跨平台迁移数据库windows-Linux

将10.10.1.127服务器的数据库ORCL(WINDOWS)迁移到VM 10.10.10.168LINUX平台

操作系统：Windows server 2008r2 64bit

CentOS  Linux  6.5  64bit

ORACLE软件:11.2.0.3.0

目录：

1. 1.     在源数据库（Windows数据库orcl准备迁移）

2. 用 RMAN 生成迁移文件
3. 修改对应的转换文件
4. 修改对应的 INIT 文件
5. 在目标 LINUX（linux 数据库 orcl）在用 DBCA 创建数据库
6. 删除文件，复制文件
7. 升级

1.在源数据库（Windows数据库orcl准备迁移）

1，检查源库的控制文件，数据文件，日志文件，临时文件，参数文件等！

查看可以转换的平台

在目标端执行，捕获目标库平台

运行检查包

查看归档模式

关闭数据库，将数据库启动到只读模式！

2. 用
RMAN 生成迁移文件

对源数据文件进行转换，并生成升级脚本

查看生成的数据文件和升级脚本

3. 修改对应的转换文件

更改TRANS.SQL的路劲，对应LINUX平台的路劲

Linux路劲：

4. 修改对应的
INIT 文件

 

更改参数文件的相关参数路劲

 

5. 在目标
LINUX（linux 数据库 orcl）在用 DBCA 创建数据库

 

用DBCA创建ORCL数据库，并将数据文件，参数文件，日志文件和控制文件删除，再把转换好的相应文件复制到linux相应的路劲

6. 删除文件，复制文件

删除复制后文件后，执行TRANS.SQL脚本

 

7，升级

执行升级脚本

 

遇到错误，提示将数据库启动到升级模式，再执行UTLIRP.SQL脚本

跑完脚本，提示正常关闭和启动数据库，脚本已经执行，可以不用执行

 

检查数据库的状态和文件

验证数据的有效性
