5.1 Viewing Content Server Status

You can view the current status (such as running or stopped) of the Content Server instance.

To view current Content Server status using Fusion Middleware Control:

1. In the navigation tree, expand the appropriate domain name (for example, Content_base_domain).
2. Expand WebCenter, then Content, then Content Server.
3. Select the Content Server instance name (for example, Oracle WebCenter Content - Content Server (UCM_server1)).
4. On the Content Server home page, you can view the current status of a Content Server instance.

5.2 Viewing Content Server Console Output

You can view console output from the Content Server instance. This shows the same information that is located in the DomainHome/ucm/cs/data/trace/classname.log file.

1. Choose Administration, then System Audit Information.
2. Click View Server Output.
3. To refresh the output messages, click Refresh Page. To clear the output messages, click Clear.

To access the Configuration Information page:

1. Choose Administration, then Configuration for instance.
2. To view details, click the link for each type of configuration information.

   Configuration information provided includes:

   • Server name

   • Version

   • Class loader

   • Instance directory

5.4 Viewing System Audit Information

Oracle WebCenter Content provides a System Audit Information page for a Content Server instance, which can be useful when troubleshooting a problem or adjusting the Content Server's performance.

The System Audit Information page provides several types of information.

• System Audit General Information

• System Audit Localization Information

• System Audit Tracing Sections Information

• System Audit Cache Information

• System Audit Configuration Entry Information

• System Audit Component Report Information

5.4.1 System Audit General Information

You can view general system audit numbers and details in the General Information section of the System Audit Information page.

To access the System Audit Information page, choose Administration, then System Audit Information.

• Amount of time the Content Server instance has been up and running.

• Number of server requests processed, and whether the system is handling server requests successfully. If the system is receiving too many requests, an email is sent to the system administrator regarding load performance.

• Total JVM memory capacity and total JVM available memory. Also information about the memory usage for the system, which may be useful in troubleshooting any "out of memory" errors you might receive. This can be important when running the Content Server instance with many users and a large quantity of data.

• Total number of threads, and information about which Java threads are currently running. This may be useful in determining the cause of an error.

• Total number of active database connections, and information about database activity.

• Total number of audit messages.

To view more details, click the link on the page for the type of configuration information.

5.4.2 System Audit Localization Information

You can view numbers about localization for your Content Server instance in the Localization Information section of the System Audit Information page.

To access the System Audit Information page, choose Administration, then System Audit Information.

5.4.3 System Audit Tracing Sections Information

You can view tracing details in the Tracing Sections Information section of the System Audit Information page. This section enables tracing in the Content Server instance and can be activated on a section-by-section basis. Tracing for active sections is displayed by clicking View Server Output on the System Audit Information page. Section tracing can be useful for determining which section of the Content Server is causing trouble, or when you want to view the details of specific sections.

To access the System Audit Information page, choose Administration, then System Audit Information.

• To view a list with brief descriptions of sections available for tracing, click the Info icon next to the Tracing Sections Information heading.

• To see in-depth tracing for any active section that supports it, select Full Verbose Tracing. For more information, see Using Tracing.

• To save tracing information, select Save.

• To specify additional sections for tracing, enter a comma-separated list of section names, or select sections from the menu next to the Active Sections field. The wildcard character * is supported; for example, using schema* will trace all sections that begin with the prefix schema. After specifying sections, click Update.

• To specify additional services to trace, enter a comma-separated list of service names in the Active Services field, then click Update.

• To specify additional threads to trace, enter a comma-separated list of thread names in the Active Threads field, then click Update.

• To specify what text to trap in the trace, enter the text in the Event Trap Text field, then click Update. For more information about using Event Trap, see the "Caught in the Act!" blog.

• To add a thread dump to the trace, select Add Thread Dump, then click Update.

• To return to the previous setting for any field you modified, click Reset.

Important:

Any options set in Tracing Sections Information will be lost when the Content Server instance is restarted unless you enable Save and click Update.

5.4.4 System Audit Cache Information

The Content Server instance caches various items for quick access. You can view current details for three caches in the Cache Information section of the System Audit Information page.

To access the System Audit Information page, choose Administration, then System Audit Information.

• Search cache: The number of permanently loaded pages and resource files. The number at which cache is temporarily capped. Whether any temporary items are loaded. Total number of distinct search queries being executed. Total number of distinct search queries being executed. These details are useful when troubleshooting any search related issues.

• Schema cache: Total number of items stored in schema cache. Number of bytes used out of number permitted. Additional details of any schema objects currently in cache.

• Buffer pool cache: Information about objects in cache and how much memory each object is using, which is reflected in the memory information of the System Audit General Information section. This information may be useful in pinpointing which object may be responsible for any memory leaks or other memory issues. (For information on troubleshooting, see Troubleshooting Oracle WebCenter Content.
