5.5 Rebooting to restricted mode

WLI installs and configures when security mode is set to maintenance. This mode disables all WLI file and resource protection, allowing the installer to complete all the previous steps.

After all administrator keys are authorized and a WLI database backup is generated, the system can be rebooted for WLI to operate in restricted mode:

%wlisyspolicy -s mode=restricted -k <wli_admin_key> The following must be executed by root user:

#shutdown -r

Following reboot, WLI is completely operational in the secure restricted mode.
