SQL*Plus环境下创建PLUSTRACE角色

普通用户在SQL*Plus中开启AUTOTRACE报告时，遇到SP2-0618: Cannot find the Session Identifier. Check PLUSTRACE role is enabled错误。如下所示：

SQL>

SQL> set autotrace on;

SP2-0618: Cannot find the Session Identifier. Check PLUSTRACE role is enabled

SP2-0611: Error enabling STATISTICS report

SQL>

此时应该检查数据库是否已经创建了角色PLUSTRACE，使用下面脚本检查角色PLUSTRACE是否存在。

SELECT * FROM DBA_ROLES WHERE ROLE='PLUSTRACE'

如果角色不存在，应该去$ORACLE_HOME/sqlplus/admin/目录下，你会找到plustrce.sql脚本文件。

[oracle@db-server ~]$ cd $ORACLE_HOME/sqlplus/admin/

[oracle@db-server admin]$ ls

glogin.sql  help  iplus  libisqlplus.def  libsqlplus.def  plustrce.sql  pupbld.sql

[oracle@db-server admin]$ more plustrce.sql

-- DESCRIPTION

--   Creates a role with access to Dynamic Performance Tables

--   for the SQL*Plus SET AUTOTRACE ... STATISTICS command.

--   After this script has been run, each user requiring access to

--   the AUTOTRACE feature should be granted the PLUSTRACE role by

--   the DBA.

--

-- USAGE

--   sqlplus "sys/knl_test7 as sysdba" @plustrce

--

--   Catalog.sql must have been run before this file is run.

--   This file must be run while connected to a DBA schema.

set echo on

drop role plustrace;

create role plustrace;

grant select on v_$sesstat to plustrace;

grant select on v_$statname to plustrace;

grant select on v_$mystat to plustrace;

grant plustrace to dba with admin option;

set echo off

执行该脚本就会创建角色PLUSTRACE，如下所示。然后将该角色授予对应用户即可。
