Overview: Updating the JavaScript engine

The BIG-IP® system provides an option for updating the JavaScript engine, which improves client-side functionality and enhances protection of your BIG-IP® DataSafe™ profile. In the Engine Updates screen you can choose to download and install an engine update from the Update server when it is available, or perform a manual installation of an engine update from an update file you receive from F5.

Once daily, the BIG-IP system determines if engine updates are available from the Update server. If so, the system notifies you in the status area of the screen.

Note: If you are working with a group of BIG-IP systems that are in a trust domain and an update is performed on one of the BIG-IP systems in that group, all the other systems in that group are simultaneously updated as well.

Updating the JavaScript engine

Updating the JavaScript engine enables the BIG-IP® system to discover new types of generic malware.
  1. On the Main tab, click Security > Security Updates > Data Protection > Engine Update .
  2. Choose one of the following delivery modes:
    • Select Automatic if you want to download and install an engine update from the Update server if it is available.
    • Select Manual if you want to perform an engine update from an update file you receive from F5.
    If you set Delivery Mode to Manual, the Upload File setting appears.
    1. If you set Delivery Mode to Manual, at the Upload File field click the browse button to upload the engine update file you received from F5® support.
    Note: Setting Delivery Mode to Manual is a temporary setting and only valid as long as you are in the update screen. When you leave the update screen, Delivery Mode reverts back to Automatic.
  3. If you received a notification that updates are available or have uploaded an engine update file that you received from F5 support, click the Install Updates button to install the update.
    Note: The engine update takes from 2-4 hours to take effect.
  4. In addition to the notice that is displayed if the daily update check determines that an update is available, you can also check for available updates by clicking the Check for Engine Updates button.
    The Check for Engine Updates button is useful in the case where a new update has become available after the daily check was performed. If you click this button and an update is available, you will receive a notification.
