使用oracle 11.2.0.2提供的deinstall工具删除oracle软件

Oracle11g R2的补丁集11.2.0.2出来了一段时间，由于GIRD INFRA升级需要时Out of place方式升级，这会导致在服务器上面存在两个GRID_HOME一个是11.2.0.1的一个是11.2.0.2的，如何删除老版本的GRID_HOME呢？
oracle在11.2.0.2版本的补丁包中提供了一个deinstall的工具，专门用来卸载oracle的软件，包括GRID INFRA和RAC软件都可以。下面是删除的过程：

1、先解压缩包p10098816_112020_Linux-x86-64_7of7到/grid目录下面

2、不能用root用户运行deinstall，使用root运行结果如下：

[root@node1-11gr2-rac grid]# /grid/deinstall/deinstall -home /grid/app/11.2.0
You must not be logged in as root to run /grid/deinstall/deinstall.
Log in as Oracle user and rerun /grid/deinstall/deinstall.

3、使用GRID_HOME的owner grid用户执行删除操作：

grid用户删除GRID_HOME,2个节点都删除
[grid@node1-11gr2-rac ~]$ /grid/deinstall/deinstall -home /grid/app/11.2.0

自此，GIRD_HOME删除成功。当然使用这个deinstall也可以删除RAC软件，大致过程如下：

[oracle@node1-11gr2-rac home]$ cd /u01/app/11.2.0/
[oracle@node1-11gr2-rac 11.2.0]$ ls
oracle oracle.backup

oracle是11.2.0.2的oracle_home
oracle.backupo是11.2.0.1的oracle_home
[oracle@node1-11gr2-rac 11.2.0]$ du -s -m *
