Diagnostic Images

Column Display     Related Tasks     Related Topics

A diagnostic image is a file that contains a snapshot, or dump, of a server's state and configuration data. Support personnel can use this data for post-failure analysis.

Use this page to change the default location to which a server writes its image file or to force a server to write its diagnostic image (capture the image).

The diagnostic image contains such data as the state and configuration of a server and its subsystems along with any data harvested from diagnostics modules that you have configured. For example it describes the value of the log cache, the status of work managers, and the JNDI state.

If WebLogic Server is configured with Oracle JRockit, and JRockit Flight Recorder is enabled, the diagnostic image capture includes WebLogic Server diagnostic data in a JRockit Flight Recorder file, which can be viewed in JRockit Mission Control. The volume of data that is produced for the Flight Recorder file in the diagnostic image can be customized. To use this capability, you must enable JRockit Flight Recorder and set the WLDF diagnostic volume to Low, Medium, or High.
