HDR doesn't take care of failing over IP addresses, does it?
What about automatically switching from backup to primary when
one system goes down? (without rolling your own scripts to
do the detection / failover).

DB2 can do "HA" without the 3rd party HA products using log
shipping. Granted, log shipping is primitive in comparison
to HDR, but I think that it is closer in functionality than
HACMP/MSCS/etc.
