4.3 Tivoli Linux systems administration
Tivoli is a complete IBM framework that assists administrators in managing a
complex IT environment. It performs distributed backups by applying backup
policies, installs software and updates, and controls workstations and servers
remotely. Using all the information that it gathers from the different systems,
Tivoli provides views of the company’s IT infrastructure to help management and
administrators to take decisions. In short, Tivoli provides a wide range of
capabilities that cover performance, availability, provisioning, configuration,
security, and storage management.
Linux is a supported managed environment for most of the Tivoli applications. To
describe all of the capabilities to manage Linux clients using Tivoli would require
a redbook of its own. Visit the Tivoli pages at the following Web site for more
information about the Tivoli suite of products:

more than by technical ones.
The following sections describe some of the facilities that are available to assist
administrators in keeping Linux clients (and servers) up to date.
