And DUL doesn't need a running instance to do it's job.  All it needs
are as much data files as you got.

Hi!

Good point, but there are few issues. Unloading data with SQL is slower than
doing it directly. Yes, direct export is very fast, but it doesn't have the
flexibility DUL does - DUL is built do survive any corruptions in data,
while your export just may fail or server process crashes, DUL just keeps
going & tries to extract as much as possible.

Tanel.

an "online" DUL. If I remember right it's called something like SQL.
