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

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

 

 

平常都用sys，system用户使用autotrace,今天使用其他用户执行set autotrace 的时候报错：
SP2-0618: Cannot find the Session Identifier.  Check PLUSTRACE role is enabled
SP2-0611: Error enabling STATISTICS report

是该用户没有授予PLUSTRACE这个角色的权限。
SYS AS SYSDBA@oemrep>grant PLUSTRACE to test2;
grant PLUSTRACE to test2
      *
ERROR at line 1:
ORA-01919: role 'PLUSTRACE' does not exist

授权发现PLUSTRACE角色不存在，查看官方文档后执行以下sql
SYS AS SYSDBA@oemrep>@$ORACLE_HOME/sqlplus/admin/plustrce.sql
SYS AS SYSDBA@oemrep>
SYS AS SYSDBA@oemrep>drop role plustrace;
drop role plustrace
          *
ERROR at line 1:
ORA-01919: role 'PLUSTRACE' does not exist

SYS AS SYSDBA@oemrep>create role plustrace;

Role created.
SYS AS SYSDBA@oemrep>
SYS AS SYSDBA@oemrep>grant select on v_$sesstat to plustrace;

Grant succeeded.
SYS AS SYSDBA@oemrep>grant select on v_$statname to plustrace;

Grant succeeded.
SYS AS SYSDBA@oemrep>grant select on v_$mystat to plustrace;

Grant succeeded.
SYS AS SYSDBA@oemrep>grant plustrace to dba with admin option;

Grant succeeded.
SYS AS SYSDBA@oemrep>grant PLUSTRACE to test2;

Grant succeeded.

至此，问题解决。
