1. From the above error log file can find the error occurs when try to look for the actions.xml and inventory.xml of Patch 9209238.

2. Then find and check the opatch log file when applying the Patch 9209238 before.

3. So can find that at that time when applying Patch 9209238, the opatch version is 11.1.0.6.8, but now when using opatch lsinventory, the opatch version is 11.1.0.6.3.

So the cause is that the current opatch version is lower than the version which was used to apply the Patch 9209238 before.

Solution
Please use the latest version of opatch.

The latest version of opatch can be downloaded and installed from patch 6880880. To help you to obtain the correct download for your platform. and RDBMS release version.
