How to configure Oracle traffic director for full site failover to have high availability? I have two server systems, each server having both Apache Tomcat server (deployed web app) and Oracle 11g database server. The database on the two servers is synchronised by Oracle Data Guard for high availibility. Tomcat web server is running individually on each server system with no load balancing. One server acts as primary server and other server acts as redundant server.
Usually for any failure on primary server, I have to manually change the IP/Domain name to access the other server.
I have came across Oracle Traffic Director which may solve my isssue to switch any client request to redundant server in case of failure of primary server. Since I am new to Oracle Traffic Director, can anyone guide me to configure OTD for full site failover?
For a true HA architecture, HTTP traffic must be balanced with a front-end load balancer on a separate host. See here for a list of open source balancers (any of which would be simpler and cheaper to implement than OTD):

Oracle DB connections should be configured for high availability failover as described here (use the architecture that best fits your technology stack):

An example of how to implement tomcat's native clustering to compliment the load balancing can be found here on my blog site:
