What does EJB or BEA WebLogic Server provide to work with database failure? If I have two databases (exact replicas that are always in synch) and they are on two different boxes, how can I configure EJBs or specifically BEA WLS to use the stand-by database when the primary database is down? In a perfect world, I would like to use the connection pool offered by BEA WLS, and if the datasource is unavailable, I would like WLS to seemlessly move to the back-up datasource. Is this possible? If do how? If not, what alternatives are there. Any feedback is greatly appreciated.

The newer WLS has a feature called multipools that does what you want. Check the BEA documentation for more on multipools.
