Phoenix Project: Fault-Tolerant Applications

Roger Barga and David Lomet


After a system crash, databases recover to the last committed transaction, but applications usually either crash or cannot continue. The Phoenix purpose is to enable application state to persist across system crashes, transparent to the application program. This simplifies application programming, reduces operational costs, masks failures from users, and increases application availability, which is critical in many scenarios, e.g., e-commerce. Within the Phoenix project, we have explored how to provide application recovery efficiently and transparently via redo logging. This paper describes the conceptual framework for the Phoenix project, and the software infrastructure that we are building.
