Having Problem with logon & logoff Triggers for the SCHEMA

Question

hi,
I have created triggers "LOGOFF_TRIG" & "LOGON_TRIG" . This triggers fires each time the user SCOTT logings and logoff from the database and stores the info in table log_trig_table. Below the code of the trigger
LOGOFF_TRIG
CREATE OR REPLACE TRIGGER logoff_trig
BEFORE LOGOFF ON SCHEMA
BEGIN
     INSERT INTO log_trig_table(user_id, log_date, action)
     VALUES (USER, SYSDATE, ’Logging off’);
END;LOGON_TRIG
CREATE OR REPLACE TRIGGER logon_trig
AFTER LOGON ON SCHEMA
BEGIN
     INSERT INTO log_trig_table(user_id, log_date, action)
     VALUES (USER, SYSDATE, ’Logging on’);
END;But whenever i m loggin off or on using the user SCOTT there seems to be nothing being updated on table log_trig_table. Why ?

Answer 1

i tried the new code provided it is telling not sufficeint priviledge. But i have all the priviledges for user SCOTT.
Also i tried putting the commit in the below code. Tried disconnect command from theSQL* Plus. this time i didnt got any ERROR but still there were no data in table log_trig_table
CREATE OR REPLACE TRIGGER logoff_trig
   BEFORE LOGOFF
   ON SCOTT.SCHEMA
BEGIN
   INSERT INTO log_trig_table (user_id, log_date, action)
     VALUES   (USER, SYSDATE, 'Logging off');
      commit;
END;Below is what my requirement
1) Create a trigger on Schema SCOTT for logon and logoff
2) Whenever user scott is connect or disconnect the respective trigger should fire and stores the result in table log_trig_table which is in schema SCOTT
