Overview

The Range Aware Key Server is a new Key Server implementation introduced to support Configuration Transport Manager (CTM). CTM is used to transport administrative configuration data (Business Objects) between systems. Each Business Object is comprised of a number of entities. Each of these entities has a primary key. The standard Key Server implementation only guarantees uniqueness of a primary key within a single system installation. This means that when a Business Object is transported from a Source System and applied on a Target System, there is the strong possibility of key clashes between the transported entities and the existing entities on the system.

The Range Aware Key Server implementation is responsible for creating primary keys to meet the following requirements:

• Prevent clashes in primary keys between new entities transported to a system and existing entities on that system.
• Identify where there is an existing version of a transported entity on a system, so that the existing entity is updated with the transported entity data.
