原因： 在使用root用户进行opatch auto 打补丁的时候，需要su - grid -c ' ...'去进行补丁安装，故执行pre 的身份仍是root，身份不正确。
可以用如下命令来验证： 'su <db-user> -c "echo $USER" ' ，例如
[root@rac1 ~]# su - grid -c "echo $USER"
root
解决方法：
以root用户执行下面命令安装PSU：
给GI安装PSU：
export USER=grid
/u01/app/11.2.0/grid/OPatch/opatch auto /soft/28813878 -oh /u01/app/11.2.0/grid
给Database安装PSU:
export USER=oracle
/u01/app/oracle/product/11.2.0/db_1/OPatch/opatch auto /soft/28813878 -oh /u01/app/oracle/product/11.2.0/db_1
