Oracle 9i 查看执行计划报错 ORA-02402: PLAN_TABLE not found

查看sql的执行计划遇到如下报错：

sys@im1>explain plan for SELECT JOB, LOG_USER, SCHEMA_USER FROM DBA_JOBS;

explain plan for SELECT JOB, LOG_USER, SCHEMA_USER FROM DBA_JOBS

                                                      *

ERROR at line 1:

ORA-02402: PLAN_TABLE not found

sys@im1>set autot trace on;

SP2-0613: Unable to verify PLAN_TABLE format or existence

SP2-0611: Error enabling EXPLAIN report

sys@im1>exit

该错误的的主要原因是由于当前用户下没有PLAN_TABLE这张表及相应的PLUSTRACE角色权限。

解决方法就是直接创建此表和对应的PLUSTRACE角色即可

1 以sys 用户登录数据库，运行utlxplan.sql脚本创建 PLAN_TABLE并赋予相关权限，以便让其他用户使用
