I checked the application schema and all lobs are created with
CACHE=NO and IN_ROW=YES.
Some of them have LOGGING turned on, some not.
I also noticed that the version of 8i is 8.1.7.0.0, so without any
patch set installed. I will contact the application vendor to see if
they have an update or if I can upgrade myself.
