FND tables for login details

How to find user logged in Oracle Applications and and I would like restrict some user login during weekends to oracle applications.

 How Logged to Forms

select distinct fu.user_name User_Name,fr.RESPONSIBILITY_KEY Responsibility from fnd_user fu,
fnd_responsibility fr, icx_sessions ic
where fu.user_id = ic.user_id AND
fr.responsibility_id = ic.responsibility_id AND
ic.disabled_flag=’N’ AND
ic.responsibility_id is not null AND
ic.last_connect like sysdate;

There are three primary tables which are involved in using the system profile ‘Sign-On:Audit Level’:

1) FND_LOGINS
2) FND_LOGIN_RESPONSIBILITIES
3) FND_LOGIN_RESP_FORMS

- When the profile is set to “User”, the only table that gets updated is the table FND_LOGINS and only one record per user session

- When the profile is set to “Responsibility”, both FND_LOGINS and FND_LOGIN_RESPONSIBILITIES will be updated:
a) FND_LOGINS gets only one record per user session
b) FND_LOGIN_RESPONSIBILITIES will be updated with one record for each responsibility selected during the session

- When the profile is set to “Form” all three tables are involved:
a) FND_LOGINS gets only one record per user session
b) FND_LOGIN_RESPONSIBILITIES will be updated with one record for each responsibility selected during the session
c) FND_LOGIN_RESP_FORMS will be updated with one record for each form selected during the session
In terms of performance, the data capture has negligible overhead.
