ORA-01919: role ‘PLUSTRACE’ does not exist

环境：Oracle 10g,11g. 现象：在一次迁移测试中，发现有这样的角色赋权会报错不存在： SYS@orcl> grant PLUSTRACE to jingyu; grant PLUSTRACE to jingyu       * ERROR at line 1: ORA-01919: role 'PLUSTRACE' does not exist

查询发现这个角色是需要手工执行脚本创建，直接执行Oracle自带的SQL脚本@?/sqlplus/admin/plustrce.sql即可： SYS@orcl> @?/sqlplus/admin/plustrce.sql SYS@orcl> SYS@orcl> drop role plustrace; drop role plustrace           * ERROR at line 1: ORA-01919: role 'PLUSTRACE' does not exist

SYS@orcl> create role plustrace;

Role created.

SYS@orcl> SYS@orcl> grant select on v_$sesstat to plustrace;

Grant succeeded.

SYS@orcl> grant select on v_$statname to plustrace;

Grant succeeded.

SYS@orcl> grant select on v_$mystat to plustrace;

Grant succeeded.

SYS@orcl> grant plustrace to dba with admin option;

Grant succeeded.

SYS@orcl> SYS@orcl> set echo off SYS@orcl>

可以看到这个角色就是封装了对v_$sesstat，v_$statname，v_$mystat这几个视图的查询权限。

执行以后就可以直接赋予用户PLUSTRACE的角色了： SYS@orcl> grant PLUSTRACE to jingyu;

Grant succeeded.
