Saving trace data for the Dgraph

You can save trace-level information to a file for any Dgraph managed by Enterprise Manger Cloud Control plug-in.

The Dgraph Tracing Utility runs automatically while the Dgraph is running. It stores the Dgraph target trace data it collects in trace files (.ebb).

Saving the trace data for the Dgraph is useful when working with Oracle Support to debug and diagnose issues. This option runs against a single Dgraph. The output file is referred to as a "blackbox" file and is named on-demand.pid.ebb.

To save the Dgraph's trace data:

  1. Log in to Enterprise Manager Cloud Control.
  2. Select a Dgraph target.
  3. From the Dgraph target menu, select Administration > Save Current Trace Data.
    A confirmation page displays.
    After you confirm, the following status displays:
    This image shows the save trace data operation and its output message.

Unlike other types of log files, you can't view the Tracing Utility files in Enterprise Manager. Therefore, after you have saved the current trace data for the Dgraph, you may need to download it, to share with Oracle Support.
