WebCenter Startup Order Oracle WebCenter Topology

Introduction to Oracle WebCenter Administration 1-9 Serverservice unavailability does not prevent WebCenter applications from starting up, although errors may display while the application is running. 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.
