Out-of-bound conditions are also logged in managed server diagnostic logs so you can examine historical events at any time. Performance related messages are logged with the message ID prefix WCS-692<nn>and include the metric name, the value, and a message describing the metric that is out-of-bounds.
Here are some examples of messages that you might see in diagnostic logs for WebCenter Portal:

This section includes the following topics:
To view log messages for a WebCenter Portal application:
In Fusion Middleware Control, navigate to the home page for WebCenter Portal.
From the WebCenter Portal menu, select Logs > View Log Messages.
In the Log Messages page, search for warnings, errors, notifications, and so on.
To configure log files for WebCenter Portal:
For more information, see Viewing and Searching Log Files in Oracle Fusion Middleware Administering Oracle Fusion Middleware.
To help developers debug WebCenter Portal assets, administrators can enable error messages with the calling stack to be displayed in the WebCenter Portal error page.
Caution:
For security reasons, error messages should not be enabled in a production environment. Oracle recommends that you restrict error messages to development and staging environments.
To enable error messages:
Connect to the WebCenter domain's Administration server using WLST.
Create a new folder (/tmp/WCconfig) on your local file system.
Export the webcenter-config.xml configuration file to the /tmp/WCconfig folder you created by running:
exportMetadata(application='webcenter', server='WC_Portal', toLocation='/tmp/WCconfig', docs='/oracle/webcenter/webcenterapp/metadata/webcenter-config.xml')
Open the webcenter-config.xml file (in the /tmp/WCconfig/oracle/webcenter/webcenterapp/metadata) folder and change the showError-enable property to true to enable error messages:
<webcenter:showError-enabled>true</webcenter:showError-enabled>
or false to disable it:
<webcenter:showError-enabled>false</webcenter:showError-enabled>
Save the file and import it back to the Administration server using the following WLST command:
importMetadata(application='webcenter', server='WC_Portal',fromLocation='/tmp/WCconfig', docs='/oracle/webcenter/webcenterapp/metadata/webcenter-config.xml')
Note that you do not need to restart the Administration server for the change to take effect.
