I am testing the duplicate command now. I don't think you need password
file on server A, but you do need a password file on server C. To my
understand, you do need 3 connections to make it work. Even you want
duplicate days old copy. I think rman somehow needs info from control
file on server A. For example, once I reset the database on target. I
can't duplicate it with any backupset any more. Anyway, I am still
learning and testing it. probably not know better than you do.

Hello listers,
We have a instance on server A, a RMAN recovery catalogue on server B
and a 3rd server C where we want to create a copy of the live database
with a new sid.
This is on Oracle 8.1.7
The RMAN duplicate command seems to be the one to use but there is one
hing I cannot understand.
All the documentation (and I have RTFM until my head hurts) suggests
that the run script needs to make 3 connections (target - server A,
rcat - server B and new instance server C).
I do not know why we need to connect to the target sid (server A) at
all. We don't want a synchronised duplicate at all but from midnight
last night (or 3 days ago is fine). Therefore the rcat should all the
information it requires. Furthermore we don't have
remote_login_passwordfile created on server A and we don't really want
to .
As part of the testing we tried setting the dbid to the name of the
instance we want but it still seems to expect the connection to
server A.
Anyone have any experience in this area that could help me.
