Hi Art,

I hope your remarks about HDR and checkpoints are valid only if DRINTER=
VAL
is
set to -1 (synchronous update) ? Otherwise I can't imagine how HDR can =
be
used
for a large high performance production system? And what happens if the=

secondary or the network connections become unavailable for some time?

Regards,
Andreas Kutsche
