In case you are trying to apply the CPUJan2016 against an Oracle WebLogic Server 12.1.2 you may run into following error:
Verifying the update... [ Error during Update inventory for apply Phase]. Detail: There are 1 copy files under ORACLE_HOME that are not patched. Files check failed: Some files under ORACLE_HOME are not patched. Please see logfile for details. [ Error during Update inventory for apply Phase]. Detail: OPatch failed: ApplySession failed in system modification phase... Verification of patch failed: Files are not updated completely.
The problem occurs under following conditions:
- OPatch 22.214.171.124.0
- JDK 1.7
- CPU Patch Number: 21984577
The solution is relatively simple :-) use instead of opatch apply the command opatch napply.
Happy Patching ...
