I'll try the crosscheck. I'm not connecting to the catalog so I wouldn't need to update there but maybe crosscheck so the control file is aware.
VNK, I typed up a shortened version of my duplicate script but here is more:
connect target username@sid
connect auxiliary /
CONFIGURE CHANNEL DEVICE TYPE disk CLEAR;
CONFIGURE DEFAULT DEVICE TYPE TO disk;
CONFIGURE DEVICE TYPE disk PARALLELISM 3;
@set decryption identified by "password";
set until time "to_date('05-mar-2010 09:30:00' , 'dd-mon-yyyy hh24:mi:ss');
duplicate target database to "SBX'\:
group 1 ...
group 2 ...
group 3 ...
All of this worked so, I am thinking what Mr. Burleson said about the crosscheck makes sense.
Thanks a bunch, appreciate the replies!
