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.
