The IP conduit is used by ZENworks Handheld Management IP service clients to transfer messages. It is installed when the ZENworks Handheld Management Server or ZENworks Handheld Management Access Point is installed. For more information, see Novell ZENworks 7 Handheld Management Installation Guide.
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:
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.
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:
HKEY_LOCAL_MACHINE\SOFTWARE\Novell\ZENworks for Handhelds Proxy\Current Version\IP Conduit\Minimum Connect Retry
The setting at the server applies to all handheld devices.
By default, the registry value is 0. This default behavior means that the IP client on the handheld device waits 60 seconds plus the battery power auto shutoff setting on the handheld device (by default, 3 minutes) to connect to the IP conduit.
The values are in seconds. If you set the value to 25, ZENworks Handheld Management waits 25 seconds between retry attempts.
