上周给自己的虚拟机11.2.0.4.5打.6的PSU没想到我在一个节点把之前opatch 备份的目录给删除了，结果就打不上补丁了。记住啊$GRID_HOME和$ORACLE_HOME下的.patch_storage目录可千万不能删除了，否则就无法打上补丁了。今天有时间，想折腾一下，查看了下，幸好2节点都没有 把目录删除，SCP过来，什么都没有修改，直接OPatch就成功了，特此纪念下。Metalink上的两篇文章我也拷贝下来了，就是关于.patch_storage的维护的，给需要的人看吧

要万一两个节点全删除了怎么办啊?官方给出了下面的方案：
- Restore complete .patch_storage directory from backed up ORACLE_HOME prior to the files missing .----还原
- Reinstall ORACLE_HOME .----重装ORACLE_HOME
- Clone the ORACLE_HOME from a identical environment .----找一个一模一样的环境克隆
好悲催，看来如果GRID_HOME和ORACLE_HOME在安装初期各给规划50G空间，真不算多。
我喜欢给每个节点手工打补丁，而不是opatch auto，可能是由于环境变量的问题，导致我使用opatch auto就没有成功过。
11.2.0.4.6 PSU手工打补丁请参照如下文档：
See My Oracle Support Document 1641136.1 for cases where opatch
auto cannot be used.
下面是我打补丁成功的截图：
