STAC: software tuning panels for autonomic control

One aspect of autonomic computing is the ability to identify, separate and automatically tune parameters related to performance, security, robustness and other properties of a software system. Often the response to events affecting these properties consists of adjusting tuneable system parameters such as table sizes, timeout limits, restart checks and so on. In many ways these tuneable parameters correspond to the switches and potentiometers on the control panel of many hardware devices. While modern software systems designed for autonomic control may make these parameters easily accessible, in legacy systems they are often scattered or deeply hidden in the software source. In this paper we introduce Software Tuning Panels for Autonomic Control (STAC), a system for automatically re-architecting legacy software systems to facilitate autonomic control. STAC works to isolate tuneable system parameters into one visible area of a system, producing a resulting architecture that can be used ...
