Troubleshoot Management Console Issues

Use the information in this topic to resolve known issues that you may have encountered while working with the Oracle IoT Cloud Service Management Console.

  • Issue: A status code of 502 Proxy Error is received while a large batch registration is being processed.

    Description: If you are registering a large number of devices using the Batch Registration feature under the Devices menu, you may receive a status code of 502 Proxy Error while you are waiting for the batch registration to complete. If the progress indicator is still spinning when this error is displayed, it means your batch registration information has already been received and the request is still being processed by the Oracle IoT Cloud Service.

    Workaround: Continue to wait until the progress indicator has stopped spinning to get the actual results of your batch registration request.

  • Issue: If you are using a Firefox browser while scrolling the tables in the Messages or Alerts tabs of the Data page, you may not actually see all of the alerts and messages.

    Description: If you are using a Firefox browser to view the tables in the Alerts or Messages tabs in the Data page and you are scrolling using the mouse wheel, scroll up button, or scroll down button, the Alerts or Messages table will not display all of the actual data.

    Workaround: Grab the scroll bar for Alerts or Messages table and use it to scroll down or up to view all of data. You can also try using a different web browser.

  • Issue: The filter for Logging Level is not working correctly.

    Description: If you are viewing a gateway device’s log messages using the View/Edit page for Management tab under Devices, and you set the Logging Level in Logs tab to Warning, only the Warning and Severe messages should be displayed. Instead, Fine level messages are also displayed.

    Workaround: None known.

  • Issue: Exporting an IoT Application does not work when using a Safari browser.

    Description: The feature to export an IoT Application fails if you’re using a Safari browser on a Mac OS X platform. This issue is due to Safari bug https://bugs.webkit.org/show_bug.cgi?id=102914.

    Workaround: Use another browser, such as Chrome, when using the Export IoT Application feature.

  • Issue: An uploaded software that’s been installed on a device appears to have been deleted from that device after the uploaded software is deleted from Oracle IoT Cloud Service.

    Description: Using the Software page in the Devices tab of the Oracle IoT Cloud Service Management Console, if you upload a device software to the Oracle IoT Cloud Service software repository, install it on a gateway device, and then delete the uploaded software, the device software appears to have been deleted from the gateway device. In fact, the device software is still installed in the gateway device, but the Software tab in the gateway device’s details page no longer displays the information about the installed software.

    Workaround: None.

  • Issue: After you upgrade to Oracle IoT Cloud Service version 16.1.5 from an older version, any previous alert message counts are lost.

    Description: When you upgrade from a version of Oracle IoT Cloud Service prior to version 16.1.5, the history of the total number of alert messages displayed is lost and the number displayed in the Alerts and Messages page is zero. To view this number, click Devices at the top right of the Management Console UI and click Alerts and Messages on the left navigation area. In the Alerts tab, any alert messages received prior to the upgrade are no longer accounted for in the total number displayed in this Alerts tab.

    Workaround: None.

  • Issue: If you’re using a non-English locale, the time format used in the date selector fields of the Alerts and Messages page resets to the English format when the page is refreshed.

    Description: Choose a different language to use for your web browser and log in to your Oracle IoT Cloud Service instance. Click Devices from the Home page and then Alerts and Messages on the left navigation area. View the Alerts section. Notice the date format in the date fields at the top of the page. Refresh the current page using F5 and you will see that the date is changed to use the English format. The same occurs in the Messages section.

    Workaround: Alternately select the Alerts and Messages tab and the format displays back to the correct locale that your web browser is set to use.

  • Issue: When using a Firefox ESR browser version 38.x, the Unresponsive script error dialog may appear when viewing the detailed information about the devices.

    Description: If you’re using Firefox ESR browser version 38.x, click Devices and then select Management on the left navigation area. The Unresponsibe script error dialog will appear when you have more than 30 devices to display.

    Workaround: Upgrade to Firefox version 43 or later, or use another web browser, such as Chrome or Internet Explorer.

  • Issue: The graphic diagram that’s supposed to appear on the left-hand side of the Overview - All Devices section is blank when you use a Firefox ESR browser version 38.x.

    Description: Click Devices and then Management on the left navigation area. Expand the Overview - All Devices section. A diagram showing the states of the devices is supposed to appear on the left side. If you’re using Firefox ESR browser version 38.x, the diagram is not displayed.

    Workaround: Upgrade to Firefox version 43 or later. Or use another browser, such as Chrome or Internet Explorer.
