在10g中要卸载CRS是件非常繁琐的事。到了11g，oracle提供了卸载工具deinstall，用这个工具可以卸载的非常干净。这个工具默认放在oracle用户下的$ORACLE_HOME/deinstall/deinstall,grid用户下的$ORACLE_HOME/deinstall/deinstall 。google了下，发现只需要执行这个工具一次就可以了。但
是在自己的实际测试当中分别oracle用户和grid用户各执行了一次才卸载完成。猜想可能只需要grid用户执行一次deinstall就可以了，这个以后再测试。
测试环境
redhat 5.8 64bit oracle 11.2.0.1 rac+asm
以下只需要在一个节点执行deinstall即可
1.oracle用户执行deinstall，卸载oracle database 和oracle软件
deinstall 工具只需要在rac中的一个节点执行就可以了，执行节结束后，oracle database和oracle软件卸载完成，集群没有卸载
#切换到oracle用户执行deinstall

在执行完最后一步，才算真正的完成了oracle 11g rac 的卸载。
总结：
1.虽然用两步才完成rac的卸载，但是也从中发现，deinstall也可以单独卸载oracle软件和database
2.deinstall一步完成rac的卸载，待测试。
oracle 11gr2 deinstall卸载oracle和grid
