Activating OLD used password for FND User oracle apps

Oracle Applications by default restrict you to reset the old earlier used password. The reason being all OLD passwords are stored in FND_USER_PREFERENCES table. We can use the following queries to see all the entries (though all passwords will be in encrypted format)

select *
from applsys.fnd_user_preferences
where user_name = 'SYSADMIN'
and module_name = 'PWDVALREUSE'

In order to reset/reuse the earlier USED password, one can delete all the entries from above mentioned table

DELETE
from applsys.fnd_user_preferences
where user_name = 'SYSADMIN'
and module_name = 'PWDVALREUSE';

COMMIT;
