With these sizes, I usually only export the schema structures using
rows=n and tables are transferred over dblinks in direct mode (there is no
direct mode import possibility until 10g, and even then it's done using data
pump, Oracle's new exp/imp toolset)
Also I build indexes only after import, in nologging and parallel
mode.

Subject: Re: IMP using the same DMP
file
On the subject of export/import, has anyone exported a 1 TB db
and imported it into another db? The largest I have done is 300gb w/out
problems.

You can import the same file into two instances
simultaneously, because
"imp" doesn't lock the import file, unless the
import file was produced
by simultaneous export into the same file from two
different instances,
in which case you have something what is
scientifically known as
"monster mess" and is really appropriate for the
Halloween time.
