4.3跟踪其它用户的进程，在很多时候我们需要跟踪其它用户的进程，而不是当前用户，可以通过ORACLE提供的系统包
DBMS_SYSTEM.SET_SQL_TRACE_IN_SESSION来完成。
例如：
代码如下:
SELECT SID, SERIAL#, USERNAME FROM V$SESSION WHERE USERNAME = 'ETL'
EXEC DBMS_SYSTEM.SET_SQL_TRACE_IN_SESSION(61,76,TRUE);
EXEC DBMS_SYSTEM.SET_SQL_TRACE_IN_SESSION(61,76,FALSE);
5 利用10046事件
代码如下:
ALTER SESSION SET TRACEFILE_IDENTIFIER = 10046;
ALTER SESSION SET EVENTS='10046 trace name context forever, level 8';
SELECT * FROM SCOTT.EMP;
ALTER SESSION SET EVENTS ='10046 trace name context off';
然后你可以用脚本查看追踪文件的位置
SELECT T.VALUE || '/' || LOWER(RTRIM(I.INSTANCE, CHR(0))) || '_ora_' ||
P.SPID || '.trc' TRACE_FILE_NAME
FROM
( SELECT P.SPID
FROM V$MYSTAT M, V$SESSION S, V$PROCESS P
WHERE M.STATISTIC# =1
AND S.SID = M.SID
AND P.ADDR = S.PADDR
) P,
( SELECT T.INSTANCE
FROM V$THREAD T, V$PARAMETER V
WHERE V.NAME ='thread'
AND (V.VALUE = 0 OR T.THREAD# = TO_NUMBER(V.VALUE))
) I,
(SELECT VALUE FROM V$PARAMETER WHERE NAME='user_dump_dest') T
查询结果为wgods_ora_28279.trc文件， 但是去相应目录却没有找到对应的追踪文件，而是如下trace文件： wgods_ora_28279_10046.trc6 利用10053事件 上一页 [1] [2] [3] [4] [5] [6] [7] [8] 下一页
