Transaction Support for Log-Based Middleware Server Recovery

Abstract— We have developed log-based recovery for middleware servers that access back-end transaction systems (DBMSs). Transactional consistency is provided between in-memory state stored in middleware servers and persistent state stored in transaction systems. A new logging method called results logging is exploited to ensure coordinated recovery of in-memory state with persistent database state. Results logging incurs low logging overhead for middleware servers and requires little or no modification to existing transaction systems. This makes our approach a practical coordinated recovery technique.
