Oracle 单实例 迁移到 RAC 实例 - 使用导出导入方法Oracle 单实例 迁移到 RAC 实例 - 使用导出导入方法将Oracle 单实例迁移到 RAC 实例上有两种方法：1. 使用RMAN 复制2. 使用逻辑导出导入（exp/imp） 或者 数据泵（expdp/impdp）这篇演示用数据泵（expdp/impdp）将单实例迁移到RAC 环境。 导出导入schema方式来进行。逻辑导出导入相对数据泵而言，更简单一点。 这里假设RAC 环境已经搭建好了。 如果没有搭建好，可以参考我的Blog： Redhat 5.4 + ASM + RAW+ Oracle 10g RAC 安装文档http:/blog.csdn.net/tianlesoftware/archive/2010/09/09/5872593.aspx导出导入参考： Oracle 10g EXPDP和IMPDP使用说明http:/blog.csdn.net/tianlesoftware/archive/2009/10/16/4674224.aspxORACLE 数据库逻辑备份 简单 EXP/IMP http:/blog.csdn.net/tianlesoftware/archive/2009/10/24/4718366.aspx测试过程如下：1. 现在本地库上创建用户Dave, 与值对应的表空间。2. 用Dave 登陆，创建相关的表。3. 将Dave用户的表空间导出4. 将dump文件导入到RAC 实例一 在本地库上创建表空间，用户SQL> select file_name from dba_data_files;FILE_NAME-D:/APP/ADMINISTRATOR/ORADATA/ORCL/USERS01.DBFD:/APP/ADMINISTRATOR/ORADATA/ORCL/UNDOTBS01.DBFD:/APP/ADMINISTRATOR/ORADATA/ORCL/SYSAUX01.DBFD:/APP/ADMINISTRATOR/ORADATA/ORCL/SYSTEM01.DBFD:/APP/ADMINISTRATOR/ORADATA/ORCL/DAVE0.DBFD:/APP/ADMINISTRATOR/ORADATA/ORCL/DBA1.DBFD:/APP/ADMINISTRATOR/ORADATA/ORCL/CATALOG1.DBFD:/APP/ADMINISTRATOR/ORADATA/ORCL/CATALOG_TS1.DBF已选择8行。SQL> create tablespace tianlesoftware datafile D:/APP/ADMINISTRATOR/ORADATA/ORCL/tianlesoftware.dbf size 50m;表空间已创建。SQL> create user dave identified by dave default tablespace tianlesoftware temporary tablespace temp;用户已创建。SQL> grant dba to dave;授权成功。SQL> grant connect to dave;授权成功。SQL> grant resource to dave;授权成功。SQL>二 用dave登陆，创建相关表SQL> create table userinfo(name varchar2(10),hometown varchar2(20);表已创建。SQL> insert into userinfo values(dave,安徽省安庆市怀宁县);已创建 1 行。SQL> commit;提交完成。SQL> insert into userinfo values(Tianle,安徽省安庆市怀宁县);已创建 1 行。SQL> commit;提交完成。SQL> select * from userinfo;NAME HOMETOWN- -dave 安徽省安庆市怀宁县Tianle 安徽省安庆市怀宁县SQL>三 用数据泵导出Dave 用户的表空间3.1 创建directory 并赋权SQL> conn / as sysdba;已连接。SQL> create directory backup as e:/tmp;目录已创建。SQL> grant read,write on directory backup to dave;授权成功。SQL> select * from dba_directories;OWNER DIRECTORY_NAME DIRECTORY_PATH- - -SYS BACKUP e:/tmp3.2 导出Dave schema - - - SCHEMA 与用户对应oraclelocalhost $ expdp dave/dave DIRECTORY=backup DUMPFILE=tianlesoftware.dmp SCHEMAS=Dave logfile=exp.log;Export: Release 10.2.0.1.0 - Production on Tuesday, 28 September, 2010 15:12:36Copyright (c) 2003, 2005, Oracle.
