ORA01919:role'OLAPI_TRACE_USER'doesnotexist

我在用数据泵导入数据的时候报的错

TEST_USER1@ORCL> conn / as sysdba
SYS@ORCL> grant plustrace to TEST_USER1;
grant plustrace to TEST_USER1
*
ERROR at line 1:
ORA-01919: role &＃8216;PLUSTRACE&＃8217; does not exist
SYS@ORCL> select * from dba_roles where role=&＃8217;PLUSTRACE&＃8217;;
no rows selected

2、 建立角色
SYS@ORCL>@?/sqlplus/admin/plustrce.sql &＃8211;以下内容自动执行

SQL>
SQL> drop role plustrace;
drop role plustrace
*
ERROR at line 1:
ORA-01919: role &＃8216;PLUSTRACE&＃8217; 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.

3. 赋予权限
SQL> grant plustrace to dba with admin option;

Grant succeeded.

4.进行查看

SQL> select * from dba_roles where role=&＃8217;PLUSTRACE&＃8217;;

ROLE PASSWORD AUTHENTICAT
&＃8212;&＃8212;&＃8212;&＃8212;&＃8212;&＃8212;&＃8212;&＃8212;&＃8212;&＃8212; &＃8212;&＃8212;&＃8211; &＃8212;&＃8212;&＃8212;&＃8211;
PLUSTRACE NO NONE
