(Not logged on) - PL/SQL Developer ORA-28032: Your password has expired and the databaseis set to read-only OK

It seems like your database account's password has expired and the database has been set to read-only mode. To resolve this issue, you need to reset your password and then request your database administrator to grant you write access to the database.

To reset your password, you can use the ALTER USER command in PL/SQL Developer. Here's an example:

ALTER USER username IDENTIFIED BY new_password;

Replace "username" with your database username and "new_password" with the new password you want to set.

Once your password is reset, you can request your database administrator to grant you write access to the database by granting the appropriate privileges.
