oracle9下开启trace报错

wind_sand

按照网上的资料操作如下：
Connected to Oracle9i Enterprise Edition Release 9.0.1.1.1
Connected as SYS

SQL> @E:\oracle\ora90\rdbms\admin\utlxplan.sql;

Table created

SQL> @E:\oracle\ora90\sqlplus\admin\plustrce.sql;
drop role plustrace;

Role dropped
create role plustrace;

Role created
grant select on v_$sesstat to plustrace;

Grant succeeded
grant select on v_$statname to plustrace;

Grant succeeded
grant select on v_$session to plustrace;

Grant succeeded
grant plustrace to dba with admin option;

Grant succeeded
set echo off
  
SQL> grant plustrace to gf;

Grant succeeded

SQL> conn gf/gf
Connected to Oracle9i Enterprise Edition Release 9.0.1.1.1
Connected as gf

SQL> set autotrace traceonly;
Cannot SET AUTOTRACE

居然还是不行阿 我查看user_role_privs已经有了PLUSTRACE角色的权限了。不明白怎么还是不行，请高人指点一二！！
