OPatch cannot find a valid oraInst.loc file to locate Central Inventory

环境概述：

操作系统：AIX 6.1
Oracle软件版本：11.2.0.3
OPatch version：11.2.0.3.21（使用的是临时补丁）

故障现象

OPatch cannot find a valid oraInst.loc file to locate Central Inventory.  
  
OPatch failed with error code 104  

该问题是由于opatch找不到oraInst.loc文件所导致，在命令后指名具体路径即可

解决方法如下：

oracle@pwr750e2:/oracle/product/11.2.0.3/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./ -invPtrLoc /etc/oraInst.loc
