Can you try your command sequence on a small schema export and import? Make sure that works first. I checked my own note: http://yong321.freeshell.org/oranotes/ImpExpThruPipe.txt I did not use one single pipe to store multiple, split, partial files as you do, although I think your method should also work. I had bad luck with compress when I did a big export job. Try gzip instead. If you export and import across hosts, Joel Patterson's rsh approach works great. See "Export/import across hosts" in my note. Yong Huang --- On Fri, 8/7/09, A Joshi <ajoshi977@xxxxxxxxx> wrote: > Yong, > Thanks. My sh did have a rm -rf comp_pipe > in the beginning.
