Yup - ftp, rcp, rsync - whatever you like, as long as the host running
orca gets access to the datafiles.

orca will look for them under the --prefix directory by default (see
the 'find_files' definitions in the orcallator.cfg file) but you need
to arrange for the data files to be copied there.

Have a look at the script that starts se at boot time
(/etc/init.d/percol)

Near the top you'll see a line of the form

OUTDIR=/var/adm/sa/perf; export OUTDIR

OUTDIR is the directory where the data files will appear (and from
which you should copy them to the appropriate directory on the host
running orca).
