Oracle 11g之后提供了卸载grid和database的脚本，可以卸载的比较干净，不需要手动删除crs
##########如果要卸载RAC，需要先使用dbca删除数据库，在执行下面的操作###############
1.root用户进入到grid的ORACLE_HOME(在最后一个节点以外的所有节点执行，如果只有两个节点的RAC那么只在主节点上执行即可)
|
说明：（如果没有从官网上下载） 1.从oracle官方网站上下载的deinstall工具 11GR2有7个下载包，deinstall放在第7个下载包，如11.2.0.2的下载包为p10098816_112020_AIX64-5L_7of7.zip 2.解压到本地目录,并执行deinstall 需要输入$ORACLE_HOME bash-3.00$ ./deinstall -home /oracle/grid/product/11.2.0/grid Location of logs /ora11g/server_install/deinstall/./logs/ |

执行完成上面的两个命令后，oracle的数据库软件也就删除了，就可以重新执行root.sh脚本了~~~
如果使用了asm磁盘，需要先清理asm磁盘，因为尝试了一次安装，你的ASM磁盘就被标记为used，不能再作为候选磁盘，要想再次使用，需要执行下面的操作
a.使用dd命令覆盖分区的头部信息
dd if=/dev/zero of=/dev/sdb1 bs=1024 count=100 dd if=/dev/zero of=/dev/sdc1 bs=1024 count=100 dd if=/dev/zero of=/dev/sdd1 bs=1024 count=100 dd if=/dev/zero of=/dev/sde1 bs=1024 count=100
b.删除并重建asm磁盘
/etc/init.d/oracleasm deletedisk DISK1 /dev/sdb1 /etc/init.d/oracleasm createdisk DISK1 /dev/sdb1 /etc/init.d/oracleasm deletedisk DISK2 /dev/sdc1 /etc/init.d/oracleasm createdisk DISK2 /dev/sdc1 /etc/init.d/oracleasm deletedisk DISK3 /dev/sdd1 /etc/init.d/oracleasm createdisk DISK3 /dev/sdd1 /etc/init.d/oracleasm deletedisk DISK4 /dev/sde1 /etc/init.d/oracleasm createdisk DISK4 /dev/sde1
执行完上面的命令后，asm磁盘就可以用了
如果要彻底卸载Grid Infrastructure软件，执行下面的命令
2.grid用户执行deinstall进行卸载（两个节点）
