Restricting third party tools to connect to oracle

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.
thankyou,

Hi kishore alapati!
I guess your problem is the following line:
<pre>
IF v_prog LIKE '%TOAD%' OR v_prog LIKE '%T.O.A.D%' OR v_prog='TOAD.exe'
</pre>
Maybe you don't catch all the strings from a toad-connection. Rewrite your trigger so that it stores v_prog for each connection in a table. Evaluate the stored values and replenish your If-clause with the new found values.
Hope that helps!
yours sincerely
