1. 找出sid和serial#

select sid,serial#,osuser from v$session t
where t.USERNAME='USERNAME';

2. 开始sqltrace

execute dbms_system.set_sql_trace_in_session(sid,serial#,ture);

3. 运行程序

4. 停止sqltrace

execute dbms_system.set_sql_trace_in_session(sid,serial#,false);

5. 使用cmd 到udump

例: D:\Oracle\product\10.1.0\admin\test10g\udump

6. 找最新的trace文件

7. 使用tkprof文件解析trace文件

例: tkprof sqltrace文件.trc a.out

8. 打开a.out

--unix
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$process p
         WHERE m.statistic# = 1 AND s.SID = m.SID AND p.addr = s.paddr) p,
       (SELECT t.INSTANCE
          FROM v$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') d
/

--win
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$process p
         WHERE m.statistic# = 1 AND s.SID = m.SID AND p.addr = s.paddr) p,
       (SELECT t.INSTANCE
          FROM v$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') d
/
