1)10046論斷事件

設置方法：

全局設置：初始參數文件中設置event="10046 trace name context forever,level 12"

本地session設置：alter session set events '10046 trace name context forever, level 8'

其它session設置：通過DBMS_SYSTEM.SET_EV系統包實現,需要通過v$session得到sid,serial#

這裡我使用的是本地session設置：

ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 4';

select object_name from maggie.obj where object_id=:V1;

運行，為變量V1賦值28221，運行完成

然後關閉踉蹌事件alter session set events '10046 trace name context off';

在user_dump_file參數指定的目錄下找到生成的udump文件，找到以下結果：

我們可以看到V1變量的值為28221

補充：10046事件可以设置以下四个级别，如果要獲取綁定變量的值，至少要設置level 4

1 -標準的SQL_TRACE功能，等價於sql_trace

4 - Level 1加上綁定值(bind values)

8 - Level 1 +等待事件

12 - Level 1 + Level 4 + Level 8

2)10G裡新增的VIEW：V$SQL_BIND_CAPTURE

運行SQL語句

SELECTnext_station, wip_d_sn_master.ROWID

FROMwip_d_sn_master

WHERE(serial_number = :V00001 OR carton_no = :V00002) AND ROWNUM = 1;

輸入變量值CK001L296J021Y，CMI0461000000140000027

在v$sql中找到剛剛運行的這個SQL的hash_value:

select sql_id, sql_text, bind_data,HASH_VALUE from v$sql

where sql_text Like 'SELECTnext_station, wip_d_sn_master.ROWID%';

得到的值為476601873，代入v$sql_bind_capture中查找出綁定變量的值

SELECT hash_value,sql_id,NAME,POSITION,DATATYPE_STRING,LAST_CAPTURED,value_string FROM v$sql_bind_capture

WHERE hash_value = 476601873

HASH_VALUE SQL_ID NAME POSITION DATATYPE_STRING LAST_CAPTURED VALUE_STRING
