Information in this document applies to any platform.


From the definition of Application Continuity (AC), the AC replays support Data Guard environments, and it replays the uncommitted transactions in the standby when primary fails.

Application is connected to the Primary Database. Application executes transactions and commits the data. However, the committed data does not reach the standby database due to network latency.
In such scenario, if a failover to the standby database from the primary database is performed, will the replay drivers continue to replay the transaction that was committed but not replicated to the standby site?
What level of protection does Application continuity gives in such scenario?
