A Stretch Cluster extends the traditional active-active redundancy model for High Availability, where members of an Oracle Fusion Middleware cluster are distributed over two or more geographically separated sites. Typically the sites are 10's of miles apart with low network latency between the sites. This then allows for both High Availability (loss of a process, loss of a node) and Disaster Recovery (loss of a data center/site).
This would be typically implemented in a Campus Area Network/Metropolitan Area Network (CAN/MAN) network, although in some cases it has been known to be implemented across the globe in a Wide Area Network (WAN) setup.
Is it possible to use Stretch cluster deployment for Oracle Application Server 10g?
