35 Administering WebCenter Sites and Its Components in Enterprise Manager
Topics:
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:

Oracle WebCenter Sites: Visitor Services
To navigate to Oracle WebCenter Sites Enterprise Management pages in Oracle Enterprise Manager:
Viewing the Home Pages of WebCenter Sites and Its Components
You can view the status of Oracle WebCenter Sites or Visitor Services server using Oracle Enterprise Manager or Oracle WebLogic Server. The home pages for Oracle WebCenter Sites and Visitor Services in Oracle Enterprise Manager display the status of your system. The home pages display the state, version, and uptime of the Oracle WebCenter Sites and Visitor Services systems.
To view the status of your Oracle WebCenter Sites or Visitor Services system installation:
You can navigate to the home page from any other page by clicking Home in the component menu options in the right pane.
Note:
For more information about viewing the status of your Oracle WebCenter Sites or WebCenter Sites: Visitor Services system using the Oracle WebLogic Server administration console, see the Oracle WebLogic Server documentation.
Managing Log Files for WebCenter Sites and Its Components
You can enable logging of configuration messages, debug messages, and trace messages and configure the log files using Oracle Enterprise Manager.
This section includes the following topics:
Configuring Log File Settings for WebCenter Sites and Its Components
By default, errors, warnings, and major application life cycle events in Enterprise Manager are logged on the application server. As a system administrator, you can progressively increase the log level to enable logging of configuration messages, debug messages, and trace messages. You can use Oracle Enterprise Manager to view and configure log messages for your WebCenter Sites system. For more information about managing log files, see Managing Log Files and Diagnostic Data in Administering Oracle Fusion Middleware.
The {weblogic_server_name}
is the name of the WebLogic Server, for example VisitorServices01 or Sites01
.
Out of the box, the log files are named sites.log
and cas.log
, and are created in the application server log directory.
You can configure the log files for WebCenter Sites using Oracle Enterprise Manager.
You can configure the names and locations of log files, the size of the log files, the level of information written to the log files, the format, and the Locale encoding, as described in Configuring Settings for Log Files in Administering Oracle Fusion Middleware.
Monitoring the Performance Metrics of WebCenter Sites and Its Components
For information about monitoring the Oracle WebCenter Sites or Visitor Services system, including an overview of monitoring and viewing the status of your system, see these topics:
Note:
You can set theCURSOR_SHARING
initialization parameter to FORCE
to enhance the performance of WebCenter Sites. If you set the CURSOR_SHARING
initialization parameter to FORCE
, the database replaces literals with system-generated bind variables.
Viewing the Status of WebCenter Sites and Its Components
You can view the status of Oracle WebCenter Sites or Visitor Services using Oracle Enterprise Manager or Oracle WebLogic Server. The component home page in Oracle Enterprise Manager displays the status of your component system. It displays the state, version, and uptime of the component system.
To view the status of your component system installation:
You can navigate to the home page from any other page by clicking Home in the component menu options in the right pane.
Note:
For more information about viewing the status of your component system using the Oracle WebLogic Server administration console, see the Oracle WebLogic Server documentation.

JDBC Info
Metric Name | Description |
---|---|
ActiveConnectionsAverageCount |
Average number of active connections in this instance of the data source. Active connections are connections in use by an application. |
ActiveConnectionsCurrentCount |
The number of connections currently in use by applications. |
ActiveConnectionsHighCount |
Highest number of active database connections in this instance of the data source since the data source was instantiated. Active connections are connections in use by an application. |
ConnectionDelayTime |
The average amount of time, in milliseconds, that it takes to create a physical connection to the database. The value is calculated as summary of all times to connect divided by the total number of connections. |
ConnectionsTotalCount |

MaxCapacity |
Maximum number of physical database connections that this connection pool can contain. Different JDBC Drivers and database servers may limit the number of possible physical connections. |
NumAvailable |
The number of database connections that are currently idle and available to be used by applications in this instance of the data source. |
PrepStmtCacheAccessCount |
The cumulative, running count of the number of times that the statement cache was accessed. |
PrepStmtCacheAddCount |
