Blocking toad

Question

hi,
my production database is a 2 node rac(9.2.0.6). i have written a trigger to block toad from connecting to database .the trigger is given below.
CREATE OR REPLACE TRIGGER block_tools_from_prod
AFTER LOGON ON DATABASE
DECLARE
v_prog gv$session.program%TYPE;
BEGIN
SELECT program INTO v_prog
FROM gv$session
WHERE audsid = USERENV('SESSIONID')
AND audsid != 0 -- Don't Check SYS Connections
AND rownum = 1; -- Parallel processes will have the same AUDSID's
IF v_prog LIKE '%TOAD%' OR v_prog LIKE '%T.O.A.D%' OR v_prog='TOAD.exe'
THEN
RAISE_APPLICATION_ERROR(-20000, 'Development tools are not allowed on PROD DB!');
END IF;
END;
my toad version is 8.0.0.47.some users are able to connect to toad.some are getting restricted.how to restrict all users to connect to toad.

SELECT program INTO v_progTry including the column Module in this query as NVL (Program, Module).
Also, compare the executable names in a common case. It may not necessarily be in the same case as you expect it to be.
IF UPPER (v_prog) LIKE '%TOAD%' OR v_prog LIKE '%T.O.A.D%' OR v_prog='TOAD.exe'On a side note, if any of the users are connecting as SYS user (may be they know the password), this trigger will not prevent those logons. You will just get an entry in alert.log with raised exception.
AND audsid != 0 -- Don't Check SYS ConnectionsI did not understand the comment in this line.
