Subject: Re: event "Network file transfer"
Ignore my previous comment.
I've done some searching and the "new event" was something about "vector data
to/from client", not about file transfer

It is challenging to find information because search keywords like "oracle
event network file transfer" returns a lot of unrelated stuff.
Does anyone have any links or information on this event and what it represents?
Thanks!
