autotrace是SQL*PLUS中的一个工具,可以显示所执行查询的解释计划(explain plan)以及所用的资源。

(如果是其它版本的话可能要先执行/rdbms/admin/utlxplan.sql;再create public synonym plan_table for plan_table;)

grant all on plan_table to public;

运行sqlplus/admin/plustrace.sql;内容如下:  Copyright (c) Oracle Corporation 1995, 2002. All Rights Reserved.

    the AUTOTRACE feature should be granted the PLUSTRACE role by
    the DBA.

    set echo on
    drop role plustrace;
    create role plustrace;
