Explanation/Reference:
Oracle offers a comprehensive SOA solution through a suite of SOA products. Oracle Fusion Middleware products cover the needs of the SOA infrastructure end-to-end.
The figure below shows the mapping of Oracle products to the SOA logical components.
Management of services is extremely important in SOA environments, where services are integrated, reused, and constantly changed. Oracle Enterprise Manager (OEM) simplifies monitoring and managing SOA environments. It addresses each of the challenges by helping model, monitor, and manage the SOA environment.
The products referred in the figure are:
* OSB - Oracle Service Bus
* OSR - Oracle Service Registry
* OER - Oracle Enterprise Repository
* OWSM - Oracle Web Service Management
* OEM - Oracle Enterprise Manager (with SOA management pack)
* IdM - Identity and Access Management
There isn't necessarily a one to one mapping between logical architecture components and products.
While some products target a specific logical need, most provide additional features, such as monitoring, management, and security.

Note:
The SOA infrastructure capabilities can be grouped into the following logical components as shown in Figure below.
* Service Bus
* SOA Security Framework
* Service Registry
* Metadata Repository
* Monitoring Framework3-2 ORA SOA Infrastructure
* Management Framework
