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

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

  2. Go to File menu - click on Database Revision Control... - create a revision snapshot.

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

  4. Connect with GuiDBedit Tool to 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.

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

  9. Close the GuiDBedit Tool.

  10. Connect with SmartDashboard to 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:

    [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.
