RAC 实例 迁移到 单实例 -- 使用导出导入

昨天整理做了用导出导入的方法，将Oracle单实例迁移到RAC实例的实验。今天来做一个用导出导入的方法将RAC实例迁移到Oracle单实例。方法都差不多。只不过顺序倒过来了。

Oracle单实例迁移到RAC实例--使用导出导入方法

http://blog.csdn.net/xujinyang/article/details/6837071

昨天用的是数据泵（expdp/impdp）来导的，今天用逻辑导出导入(exp/imp)来做这个实验。数据泵它有很大的局限性，它只能在服务器端执行。

接着昨天的那个实验做，用户，表空间就不在创建了，还用昨天的Dave用户和Tianlesoftware表空间。

实验步骤：

1.在RAC实例上创建一下对象

2.用exp将实例导出

3.导入前的准备工作

4.imp导入单实例。

5.检查无效对象

一．在RAC实例上创建一些对象

1.1RAC状态

[oracle@rac1 ~]$cd /u01/app/oracle/product/crs/bin/

[oracle@rac1 bin]$crs_stat -t

NameTypeTargetStateHost

1.2连接实例，创建对象

[oracle@rac2 ~]$ export ORACLE_SID=orcl2

[oracle@rac2 ~]$ sqlplus /nolog

二．Exp导出数据

这里我们按照用户的模式来导。导出dave用户的数据，然后导入dave用户的数据。

[oracle@rac1 bin]$export ORACLE_SID=orcl1

[oracle@rac1 bin]$exp dave/dave owner=dave file=/u01/dave_2010929.dmp log=/u01/dave.log;

Export: Release 10.2.0.1.0 - Production on Tue Sep 28 22:39:11 2010

导出成功，dump文件放在/u01目录下。

三．导入前的主备工作

如果导入的用户和表空间已经在单实例上存在，那么我们最好清空用户的所有对象。

如果单实例上没有，那么就需要创建用户，及相关的表空间。

这里模拟用户和表空间不存在的情况。我们会在单实例上创建用户Dave和对应的表空间。

SQL> select file_name from dba_data_files;

FILE_NAME

--------------------------------------------------------------------------------

D:/APP/ADMINISTRATOR/ORADATA/ORCL/USERS01.DBF

D:/APP/ADMINISTRATOR/ORADATA/ORCL/UNDOTBS01.DBF

D:/APP/ADMINISTRATOR/ORADATA/ORCL/SYSAUX01.DBF

D:/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。

四．导入数据

4.1将RAC实例的dump文件copy到单实例

[oracle@rac1 bin]$cd /u01

[oracle@rac1 u01]$ls

appdave.logRAC_hot_database_backup.sh

backupdave.oraRAC_hot_database_backup.sh.out

dave_2010929.dmpimpdp.logtianlesoftware.dmp

[oracle@rac1 u01]$scp dave_2010929.dmp 10.85.10.15://u01

The authenticity of host '10.85.10.15 (10.85.10.15)' can't be established.

RSA key fingerprint is 7b:f7:26:7e:6b:2a:1f:6b:67:f9:cc:4e:67:07:91:d1.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added '10.85.10.15' (RSA) to the list of known hosts.

oracle@10.85.10.15's password:

dave_2010929.dmp100%16KB16.0KB/s00:00

4.2用imp导入数据

[oracle@localhost ~]$export ORACLE_SID=orcl

[oracle@localhost ~]$imp dave/dave fromuser=dave touser=dave file=/u01/dave_2010929.dmp log=/u01/dave.log;

Import: Release 10.2.0.1.0 - Production on Wed Sep 29 01:42:00 2010

Copyright (c) 1982, 2005, Oracle.All rights reserved.

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, OLAP and Data Mining options

Export file created by EXPORT:V10.02.01 via conventional path

. . importing table"DBA"22 rows imported

. . importing table"USERINFO"2 rows imported

Import terminated successfully without warnings.

五．检查无效对象

具体参考：

Oracle Compile编译无效对象

http://blog.csdn.net/xujinyang/article/details/6830032

SQL>select 'ALTER ' || OBJECT_TYPE || ' '||owner||'.' || OBJECT_NAME || ' COMPILE;' fromall_objects wherestatus = 'INVALID' andobject_type in ('PACKAGE','FUNCTION','PROCEDURE', 'TABLE', 'VIEW', 'SEQUENCE', 'TRIGGER');

no rows selected

SQL>select 'ALTER PACKAGE ' || OWNER||'.'|| OBJECT_NAME || ' COMPILE body;' from ALL_objects where status = 'INVALID' and object_type in ('PACKAGE BODY');

no rows selected

没有无效对象，验证下导入的数据：

SQL> conn dave/dave;

Connected.

SQL> select * from dba;

USERNAMEUSER_ID CREATED

导入已经完成，和普通的导出导入没有什么区别。
