Configuring Bandwidth Usage; Configuring Client Retries And Power Down (Or Suspend) - Novell ZENWORKS HANDELD MANAGEMENT 7 SP1 IR4 - ADMINISTRATION Administration Manual

You can configure how much bandwidth ZENworks Handheld Management should allow when the
handheld IP client connects to the IP conduit and how often clients should try to connect to the IP
conduit after failing to connect.
These settings are found in the registry on the IP conduit machine (the sync machine).
The following sections contain additional information:
Section 7.5.1, "Configuring Bandwidth Usage," on page 142
Section 7.5.2, "Configuring Client Retries and Power Down (or Suspend)," on page 142

7.5.1 Configuring Bandwidth Usage

If you have a very limited bandwidth (for example, a wireless network where multiple applications
use the TCP/IP connection), you can limit how much bandwidth the ZENworks Handheld
Management handheld IP client should use.
On the IP conduit machine (the sync machine where the Desktop Synchronization Integration is
installed), the throttle setting is found in the value name Throttle in the following registry entry:
HKEY_LOCAL_MACHINE\SOFTWARE\Novell\ZENworks for Handhelds Proxy\Current
Version\IP Conduit\Throttle
By default, ZENworks Handheld Management is configured to use 100 percent of available
bandwidth, which is a setting of 100 (decimal) in the Throttle value. If you set it to 50, ZENworks
Handheld Management uses just 50 percent of available bandwidth.
If you change this setting, you should test how it works in your environment. Lowering the throttle
value causes ZENworks Handheld Management messages (that is, applications) to take longer to
download to the handheld device.

7.5.2 Configuring Client Retries and Power Down (or Suspend)

Windows CE devices power down or suspend by default after a predefined number of minutes of
inactivity. This counter is reset if there is any activity on the device (for example, a synchronization,
using the keyboard, and so forth).
Because the IP client periodically attempts to connect to the IP conduit after a failed connection, the
counter is reset whenever the IP client attempts to connect to the server. To prevent this, the IP client
uses a default retry connection interval of 60 seconds plus whatever the battery power off setting is
(by default, 3 minutes).
Without this default, the device might never power down or go into suspend mode.
On the other hand, if your users only connect for short periods of time, the interval might be set too
high for the client to connect to the IP conduit and therefore your users might not connect to the IP
conduit frequently enough.
If your users connect for short periods of time and you are concerned that they might not be getting
their ZENworks Handheld Management messages because the minimum connection interval is set
too high, you can change the Minimum Connect Retry value in the registry.
This value is found in the registry on the IP conduit machine in:
