^^^^^^^^^^^^^^^^^^^^
The concept of a "primary database" is just way out of
date. We support customers that require DR for 100+ databases.
In these terms you have to consider the ridiculous number
of DataGuard "circuits" to achieve such DR. The only way
to cover such a large number of databases' DR requirement is
to coalesce at the SAN level.
It all comes down to cost. If you can afford to care about DR,
you might care to afford reasonable communications
infrastructure.
But then, I'm sure there is some open source project of utter
brilliance percolating in the halls of some college dormitory
in outer Gangrenolia that will solve all such concerns.
