在前面的几篇文章中，分别介绍了如何使用expdp，传输表空间，rman异机备份以及maa等方式将单实例数据库迁移至rac环境，服务器空间，本文将介绍如何使用dbca工具创建数据库模板，进而实现单实例数据库到rac的迁移，这样做的优势是单实例数据库上的所有用户，表空间，索引，视图，触发器，存储过程，香港空间，包等等都可以完美的迁移到rac环境上，但要求单实例数据库的版本和rac的版本要一致，是否可以跨平台，尚未测试，本文在单实例数据库rhel6 64位，rac为centos 4.8 64位，数据库版本均为10.2.0.5
一：在单实例数据库上创建表空间和用户，建测试表
二：在单实例数据库上使用DBCA工具创建带数据文件的模板
三：将产生的模板文件scp到rac数据库实例1上，复制到rac1的相应目录下
四：在rac数据库实例1上使用dbca工具选择模板建库
五：验证结果

Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
