5 Transparent Application Continuity

This topic provides the information about the transparent application continuity.

Transparent Application Continuity (TAC) is a high‑availability capability in Oracle Database that ensures uninterrupted workload processing during both planned maintenance activities and unexpected disruptions at the database tier. By seamlessly capturing and replaying in‑flight requests, TAC enables applications to continue running without visible downtime or user errors. TAC is compatible with established applications as well as new deployments, providing robust protection across a broad range of application stacks — all without requiring any changes to application code.
