This section contains definitions of Autonomic Computing terms, which are utilized in this book.
The function of an autonomic manager that models complex situations.
Being accomplished without overt thought and action. An example is the human autonomic nervous system, which monitors and regulates temperature, pupil dilation, respiration, heart rate, digestion, etc.
An approach to self-managed computing systems with a minimum of human interference.
A part of an autonomic element that manages a managed element within the same autonomic element.
Definitions for standard situational event formats in autonomic computing architecture (also called logging). This notion is one of the core technologies of autonomic computing.
A domain is a collection of resources that have been explicitly or implicitly grouped together for management purposes.
A way to change the state of a managed element.
The function of an autonomic manager that is responsible for interpreting plans and interacting with element effectors to insure that the appropriate actions occur.
Definitions for standard methods to describe software deployment and installation. This notion is one of the core technologies of autonomic computing.
The common information that the monitor, analyze, plan, and execute functions require in order to work in a coordinated manner.
A graduated scale that expresses the level of maturity of autonomic computing, where level 1 is basic (completely manual), level 2 is managed, level 3 is predictive, level 4 is adaptive, and level 5 is completely autonomic.
A grid system architecture based on an integration of grid and Web services concepts and technologies.
The function of an autonomic manager that provides a way to coordinate interrelated actions over time.
A definite goal, course, or method of action to guide and determine future decisions. Policies are implemented or executed within a particular context. This is a set of behavioral constraints and preferences that influence decisions made by an autonomic manager. This notion of policy utilization is one of the core technologies of autonomic computing.
A method of managing system behavior or resources by setting policies that the system interprets.
An element setting itself up for operation.
An element repairing damage regarding its own integrity of operation.
An element directing and controlling itself. This is most often regarding self-configuring, self-optimizing, self-protecting, and self-healing operations.
An element tuning or improving its own performance.
A means to get information about a managed element.
Events that autonomic computing components report to the outside world. Situations vary in granularity and complexity, ranging from simple situations like the start of a component, to more complex situations like the failure of a disk subsystem.
