Starting WebCenter Sites and Its Components in the WebLogic Server Console

The Oracle WebLogic Server Administration Console is a browser-based user interface that you use to manage a WebLogic Server domain. The Administration Server hosts the Administration Console, which is a Web application accessible from any supported Web browser with network access to the Administration Server.

To navigate to component functions in WebLogic Server:

1. Enter the WebLogic Server URL, which includes the name of the host and the port number assigned to WebLogic Server during the installation. The following shows the format of the URL.

   http://hostname.domain:port/console
   

   Port is the IP port number of the Administration Server running on Oracle WebLogic Server. By default, the port number is 7001.

2. Enter the system administrator user name and password and click Login.
3. From the navigation pane, expand the farm and then WebLogic Domain, and click Sites or the Visitor Services component.

   The domain page is displayed for your selection.

   In the WebLogic Server Administration Console, you can manage the environment including servers, clusters, virtual hosts, and work managers. See Getting Started Managing Oracle Fusion Middleware in Administering Oracle Fusion Middleware.
