Hi, I have been trying to send message to logged on user using the database logon trigger. I can send them a message when signing them off by raising exception in the trigger but I need to send in any ugly format a message back to the sqlplus user from inside this trigger. (Not all code include for sizing) CREATE OR REPLACE TRIGGER block_tools_from_prod AFTER LOGON ON DATABASE BEGIN DBMS_OUTPUT.ENABLE(100000); SELECT program, machine, username INTO v_prog, v_mach, v_user FROM sys.v_$session WHERE audsid = USERENV('SESSIONID') AND audsid != 0 -- Don't Check SYS Connections AND rownum = 1 -- Parallel processes will have the same AUDSID's AND upper(username) in ('WORKBRAIN') ; IF UPPER(v_prog) LIKE '%TOAD%' OR UPPER(v_prog) LIKE '%T.O.A.D%'OR -- Toad UPPER(v_prog) LIKE '%SQLPLUS%' -- SQLPLUS AND upper(v_mach) LIKE 'LIMITED\%' THEN DBMS_OUTPUT.PUT_LINE('yup output from trigger'); RAISE e_badlogin; END IF; EXCEPTION WHEN e_badlogin THEN -- DBMS_OUTPUT.PUT_LINE('yup output from trigger'); RAISE_APPLICATION_ERROR(-20000, 'This access is in violation of LTS compliance, audit, and IT Security Policies.!'||' User: '||v _user|| ' Program: '||v_prog); END; ============ Problem is, I can't from the trigger send back any message without killing the session. Dbms_output doesnot seem to work from inside this trigger (Should it?) . Can someone point me in the right direction here? There must be some way to send message to SQLplus user a message without killing the session. Brian
