Abstract

See full text

Computer systems and methods of data processing are disclosed in which hierarchical levels of fault/event management are provided that intelligently monitor hardware and software and proactively take action in accordance with a defined fault policy. A fault policy based on a defined hierarchy ensures that for each particular type of failure the most appropriate action is taken. In one embodiment, a master Software Resiliency Manager (SRM) serves as the top hierarchical level fault/event manager, with one or more slave SRMs serving as the next hierarchical level fault/event manager. The software applications resident on each board can also include sub-processes (e.g., local resiliency managers or LRMs) that serve as the lowest hierarchical level fault/event managers.
