MSSQL vs Oracle on patching the binary before installing them

 Slipstream in MSSQL:  Apply CU on SQL binary even before setting up the instance

cd <Downloaded SQL binary path>\

setup.exe /Action=Upgrade /UpdateEnabled=True /UpdateSource="<path of downloaded CU>"

You do the same in oracle using..

./runInstaller -applyRU <RUBinary> -applyOneOffs <oneoff1>,<oneoff2> etc...

All these helps in applying the fix while an upgrade is attempted. So you dont need any workarounds :)
