5.oracle打optch报错:Inventory load failed... OPatch cannot load inventory for the given Oracle Home

昨天在安装12c补丁时：当执行opatch lspatches查询当前节点的补丁包时，发现报这种错误：

这里也可以用opatch lsinv命令(该命令查看的结果显示的更加详细一些)

Inventory load failed... OPatch cannot load inventory for the given Oracle Home.

这里从mos文档中查看的原因是找不到路径，因为解决方法是：

sh $ORACLE_HOME/oui/bin/attachHome.sh

Starting Oracle Universal Installer...

Checking swap space: must be greater than 500 MB.   Actual 32698 MB    Passed
The inventory pointer is located at /etc/oraInst.loc
'AttachHome' was successful.

然后再用opatch lspatches 或者opatch lsinv进行查看就正常了。。。
