enter the following command:
  ALTER USER username IDENTIFIED BY new_password;
• Replace username with the username of the expired password.
• Replace new_password with a new password.

6. Restart the database

• Enter the following command:
  STARTUP;
• This will restart the database so that the new password takes effect.

7. Connect to the database again

• Connect to the database again with a new password. You will now be able to access the database.
