OCM考试中Outline的配置

OCM考试中Outline的配置：

 

1）创建outline for CATEGORY default（sys用户）：     CREATE OUTLINE scott2      ON SELECT empno,ename FROM scott.emp3 where empno=7788; 

2）查询当前outline状态：    SQL> select name, category, owner,SQL_TEXT from dba_outlines;

     NAME                           CATEGORY   OWNER      SQL_TEXT------------------------------ ---------- ---------- ------------------------------      SCOTT2                         DEFAULT    SYS        SELECT empno,ename FROM scott.                                                           emp3 where empno=7788 

 3）让系统使用该outline，注意此声明对所有会话生效：    SQL> alter system set USE_STORED_OUTLINES = scott2;    或者只让某个会话生效：    SQL> alter session set USE_STORED_OUTLINES = scott2;
