To use RFA, each logon user would need to remote hello to the node with
the real database, and in case you've never beat on RFA/Remote-DBA much,
I can tell you emphatically that it's SLOOOOOOW. In a previous life, I did
a LOT of experimenting with remote DBA, and though it worked, the overhead
is VERY high (and the numerous remote logons will tax the user-license of
your 3000 holding the real database if it's not an unlimited license machine).

FWIW, the most common methods of RDBA are:
1) Users explicitly (or via a hidden UDC) issue DSLINE/REMOTE HELLOs to the
   remote system, then file equate the database to the remote system,
  or
2) you create an RDBA file - looks like an Image root file but has the DSLINE
   and remote hello info encoded within the (priv) file. When someone DBOpens
   the database, Image does the DSLINE/REMOTE HELLO stuff for them. A bit
   more secure perhaps (as the users can't see the remote logon info) but
   still just as slow.

To do RDBA and be remotely responsive (i.e. to support real-world response
times) you really need to look at something like Quest's NetBase.
