• 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);
