In accordance with the present invention, computer implemented methods and systems are provided that allow an application to automatically recover from software failures and attacks. Using one or more sensors, failures may be detected in the application. In response to detecting the failure, the portion of the application's code that caused the failure is isolated. Using the input vectors that caused the failure, information regarding the failure (e.g., the type of failure), a core dump file (e.g., stack trace), etc., an emulator-based vaccine that repairs the failure is constructed. In response to verifying that the vaccine repaired the failure, the application is automatically updated with the emulator-based vaccine without user intervention. Application community features that efficiently use the resources available in software monoculture is also provided. An application community may be defined that includes a plurality of devices and the application's code may be divided into smaller portions of code, which are assigned to each of the plurality of devices for monitoring. Each device also notifies the other devices of the failure.

A method, computer program product, and system for detecting and fencing off a failed entity instance so that failover time in the computing system is reduced. Upon detection of a failed entity, for example a failed process, a signal handler invokes an operating system interface to fence off the failed instance from modifying its persistent state, so that the entity may be re-instantiated prior to termination of the failed instance. This approach reduces failover time and eliminates split-brain problems without compromising access to the failed instance to obtain diagnostic information, core dumps, and the like.
