关于RAC下如何卸载数据库

配置RAC数据库运行平台：

数据库版本： 10.2.0.1 ；   操作系统版本： 2.6.9-55.0.0.0.2.ELhugemem； 数据库的ＣＲＳ安装在/u01/oracle/product/10.2.0/crs_1目录下 ；我把database 安装在 /u01/oracle/product/10.2.0/db_1目录下。ITPUB个人空间~SDY&cJ
u

出现的问题：

在配置RAC的时候，数据库软件安装完毕，创建数据库的时候，出现中断。

解决办法：

1、尝试将数据库软件和数据库删除掉（其实傻了，直接把数据库删掉重建可以了）。当时没想太多。。。。   这个是我失误的一个地方。

2、手动删除/u01/oracle/product/10.2.0/db_1目录下所有文件，重新运行./runInstaller，结果在检测环境的时候，出现严重错误。

3、我尝试将数据库软件安装在另外一个目录下oradb10g_home2，默认是oradb10g_home1。结果还是没成功。

4、最后，删除操作系统，重新配置（这样多可以熟悉熟悉配置过程）

随后有一个网友给我提供了一个卸载的办法：虽然没有测试过，但是觉得有一定道理，收藏日后可是试试。
