Oracle报EXP-0006:出现内部不一致的错误

14年10月份到电子所部署系统时，用exp、imp导库命令成功的实现了Oracle数据库的导出、导入，对此，还专门发表过一篇文章Oracle数据库导出导入，讲解导出、导入过程，见 。

昨天再对服务器新安装的Oracle数据库用exp、imp导库，一直报“EXP-0006：出现内部不一致的错误”，于是在网上百度，尝试其他导库方式，发现采用expdp、impdp数据泵同样可以完成数据库的导出、导入，而且数据泵与传统导出导入有如下区别：

1.EXP和IMP是客户段工具程序， EXPDP和IMPDP是服务端的工具程序；

2.EXP和IMP效率比较低. EXPDP和IMPDP效率高；

3.数据泵功能强大并行、过滤、转换、压缩、加密、交互等等；

4.数据泵不支持9i以前版本， EXP/IMP短期内还是比较适用；

5.同exp/imp数据泵导出包括导出表,导出方案,导出表空间,导出数据库4种方式。

有了理论支持，下面开始实战。

expdp导出Oracle数据库

1.在sqlplus下创建Directory，优点在于让我们可以在Oracle数据库中灵活的对文件进行读写操作，，极大的提高了Oracle的易用性和可扩展性。

命令：createdirectory oracleDB as 'D:\OracleDB';

2.把读写权限授予特定用户

命令：Grantread,write on directory oracleDB to radpcs;

3.在dos窗口执行expdp导出命令

命令：expdp radpcs/ictradpcs@rdpcs directory=oracleDB dumpfile =20150226.dmp logfile=20150226.logFULL=y;

到此导出工作完成，下面讲解如何用impdp导入Oracle数据库。

impdp导入Oracle数据库

1.以sysdba级别登录Oracle数据库

命令：--sqlplus /nolog

--conn system/system@radpcs as sysdba

2.创建数据表空间

命令：

--创建数据表空间

CREATE TABLESPACE RADPCS_DATA

LOGGING

DATAFILE 'D:\OracleDB\radpcs_DATA.DBF' SIZE 200M REUSE AUTOEXTEND

ON NEXT 10M MAXSIZE 16383M EXTENT MANAGEMENT LOCAL UNIFORM

SIZE 1024K;

--创建索引表空间

CREATE TABLESPACE RADPCS_INDX

LOGGING

DATAFILE 'D:\OracleDB\radpcs_INDX.DBF' SIZE 200M REUSE AUTOEXTEND

ON NEXT 10M MAXSIZE 16383M EXTENT MANAGEMENT LOCAL UNIFORM

SIZE 1024K;

这步很关键，创建的表空间需要和原Oracle表空间名称、个数相同，否则会导入失败。如果不知道原表空间名称、个数，就先创建一个临时的表空间进行导入，导入过程中根据错误提示，比如“RADPCS1_DATA表空间不存在”提示，缺哪个创建哪个。

3.创建用户、对用户授权

--创建用户
create user radpcs identified by ictradpcs
default tablespace radpcs_data
quota unlimited on radpcs_data
quota unlimited on radpcs_indx;

--授权

4.在sqlplus下创建Directory

命令：createdirectory oracleDB as 'D:\OracleDB';

5.把读写权限授予特定用户

命令：Grantread,write on directory oracleDB to radpcs;

6.在dos窗口执行impdp导入命令

命令：impdp radpcs/ictradpcs@rdpcs directory=oracleDB dumpfile=20150226.dmp logfile=20150226.log;

漫长的等待后，dos窗口会提示导出完成。如果导入过程出错，会提示错误信息（只要数据完整，一些错误可以忽略）。
