If your Oracle E-Business Suite (Oracle EBS) online patching process failed only at the adop phase=prepare phase, then you can abort the online patching process by running the following commands.
echo $FILE_EDITION (Must show run)
adop phase=cleanup cleanup_mode=full
The additional adop phase=fs_clone is required only if it failed at the actual patch apply phase i.e adop phase=apply. Otherwise fs_clone is not required.
