IMHO, dbexport / dbimport works the best. You *can* export to tape, but
I would use disk, if you have enough file space.
Pointers:
-- make sure your ulimit is set high enough to handle your big-table
data files;
-- be aware that dbexport requires a DB *exclusive* lock (there can be
no other users in the DB);
-- after the dbexport, but before the dbimport, you may want to edit
the <databasename>.sql file,
changing first/next extent sizes;
-- depending on your system, this *may* take quite a while; you may
want to do a test
unload/load of some of your larger tables to get an idea of the time
required
