出于研究或者测试的目的我们可能已经在平台上安装了11gR2的Grid Infrastructure和RAC Database，因为GI部署的特殊性我们不能直接删除CRS_HOME和一些列脚本的方法来卸载GI和RAC Database软件，所幸在11gR2中Oracle提供了卸载软件的新特性:Deinstall，通过执行Deinstall脚本可以方便地删除Oracle软件产品在系统上的各类配置文件。
具体的卸载步骤如下：
1. 将平台上现有的数据库迁移走或者物理、逻辑地备份，如果该数据库已经没有任何价值的话使用DBCA删除该数据库及相关服务。
以oracle用户登录系统启动DBCA界面，并选择RAC database:
[oracle@vrh2 ~]$ dbca
在step 1 of 2 :operations上选择删除数据库 delete a Database
在 step 2 of 2 : List of cluster databases上选择所要删除的数据库
逐一删除Cluster环境中所有的Database
2.
使用oracle用户登录
任意节点并执行$ORACLE_HOME/deinstall目录下的deinstall脚本

以上deinstall脚本会删除所有节点上的$ORACLE_HOME下的RDBMS软件，并从central inventory中将已经卸载的RDBMS软件注销，注意这种操作是不可逆的！
3.
使用root用户登录在所有节点上注意运行"$ORA_CRS_HOME/crs/install/rootcrs.pl -verbose -deconfig -force"的命令，注意在最后一个节点不要运行该命令。举例来说如果你有2个节点的话，就只要在一个节点上运行上述命令即可：
[root@vrh1 ~]# $ORA_CRS_HOME/crs/install/rootcrs.pl -verbose -deconfig -force

############# ORACLE DEINSTALL & DECONFIG TOOL END #############
deintall运行完成后会提示让你在必要的节点上运行"rm -rf /etc/oraInst.loc"和"rm -rf /opt/ORCLfmap"，照做即可。
以上脚本运行完成后各节点上的GI已被删除，且/etc/inittab文件已还原为非GI版，/etc/init.d下的CRS相关脚本也已相应删除。
