WebCenter Topology Out-of-the-Box Oracle WebCenter Topology

Introduction to Oracle WebCenter Administration 1-7 Figure 1–3 Oracle WebCenter Topology Out-of-the-Box Out-of-the-box managed servers host the following components: ■ WC_Spaces - Hosts WebCenter Spaces ■ WC_Portlet - Hosts WebCenter Portlets and WebCenter Pagelet Provider ■ WC_Collaboration - Hosts WebCenter Discussions and any additional WebCenter services that you choose to integrate ■ WC_Utilities - Hosts Activity Graph, Analytics, and Personalizations An optional fifth managed server an applications server can be used to run WebCenter Portal applications. When you create additional managed servers, they are provisioned with the appropriate libraries to enable them to draw upon the same external resources as WebCenter Spaces. For more information about managed servers, see Understanding Oracle Fusion Middleware Concepts in the Oracle Fusion Middleware Administrators Guide.

1.3.2 WebCenter Managed Servers

During Oracle WebCenter installation, the managed servers are provisioned with system libraries and Oracle ADF libraries. Table 1–2 lists the managed servers and the applications that run on them. 1-8 Oracle Fusion Middleware Administrators Guide for Oracle WebCenter

1.3.3 WebCenter Startup Order

When a managed server starts up, applications and libraries are started in the following order: 1. Oracle system libraries, known as the JRF libraries. 2. Oracle ADF libraries. 3. Instrumentation applications, such as Oracle DMS, and the Oracle Web Services Manager wsm-pm application. 4. WebCenter applications, shown in Table 1–2 . The startup order is also the order of dependency. If a dependent component does not deploy successfully, a later component may not function correctly. WebCenter application startup is not dependent on the availability of external services such as the discussions server, or other back-end servers. For details, see Section 1.3.4, WebCenter Dependencies.

1.3.4 WebCenter Dependencies

WebCenter applications use several external servers and services Table 1–3 . The Configuration column lists the type of information provided to Oracle WebCenter to configure or initialize the connection. The Access column lists the protocol used in run-time access of the service. Table 1–2 Oracle WebCenter Managed Servers and Applications
