1、 本想使用dbms_advisor做一个sql access advisor测试,不料却遇ORA-13600 QSM-00794报错,如下:
SQL> DECLARE 2 task_name VARCHAR2(200); 3 BEGIN 4 task_name := 'My_Task'; 5 DBMS_ADVISOR.QUICK_TUNE(DBMS_ADVISOR.SQLACCESS_ADVISOR,'My_Task', 6 'select * from system.litest_8 where object_id=20'); 7 END; 8 / DECLARE * ERROR at line 1: ORA-13600: error encountered in Advisor QSM-00794: the statement can not be stored due to a violation of the invalid table reference filter ORA-06512: at "SYS.PRVT_ACCESS_ADVISOR", line 1809 ORA-06512: at "SYS.WRI$_ADV_SQLACCESS_ADV", line 180 ORA-06512: at "SYS.PRVT_ADVISOR", line 3678 ORA-06512: at "SYS.DBMS_ADVISOR", line 711 ORA-06512: at line 5 |
注意上面标红色部分,表的schema为system
2、上metalink上查原因,发现有文章ID:403358.1中做了详细原因描述
SQL Access Advisor maintains an internal list of non-tunable tables regardless of the contents of |
看来原因是因为dbms_advisor.quick_tune不支持为SYS和SYSTEM两个用户的表的顾问功能了。
3、将测试的表改到其他用户下试试
3.1 在litest这个用户下创建表
SQL> create table litest.litest_8 asselect * from system.litest_8
3.2 重新用DBMS_ADVISOR.QUICK_TUNE使用sql access advisor功能
SQL> DECLARE 2 task_name VARCHAR2(200); 3 BEGIN 4 task_name := 'My_Task'; 5 DBMS_ADVISOR.QUICK_TUNE(DBMS_ADVISOR.SQLACCESS_ADVISOR,'My_Task', 6 'select * from litest.litest_8 where object_id=20'); 7 END; 8 /
PL/SQL procedure successfully completed. |
注意上面标绿色部分,更换成了litest(非SYS或SYSTEM用户了)
