Oracle Application Continuity enables database requests to automatically replay transactional or non-transactional operations in a non-disruptive and rapid manner in the event of a severed database session, which results in a recoverable error. Application Continuity improves end-user experience by masking planned and unplanned related errors. Applications can be developed without complex logic to handle exceptions, while automatically replaying database operations upon a recoverable error.

Without Application Continuity, it is almost impossible to mask outages in a safe and reliable manner. Common issues encountered include:

• The client state remains at present time, with entered data, returned data, and variables cached, while the database state changes are lost.

• If a transaction commit has occurred, the commit message is not durable. Moreover, checking a lost request does not guarantee that it will not commit after being checked.

• Non-transactional database session state is lost.

• If the request can continue, the database and the client session must be synchronized.

Application Continuity is available with Oracle Database Enterprise Edition with a Real Application Clusters or Active Data Guard option license.
