About Oracle Customer Hub (UCM) Architecture

Oracle Customer Hub (UCM) is based on the n-tier object architecture of Siebel Business Applications in which the user interface, business logic, and data are separated and layered. Each tier contains a set of objects and components, which allows a high degree of reuse. The consolidated object layer enables uniform communication between channels and interfaces. This architecture also allows flexible deployments and integration with new business processes and systems. Figure 2 shows the Oracle Customer Hub (UCM) architecture.

Oracle Customer Hub (UCM) architecture is designed for extreme fault tolerance with zero downtime. The database platform includes the following:

• High-availability upgrades and online upgrades of the production environment.
• Enhanced cluster support that allows automatic and transparent fail-over between servers and eliminates single points of failure.
• Database auto-reconnect, which allows servers to continue operating after a temporary outage without any intervention.
• Server-component reconfiguration without stopping current tasks or client sessions.
• Supports multithreaded and interactive components, except background-mode components.
