Upon the unavailability of a shard, failover is initiated automatically to another copy of the data. Each shard may run a different release of the Oracle Database as long as the application is backward compatible with the oldest running version – making it simple to maintain availability of an application while performing database maintenance.
- Global data distribution for data proximity – to…
