This is not how TIBCO RV works.  You need to connect to the RV daemon
(which can be auto-started on your local host) but you do not need to
pre-register anything if you're using the normal "reliable" QoS. 
There is no direct communication between subscribers and the
publisher.  If a subscriber (or really its RV daemon) detects a gap in
sequence, it will request a retransmission automatically and, if the
message is still in-core on the sender side, the sending RVD will
resend it.  I'd call this NAK-based processing and it is overall quite
effective.

With their Certified Messaging protocol, however, each subscriber
registers with the publisher and must ACK each message.
