Oracle-impdp 按照用户导出,导入后发现存在部分索引不存在，缺失索引是关联其它用户创建的？

疑问：Oracle-impdp 按照用户导出,导入后发现存在部分索引不存在，缺失索引是关联其它用户创建的？

？？？

如下测试一下：

11G 单实例测试了一下，数据泵按照用户导出，如果存在用户索引关联其它用户的表，不会被导入；

SQL> show user
USER is “SYS”
SQL> create table system.test1 tablespace users as select * from dba_objects;
SQL> grant select on system.test1 to test_usr;
SQL> create table system.test2 as select * from dba_objects;
SQL> grant select on system.test2 to test_usr;
SQL> select tablespace_name from dba_segments where owner=‘SYSTEM’ and segment_name=‘TEST2’;
TABLESPACE_NAME
SYSTEM

SQL> create index test_usr.ind_object_id on system.test1(object_id);
SQL> create index test_usr.ind_object_id2 on system.test2(object_id);
