| JAGR: An Autonomous Self-Recovering Application Server (2007) | |||||||||||||||
Abstract | |||||||||||||||
| This paper demonstrates that the dependability of generic, evolving J2EE applications can be enhanced through a combination of a few recovery-oriented techniques. Our goal is to reduce downtime by automatically and efficiently recovering from a broad class of transient software failures without having to modify applications. We describe here the integration of three new techniques into JBoss, an open-source J2EE application server. The resulting system is JAGR---JBoss with Application-Generic Recovery---a self-recovering execution platform. JAGR combines application-generic failure-path inference (AFPI), path-based failure detection, and microreboots. AFPI uses controlled fault injection and observation to infer paths that faults follow through a J2EE | |||||||||||||||
