The web blog strives to be a comprehensive guide to SCCD, TADDM, SERVICE NOW and MAXIMO tools. This is a personal site maintained solely by me. I intend to update it regularly.For live updates please follow us on.



Tivoli Application Dependency Discovery Manager (TADDM) is an IBM tool which delivers automated discovery and configuration tracking capabilities to build application maps that provide real-time visibility into application complexity.


By using taddm we can discover how one's configuration items (CI's) are configured and changing over time. By capturing the configuration of each CI, tracking changes to it and providing analytics to report on the history of these configuration changes over time

What Problems does TADDM solve?

Today’s composite applications (e.g. J2EE, .NET, etc.) consist of large numbers of infrastructure components with run-time dependencies. Without visibility into these applications and their supporting infrastructure, it is difficult to effectively deliver and manage mission critical business services. This problem has become even more acute with the accelerating rate of change in today’s application infrastructure.
How does TADDM automatically discover the application infrastructure?

Upon discovery initiation, TADDM’s discovery engine proceeds thru a multi-step process:

•The discovery engine uses standard protocols such as SNMP to inspect the defined discovery scope to identify the IP nodes (address) of all installed devices.
•For each valid IP node in the set, TADDM’s discovery engine launches a discovery sensor.
•The discovery sensors discover and categorize the component type by matching it to the appropriate signatures in the Data Center Reference Model.
•The discovery sensors then query the component for its configurations and dependencies.
•The discovery process is iterative; each discovery sensor run can spawn a subsequent discovery sensor until then entire infrastructure is discovered (e.g.,  a host discovery will trigger the discovery of applications and services that reside on the host).
•Upon completion of discovery, TADDM processes the discovered component data to generate a topological representation of the infrastructure.Subsequent   discovery runs update the topologies, while maintaining a comprehensive Change history of the infrastructure configuration and dependencies.
