Towards Unifying Fault And Change Management

A basic model for dynamic change management has been 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 from this specification. 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 internodes consistency.
