Changing database password

Question

Hello friends,
In my company there are a lot of users who access an oracle database to do their daily work. Often they need to change their password. Instead of using SQL Plus, is there any way for a user to change his database password using a browser or something. ?
thanks

You don't need any internal Oracle functions. As a privileged user, create a function like:
CREATE FUNCTION expire_soon (p_days IN NUMBER DEFAULT 5)
       RETURN BOOLEAN
       AUTHID CURRENT_USER AS
   l_res NUMBER;
BEGIN
   SELECT 1 INTO l_res
   FROM user_users
   WHERE expiry_date <= sysdate + p_days;
   RETURN TRUE;
EXCEPTION
   WHEN NO_DATA_FOUND THEN
      RETURN FALSE;
END;Then, grant execute on the function to PUBLIC. You could create a public synonym for the function, or simply use owner.expire_soon when you call it.
As part of your application login procedure call the function. If it returns TRUE, then prompt the user to change their password and either do:
ALTER USER user_name IDENTIFIED BY newpassword;or create another procedure to encapsulate the command.
