【ERROR】非DBA用户要使用autotrace功能,报错(SP2-0618:和SP2-0611:和ORA-01919)

一、问题描述
     使用sqlplus时,连接到业务用户时,想查看某SQL的执行计划,报【SP2-0618: Cannot find the Session Identifier.  Check PLUSTRACE role is enabled】和【SP2-0611: Error enabling STATISTICS report】,通过相关文档检索后得知原因是缺少plus trace ROLE的权限,解决思路:赋予用户plustrace 权限即可。 

二、操作过程
1.登录用户,打开autotrace功能时报错
[oracle@db2 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4.0 Production on Mon Mar 21 09:29:29 2016

Copyright (c) 1982, 2013, Oracle.  All rights reserved.

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> conn ptpcpuser
Enter password:
Connected.

SQL> set autot on
SP2-0618: Cannot find the Session Identifier.  Check PLUSTRACE role is enabled
SP2-0611: Error enabling STATISTICS report

2.给用户赋予plustrace权限,报错【ORA-01919: role 'PLUSTRACE' does not exist】该角色不存在
SQL> conn / as sysdba
Connected.

SQL >grant plustrace to scott;
grant plustrace to scott
      *
ERROR at line 1:
ORA-01919: role 'PLUSTRACE' does not exist

3.安装plustrce包,建立plustrace角色,执行$ORACLE_HOME/sqlplus/admin/plustrce.sql包
SQL >conn / as sysdba
Connected.

SQL >@?/sqlplus/admin/plustrce.sql
SQL >
SQL >drop role plustrace;
drop role plustrace
          *
ERROR at line 1:
ORA-01919: role 'PLUSTRACE' does not exist

SQL >create role plustrace;

Role created.

SQL >
SQL >grant select on v_$sesstat to plustrace;

Grant succeeded.

SQL >grant select on v_$statname to plustrace;

Grant succeeded.

SQL >grant select on v_$mystat to plustrace;

Grant succeeded.

SQL >grant plustrace to dba with admin option;

Grant succeeded.

SQL >
SQL >set echo off
SQL >

4.给用户赋予plustrace权限成功
SQL> grant plustrace to ptpcpuser;

Grant succeeded.

5.连接该用户,并且打开autotrace成功
SQL> conn ptpcpuser
Enter password:
Connected.

SQL> set autot trace
SQL> select nvl(SUM(t.bean_count), 0)/100 from bean_record t WHERE t.invest_multip > 1 AND t.status = '2';

三、总结
     此问题有两个知识点,(1)是用户缺少set autotrace的权限,(2)是数据库缺少角色plustrace。这个问题对DBA来讲不是什么难事,但是还是要注意权限的管理与回收。继续学习喽,下回见。
