Oracle-impdp 按照用戶導出,導入后發現存在部分索引不存在，缺失索引是關聯其它用戶創建的？

 

疑問：Oracle-impdp 按照用戶導出,導入后發現存在部分索引不存在，缺失索引是關聯其它用戶創建的？

？？？

如下測試一下：

11G 單實例測試了一下，數據泵按照用戶導出，如果存在用戶索引關聯其它用戶的表，不會被導入；

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);
