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 :

END IF;

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

SELECT p.spid, v.program

AND v.sid = v_sid;

v_module || ' ' || v_action;

sys.dbms_system.ksdwrt(2, message);

ENDIF;

END;

2，执行报错信息：

Compilation errors for TRIGGERTIMDBA.LOGON_DENIED_TO_ALERT

Error: PL/SQL: ORA-00942: table or viewdoes not exist

Line: 20

Text: SELECT sid INTO v_sid FROMsys.v_$mystat WHERE rownum

解决办法

grant execute on sys.dbms_system to timdba;

3，再次执行还在报错：

Text: FROM v$process p, v$session v

Error: PL/SQL: SQL Statement ignored

Line: 21

Text: SELECT p.spid, v.program

解决办法：

grant select on sys.v_$mystat to timdba;

4，再次调试报错信息3

Compilation errors for TRIGGERTIMDBA.LOGON_DENIED_TO_ALERT

Line: 23

Text: FROM v$process p, v$session v

解决办法：

grant select on sys.v_$process to timdba;

grant select on sys.v_$session to timdba;
