ORA-01919: role 'OLAPI_TRACE_USER' does not exist

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 ‘PLUSTRACE’ does not exist
SYS@ORCL> select * from dba_roles where role=’PLUSTRACE’;
no rows selected

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

SQL>
SQL> drop role plustrace;
drop role plustrace
*
ERROR at line 1:
ORA-01919: role ‘PLUSTRACE’ 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=’PLUSTRACE’;

ROLE PASSWORD AUTHENTICAT
—————————— ——– ———–
PLUSTRACE NONONE
