- We did this thing several times with a HP/Oracle environment. Our unix
guy
needed some hotline support the first time, since that it works
without probs.
- We are dumping the data directly on a tape (via a named pipe I think).
Takes
about 35 hours per load/reload for 27 gig.
- Most people will probably have faster tape backups than we have. If
you have
enough disk space that should be MUCH faster than this.

Every program has at least one bug and can be shortened by at least one
instruction -- from which, by induction, one can deduce that every
program can be reduced to one instruction which doesn't work.
