Abstract

A basic model for dynamic change management is proposed which permits changes to be specified declaratively at the configuration level in terms of structure only. Component nodes can be created and deleted and interconnections made and broken. Rules are provided which permit configuration management to identify the affected part of the system and to generate the required operational changes. These operations change the state of the selected component nodes to that suitable for reconfiguration, perform the particular structural changes, and provide the sequencing of the actions. A node responds by performing node-level actions to maintain local and intermode consistency. This model also provides a sound basis for the management of faults where failure of a component node is modeled as arbitrary deletion. The first steps toward unifying the management of dynamic change and fault recovery are described
