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.

The only exception is the Oracle Metadata Repository MDS, as WebCenter applications do not work without it. WebCenter Spaces partially works without the WebCenter repository but only if it is a different physical database from the MDS repository. The WebCenter repository stores information for several services, including Events, Links, Lists, People Connections, Polls, and Tags, and these services do not work if the WebCenter repository is not available.

1.3.5 WebCenter Configuration Considerations

The main configuration files for WebCenter applications are listed and described in Table 1–4 . Both these files are supplied within the WebCenter application deployment .EAR file. WebCenter applications and portlet producers both use the Oracle Metadata Services MDS repository to store their configuration data; both access the MDS repository as a JDBC data source within the Oracle WebLogic framework. The MDS repository stores post deployment configuration changes for WebCenter applications and portlet producers as application customizations. MDS uses the original deployed versions of adf-config.xml and connections.xml as base Oracle Content Server Documents Socket connection to the Administration Server. HTTP access is required only if the Oracle Content Server must be accessed outside WebCenter.
