Oracle Application Continuity

Application Continuity

Improving Continuous Availability

Application Continuity

Application Continuity (AC) is a new feature available with the Oracle Real Application Clusters (RAC), Oracle RAC One Node and Oracle Active Data Guard options that masks outages from end users and applications by recovering the in-flight database sessions following recoverable outages.

Transaction Guard

Transaction Guard is a reliable protocol and tool available with the Oracle Database 12c that returns the outcome of the last in-flight transaction after outages that make the database session unavailable. It is used by Application Continuity to ensure that an in-flight transaction is committed successfully, no more than once. It can also be used directly by applications to return a known outcome to the end users.
