Important Notes:

  • If you have previously installed the 'Filr 3.0 Security Update 1', this update is not required and will automatically show under 'Installed Patches'.
  • This update is provided via the Filr Online Update channel accessible via the Filr Appliance Configuration console (port 9443).
  • This update is required on the Filr, Filr Search and Filr MySQL appliance(s) in your deployment.
  • A reboot is required after applying this update.
  • The updates may take up to 20 minutes to complete depending on the number of updates being applied. For example, if you are updating from Filr 3.0 all the way to Filr 3.3, it may take up to 20 minutes for the update progress bar to complete. We recommend that you wait for the progress bar to complete and not disrupt the update process.
  • Recommended: In a Large or Clustered deployment, stop Filr service and update the Filr MySQL and Filr Search appliances first before updating the Filr appliance(s).


Installation: 
This update is provided via the Filr Online Update Channel. Please follow these steps on all Filr, Filr Search and Filr MySQL appliance(s) in your Filr deployment:

  1. Stop the Filr service on all Filr nodes and repeat Steps 2-7 in the following order: MySQL appliance first, then Search appliance(s) and Filr appliance(s) last.
  2. Login to the Filr Appliance Config (https://hostname:9443) as 'vaadmin' and select the Online Update icon.
  3. Toggle to the 'Needed Patches' in the patches download until you see the 'Filr 3.0 Security Update 2' patch update and then click 'Update Now' button.
  4. In the 'Update Now' pop-up, select:
        All Needed Patches: If you want to install all available updates 
        Security patches only: If you want to install the Security Updates only 

    Also select both of the following options:
        a. Automatically agree with all license agreements
        b. Automatically install all interactive patches
  5. Hit OK to apply the update.
  6. Toggle to the 'Installed Patches' in the patches download and verify the 'Filr 3.0 Security Update 2' patch update is shown as Installed.

Known Issues:

  1. The update progress bar shows progress but patch update never completes. This usually happens if the two options (shown in Steps 4a/4b above) are not selected. 
    To fix this problem, please cancel out of the update page and try installing the update again with the two options selected.
  2. It's been 20 minutes and the update progress bar is still spinning. Is it stuck? As noted in the Important Notes above, it may take up to 20 minutes for all updates to be applied depending on how many updates need to be applied. We recmmend that you wait for the progress bar to complete and not disrupt the update process for at least 30 minutes before contacting Micro Focus Customer Care. If you have cancelled out of the browser, and updates are no longer showing under 'Needed patches', chances are that the updates are still being applied in the background and the activity should be logged in the /var/log/zypp/history file.
  3. If configuring a new Filr 3.0 system for Online Updates for the first time using "SMT Server" or with a "Proxy Server", the registration may fail if the Filr server is in a private network.
    To fix this problem, please consult TID 7020906 for Proxy configuration and/or TID 7018759  for SMT configuration.
