Recently installed 10.2.0.1 upgraded to 10.2.0.4 on Red hat 4.8 x86. Attempted to load patch 9119284_10204 and opatch failed. "Patch id is null". "Opatch failed with error code 73".
Ran opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /Patches/10.2.0.4.3/
Error "Unable to create Patch Object"
Exception Occurred: Patch ID is null.
I swear I follwed the README to a note.
