如何将Oracle 11g备份导入到10g
如何将Oracle 11g备份导入到10g ,10g 导入语句:IMPDP USERID=
二、在10g服务器上,使用impdp命令恢复数据
准备工作:1.建库2.建表空间3.建用户并授权4.将aa.dmp拷贝到10g的dpdump目录下
--创建表空间
createtablespace TS_Facial datafile'E:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\Facial.DBF' size 500M autoextend on next50M;
--创建用户
create user Facial identified by Facial default tablespace TS_Facial;
--授权给用户
grantconnect,resource,dba to Facial;
aa.dmp和 aa.log 放在E:\oracle\product\10.2.0\admin\orcl\dpdump目录下
在用expdp的时候可能会报错,,在metink上和盖总哪儿都找到了解决方法

ORA-39006:internal error
ORA-39213:Metadata processing is not available
Metalink确认是一个又来已经的已知问题,可以尝试执行如下步骤解决:
connect/ as sysdba
executesys.dbms_metadata_util.load_stylesheets;
我的系统中,以上处理过程有效:
OracleDatabase 10g Enterprise Edition Release 10.2.0.2.0 - Production
Withthe Partitioning, OLAP and Data Mining options
SQL>exec dbms_metadata_util.load_stylesheets
