最近做了个oracle 10g数据冷迁移，很简单，但还是写一下基本的操作过程： 首先是准备迁移目标服务器，初始化环境，安装数据软件。 基本的环境初始化、依赖包先安装好、相关目录、用户都需要安装好(目标机器环境要与原一样)，安装数据库软件我是采用的clone

最近做了个oracle 10g数据冷迁移，很简单，但还是写一下基本的操作过程：

首先是准备迁移目标服务器，初始化环境，安装数据软件。

基本的环境初始化、依赖包先安装好、相关目录、用户都需要安装好(目标机器环境要与原一样)，安装数据库软件我是采用的clone，将线上的product目录打包传到目标服务器。

WARNING:A new inventory has been created in this session. However, it has not yet been registered as the central inventory of this system.

To register the new inventory please run the script '/U01/app/oracle/oraInventory/orainstRoot.sh' with root privileges.

If you do not register the inventory, you may not be able to update or patch the products you installed.

The following configuration scripts need to be executed as the "root" user.

/U01/app/oracle/oraInventory/orainstRoot.sh

/U01/app/oracle/product/10.2.0/db_1/root.sh

To execute the configuration scripts:

1. Open a terminal window

2. Log in as "root"

3. Run the scripts

The cloning of db_1 was successful.

Please check '/U01/app/oracle/oraInventory/logs/cloneActions......PM.log' for more details.

9.run sh scripts

[root@bf_test_qd_119 ~]# /U01/app/oracle/oraInventory/orainstRoot.sh

Changing permissions of /U01/app/oracle/oraInventory.

Adding read,write permissions for group.

Removing read,write,execute permissions for world.

Changing groupname of /U01/app/oracle/oraInventory to oinstall.

The execution of the script is complete.

[root@bf_test_qd_119 ~]# /U01/app/oracle/product/10.2.0/db_1/root.sh

这个clone很快，ok后，可以停原oracle实例及监听select distinct username from v$session; 查看应用是否停完

下面停掉所有监听

lsnrctl stop LISTENER

lsnrctl stop LISTENER1532

lsnrctl stop LISTENER1528

lsnrctl stop LISTENER1525

停数据库shutdown immediate //确定应用停完后，开始停数据库

开始拷贝数据文件scp -r /U01/app/oracle/product/10.2.0/dbs/* 1.1.1.1:/U01/app/oracle/product/10.2.0/dbs/

scp -r oradata/ 1.1.1.1:/U01/app/oracle/

cd /U01/app/oracle/admin/ldjbmdb && mkdir -p adump bdump cdump dpdump pfile udump utl_file

cd /U01/app/oracle && mkdir -p arch flash_recovery_area oraInventory

需要拷贝的包括如下：

1、控制文件

2、数据文件

3、参数文件spfile ? (环境一致)

4、密码文件

5、redo

没有首先检查这些文件的路径，然后再进行拷贝，这里我的目录基本都没有变，控制文件、数据文件、redo都 在oradata里，密码文件、参数文件都在dbs目录里。所以我只要拷贝两个目录就行。

然后就创建相应的目录，启动数据库startup mount;

alter database archivelog;

alter database open;

archive log list;

ALTER DATABASE FORCE LOGGING;

select log_mode,force_logging from v$database;

启监听

lsnrctl start LISTENER

lsnrctl start LISTENER1532

lsnrctl start LISTENER1528

lsnrctl start LISTENER1525

把数据库开启了archivelog(选择冷迁移的原因就在这里)

后面还有些步骤就是：

a.检查计划任务

b.防火墙

c.数据库自启动
