Autonomic computing overview

The Db2 autonomic computing environment is self-configuring, self-healing, self-optimizing, and self-protecting. By sensing and responding to situations that occur, autonomic computing shifts the burden of managing a computing environment from database administrators to technology.

Automatic features provides a high-level summary of the capabilities that comprise the Db2® autonomic computing environment; the following table provides a more detailed, categorized overview of the product's autonomic capabilities:
