例子：

exec sys.dbms_system.set_sql_trace_in_session(10 , 39196 , true);
exec sys.dbms_system.set_sql_trace_in_session(10 , 39196 , false);

SET_SQL_TRACE_IN_SESSION过程序要提供三个参数:

SQL> desc DBMS_SYSTEM.SET_SQL_TRACE_IN_SESSION;

Parameter Type Mode Default?

--------- ------- ---- --------

SID NUMBER IN

SERIAL# NUMBER IN

SQL_TRACE BOOLEAN IN

通过v$session我们可以获得sid、serial#等信息:

获得进程信息，选择需要跟踪的进程:

SQL> select sid,serial#,username from v$session

2 where username is not null;

SID SERIAL# USERNAME

---------- ---------- ------------------------------

8 2041 SYS

9 437 EYGLE

设置跟着:

SQL> exec dbms_system.set_SQL_TRACE_in_session(9,437,true)

PL/SQL procedure successfully completed.

….

可以等候片刻，跟踪session执行任务,捕获sql操作…

….

停止跟踪:

SQL> exec dbms_system.set_SQL_TRACE_in_session(9,437,false)

PL/SQL procedure successfully completed.
