Changing Oracle Application Users Password

At my client site, we needed to change password of all testers, functional and technical folks. Although we used Oracle application System Administrator responsibility and changed each users password, i think this script could have worked well

--set serveroutput on size 100000 DECLARE i number; TYPE t_tbl is TABLE of varchar2(80) ; l_users t_tbl := t_tbl('GX3ABC', 'X0ABCD'); BEGIN FOR i in l_users.FIRST..l_users.LAST LOOP dbms_output.put_line('changing Password for user: ' || l_users(i)); fnd_user_pkg.updateuser ( x_user_name => l_users(i) , x_owner => 'USER-ABC' -- This should be user-id of person who is running the script , x_unencrypted_password => 'Welocme2LaLaLand', , x_password_date => SYSDATE - 1 ) ; END LOOP; commit; END;
