Effecting Runtime Reconfiguration in Managed Execution Environments

TL;DR: Kheiron is introduced, a framework for facilitating adaptations in running programs in a variety of execution environments without requiring the re-design of the application.

TL;DR: In this paper, the authors present a system model that will explicitly define graceful degradation as a system property, and measure how well a system gracefully degrades in the presence of multiple combinations of component failures.

TL;DR: A number of case studies are described to motivate and discuss the significance of application-level utility, the statistical synthesis method is illustrated, and the framework for instrumentation, monitoring, and utility function embedding/evaluation is presented.

TL;DR: This tutorial shows how to use AOP to implement crosscutting conerns in a concise modular way and includes a description of their underlying model, in terms of which a wide range of AOP languages can be understood.

TL;DR: AspectJ as mentioned in this paper is a simple and practical aspect-oriented extension to Java with just a few new constructs, AspectJ provides support for modular implementation of a range of crosscutting concerns.

TL;DR: The rainbow framework provides reusable infrastructure together with mechanisms for specializing that infrastructure to the needs of specific systems, and lets the developer of self-adaptation capabilities choose what aspects of the system to model and monitor, what conditions should trigger adaptation, and how to adapt the system.

TL;DR: This work describes a formal framework for studying online software version change, gives a general definition of validity of an online change, shows that it is in general undecidable and develops sufficient conditions for ensuring validity for a procedural language.
