Issue

Unable to apply part of FMW Common server patch 9905685 under directory sa

Patch 9905685 comes with two directories - 'oui' and 'sa'.

I could successfully apply the patch under 'oui' directory. But following error was thrown when applying the patch under 'sa' directory:

Solution
SA is for a 'Standalone Application' installation of FMW. You only need to apply the 'oui' version of the patch. So you can safely ignore it and proceed ahead with your other remaining patch applications.
