                    The logging subsystem is required for recovery purposes, but
                    its usage also means your application may require a
                    little more administrative effort than it does when logging
                    is not in use. See <a class="xref" href="filemanagement.html" title="Chapter 5. Managing DB Files">Managing DB Files</a> for more information.
