I cant think of any way to do reliable HA (as opposed to DR) across the
country. You could in theory do an active-passive cluster, that would
technically be HA, but really its more DR as you active that the passive
side when the active side fails.

I got this directive from my management. COB is our
terminology for Disaster Recovery.
As part of the strategic course we are taking – we are looking at
eliminating COB and go to a fully HA model (not only within DC, but also
leveraging other DC) as such we want
to look at tools/methods, etc… around DB DC replication.
Thoughts on best tools out there today to accomplish this (speed is a key
component)
Other than Dataguard, which does require another instance,
does anyone know of any other solutions?
