1，触发器内容如下

CREATE OR REPLACE TRIGGER"LOGON_DENIED_TO_ALERT"

 AFTER servererror ON DATABASE

DECLARE

 message   VARCHAR2(168);

 ip        VARCHAR2(15);

 v_os_user VARCHAR2(80);

 v_module  VARCHAR2(50);

 v_action  VARCHAR2(50);

 v_pid     VARCHAR2(10);

 v_sid     NUMBER;

 v_program VARCHAR2(48);

BEGIN

  IF(ora_is_servererror(1017)) THEN

   -- get ip FOR remote connections :

   IF upper(sys_context(‘userenv‘, ‘network_protocol‘)) = ‘TCP‘ THEN

     ip := sys_context(‘userenv‘, ‘ip_address‘);

   END IF;

   SELECT sid INTO v_sid FROM sys.v_$mystat WHERE rownum < 2;

   SELECT p.spid, v.program

     INTO v_pid, v_program

     FROM v$process p, v$session v

    WHERE p.addr = v.paddr

      AND v.sid = v_sid;

   v_os_user := sys_context(‘userenv‘, ‘os_user‘);

   dbms_application_info.read_module(v_module, v_action);

   message := to_char(SYSDATE, ‘YYYYMMDD HH24MISS‘) ||

               ‘ logon denied from ‘ || nvl(ip,‘localhost‘) || ‘ ‘ ||

               v_pid || ‘ ‘ || v_os_user || ‘with ‘ || v_program || ‘ – ‘ ||
