Enable or disable diagnostic context for a server instance

Diagnostic context provides unique context IDs for identifying requests that flow through the system. When diagnostic context is enabled for a server instance (and instrumentation is not enabled), a unique context ID for the request is returned when requested by the debug system or by an application.

If instrumentation is configured and enabled for a server instance, diagnostic context is enabled by default, so selecting Enable or Disable on this Console page will have no effect. To configure instrumentation, see Configure instrumentation for a diagnostic system module.

Note: If you configure instrumentation, you can further configure the dye vector in the DyeInjection monitor to identify certain attributes of requests, for example originating users and originating addresses. You can then configure dye masks in other diagnostic monitors to control which requests are handled by those monitors. For more information, see "Configuring the DyeInjection Monitor to Manage Diagnostic Contexts" in Oracle Fusion Middleware Configuring and Using the WebLogic Diagnostics Framework for Oracle WebLogic Server.

To enable or disable diagnostic context for a server instance:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the left pane, expand Diagnostics and select Context.
  3. Select the server or servers for which you want to enable or disable diagnostic context.
  4. Select Enable to enable diagnostic context or select Disable to disable diagnostic context for the selected server(s).
  5. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).
