| This section contains definitions of Autonomic Computing terms, which are utilized in this book. - Analyze
-
The function of an autonomic manager that models complex situations. -
- Autonomic
-
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. -
- Autonomic computing
-
An approach to self-managed computing systems with a minimum of human interference. -
- Autonomic manager
-
A part of an autonomic element that manages a managed element within the same autonomic element. -
- Data collection
-
Definitions for standard situational event formats in autonomic computing architecture (also called logging). This notion is one of the core technologies of autonomic computing. -
- Domain
-
A domain is a collection of resources that have been explicitly or implicitly grouped together for management purposes. -
- Effector
-
A way to change the state of a managed element. -
- Execute
-
The function of an autonomic manager that is responsible for interpreting plans and interacting with element effectors to insure that the appropriate actions occur. -
- Install (Installation)
-
Definitions for standard methods to describe software deployment and installation. This notion is one of the core technologies of autonomic computing. -
- Knowledge
-
The common information that the monitor, analyze, plan, and execute functions require in order to work in a coordinated manner. -
- Maturity Index
-
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. -
- OGSA (Open Grid Services Architecture)
-
A grid system architecture based on an integration of grid and Web services concepts and technologies. -
- Plan
-
The function of an autonomic manager that provides a way to coordinate interrelated actions over time. -
- Policy
-
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. -
- Policy-based management
-
A method of managing system behavior or resources by setting policies that the system interprets. -
- Self-configuring
-
An element setting itself up for operation. -
- Self-healing
-
An element repairing damage regarding its own integrity of operation. -
- Self-managing
-
An element directing and controlling itself. This is most often regarding self-configuring, self-optimizing, self-protecting, and self-healing operations. -
- Self-optimizing
-
An element tuning or improving its own performance. -
- Self-protecting
-
An element maintaining its own integrity of operation. -
- Sensor
-
A means to get information about a managed element. -
- Situations
-
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. -
