How to clear URL Filtering kernel cache? Technical Level
Solution

Follow these steps to clear the URL Filtering kernel cache on a Security Gateway / cluster:

  1. Connect with SmartDashboard/SmartConsole to the Security Management Server / Domain Management Server.

  2. Go to File menu - click on Database Revision Control... - create a revision snapshot. (This feature is not available in R80.XX+)

  3. Close all SmartConsole windows (SmartDashboard, SmartView Tracker, SmartView Monitor, etc.).

  4. Connect with the GuiDBedit Tool to the Security Management Server / Domain Management Server.

  5. In the upper left pane, go to Table - Other - rad_services.

  6. In the upper right pane, select urlf_rad_service_0.
  7. In the lower pane, right-click on the policy_install_cache_override - select Edit... - select "true" - click on OK.

    Example:



  8. Save the changes: go to File menu - click on Save All.

  9. Close the GuiDBedit Tool.

  10. Connect with SmartDashboard/SmartConsole to the Security Management Server / Domain Management Server.

  11. Install the policy only on the involved Security Gateway / Cluster object.
  12. Verify that the URL Filtering kernel cache table is empty on the involved Security Gateway / cluster members:

    Version R80.30 Gaia 3.10 and above: 
    [Expert@HostName]# fw ctl multik print_bl urlf_cache_tbl -s
    Lower version Gaia 2.6.18:
    [Expert@HostName]# fw tab -t urlf_cache_tbl -s

    Output should be:

    HOST                  NAME                               ID #VALS #PEAK #SLINKS
    localhost             urlf_cache_tbl                    XXX     0     0       0
    
  13. CRUCIAL STEP: Restore the default value for policy_install_cache_override ("false"):

    Note: If default value ("false") is not restored, then URL Filtering kernel cache will be cleared on each policy installation.

    1. Close all SmartConsole windows (SmartDashboard, SmartView Tracker, SmartView Monitor, etc.).

    2. Connect with the GuiDBedit Tool to the Security Management Server / Domain Management Server.

    3. In the upper left pane, go to Table - Other - rad_services.

    4. In the upper right pane, select urlf_rad_service_0.

    5. In the lower pane, right-click on the policy_install_cache_override - select Edit... - select "false" - click on OK.

    6. Save the changes: go to File menu - click on Save All.

    7. Close the GuiDBedit Tool.
  14. Connect with SmartDashboard/SmartConsole to the Security Management Server / Domain Management Server.

  15. Install the policy on the relevant Security Gateway / Cluster object.
