1.安裝dbms_support包
 

SQL> @?/rdbms/admin/dbmssupp.sql

Package created.


Package body created.

SQL> grant execute on dbms_support to dairy;

2.找到需要跟蹤的會話

SQL> alter session set nls_date_format='YYYY-MM-DD HH24:MI:SS';

Session altered.

SQL> select sid,serial#,logon_time from v$session where audsid=userenv('sessionid');

       SID    SERIAL# LOGON_TIME
---------- ---------- -------------------
      2845     1649 2018-10-18 09:50:40
 

3.使用start_trace_in_session進行跟蹤

SQL> exec dbms_support.start_trace_in_session(2845,1649,TRUE,TRUE);

PL/SQL procedure successfully completed.

4.開始跟蹤後，在客戶端進行對應的操作。

5.使用stop_trace_in_session結束跟蹤
.

SQL> exec dbms_support.stop_trace_in_session(2845,1649);

PL/SQL procedure successfully completed
 

6.使用以下的語句獲得trace檔案的位置。

SELECT    d.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$process p
         WHERE m.statistic# = 1 AND s.SID = &SID AND p.addr = s.paddr) p,
       (SELECT t.INSTANCE
          FROM v$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') d
        
SQL> SELECT    d.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$process p
         WHERE m.statisti  2    3    4    5    6    7    8    9   10  c# = 1 AND s.SID = '2845' AND p.addr = s.paddr) p,
       (SELECT t.INSTANCE
          FROM v$thread t, v$parameter v
         WHERE     v.NAME = 'thread'
               AND (v.VALUE = 0 OR t.thread# = TO_NUMBER (v.VALUE))) i,
       (SELECT VALUE
         11   12   13   14   15   16    FROM v$parameter
         WHERE NAME = 'user_dump_dest') d 17  ;

TRACE_FILE_NAME
--------------------------------------------------------------------------------
/home/u01/app/oracle/diag/rdbms/foidndb/foidndb/trace\foidndb_ora_19143.trc   
 

7.使用TKPROF將trace檔案轉換成為執行計劃解析的文字。
 

[[email protected] db_1]$ tkprof /home/u01/app/oracle/diag/rdbms/foidndb/foidndb/trace/foidndb_ora_19143.trc /u01/test.txt
