一次数据表的导入导出操作在使用impdp导入的时候遇到了ORA-39154,花了点时间解决了。
下面我在测试环境里真实还原了这个错误,并附上解决思路和方案

#####创建测试表,不过表上的索引建在另一个schema下
sqlplus ad/123456
 create table adtab1 tablespace ts_pub as select * from all_users;
 SQL> select count(*) from adtab1;


  COUNT(*)
 ----------
        45


 sqlplus mng/789012
 create index ind_adtab1_uid on ad.adtab1(user_id);
 create index ind_adtab1_crt on ad.adtab1(created);


#####在expdp所连的源库及impdp所连的目标库上都要创建好Directory对象,并且赋予执行用户ad对于directory的读写权限
sqlplus '/as sysdba'
 create or replace directory tmpdir as '/home/Oracle/chh/';
 grant read,write on directory tmpdir to ad;


#####以sysdba身份将表从源库导出
expdp \"/ as sysdba\" tables=ad.adtab1 directory=tmpdir dumpfile=ad.adtab1.dmp logfile=exp_ad.adtab1.log reuse_dumpfiles=yes


---导出过程正常
Starting "SYS"."SYS_EXPORT_TABLE_01":  "/******** AS SYSDBA" tables=ad.adtab1 directory=tmpdir dumpfile=ad.adtab1.dmp logfile=exp_ad.adtab1.log reuse_dumpfiles=yes

  /home/oracle/chh/ad.adtab1.dmp
 Job "SYS"."SYS_EXPORT_TABLE_01" successfully completed at 08:17:27


#####将dmp文件传输到目标库后以ad用户执行impdp
 REVOKE IMP_FULL_DATABASE FROM AD;
 impdp ad/123456 directory=tmpdir dumpfile=ad.adtab1.dmp logfile=imp_ad.adtab1.log


---导入过程中出现ORA-39154错误,提示导入的内容里包含有不属于AD用户的对象,这部分对象没有能够正常导入,但ad.adtab1表已经导入成功了
ORA-39154: Objects from foreign schemas have been removed from import
 Master table "AD"."SYS_IMPORT_FULL_01" successfully loaded/unloaded

出错原因分析:
因为导入的内容里包括了统计信息,统计信息的相关操作在导入的过程中是在sys.impdp_stats表里进行的(从后面impdp生成的sql脚本里可以看出来),ad用户需要赋予imp_full_database权限才能导入这部分统计信息,这应该就是ORA-39154的成因


---索引没有导入进去
SQL> select count(*) from adtab1;


  COUNT(*)
 ----------
        45


 SQL> select index_name,table_name from dba_indexes where table_name='ADTAB1';


 no rows selected


#####赋给ad用户imp_full_database权限后再次进行impdp,这回ORA-39083取代了ORA-39154,问题出在为MNG.IND_ADTAB1_UID、MNG.IND_ADTAB1_CRT两个索引生成统计信息时发现这两个索引并不存在,至此我们才发现了索引和表不在同一个schema的问题:表在ad用户下,而索引却建在了mng用户下,这可能是开发人员的一个失误,我们暂且不讨论这样建索引是否合理。
grant imp_full_database to ad;
