Using DUA

Hi,
My image contains a custom shell which will need updating in the field. Can
DUA be used to replace the shell program? Also I want to configure DUA to
look in a local directory for the update only once when the system boots. I
can set the local directory OK, but how do you configure DUA to only look for
the update only once during the boot?
thanks
kevin
 
Kevin,
Yes DUA can update your device in the field. With respect to having DUA
poll only once I would run a script or write an application which would
start the DUA service at start at boot time and stop the service when
turning off the machine or rebooting.

I can start DUA through another script or app, but wouldn't the shell exe
start first, then DUA would start? If so, how will DUA handle replacing a
program that is currently running?

Kevin:

I would think that you would be able to update your shell since its a file
in use like any other system file.

This is what I do... I have DUA in TD setup to not run at start and
everything in the poll date/time table is unchecked. At boot time the DUA
Service starts but does nothing.

When I want to install a QFE for example I have a bat file that does the
install. This install copies the dup file to the place that DUA is looking
based on my TD configuration. I then run a reg file that tells DUA to run:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DUAgent\Parameters\Con
fig]
"RunOnStart"=dword:00000001

Now, to actually get DUA to run and install the contents of the dup file I
stop then restart the DUA Service via:

net stop "device update agent"
net start "device update agent"

For updating a file in use, this is a snippet from a dus file from one of my
QFE updates:

MOVEFILE,0,1,C:\dua\working\gdi32.dll,1,C:\Windows\System32\gdi32.dll,DAMOVE
FILE_DELAY_UNTIL_REBOOT|DAMOVEFILE_REPLACE_EXISTING

Also, you don't mention EWF. If you use EWF then this gets a little more
complicated.

I haven't implemented EWF yet. This is my first go at XPe, so I am taking
everything one step at a time; bring up a generic image, bring up an image
with custom shell, include DUA, etc. I will try your suggestions and we'll
see how it goes.
thanks,
kevin

If you set DUA to run on start and uncheck everything in poll date/time, it
will check once (when the service starts). Since the service is normally
set to autostart, this will cause DUA to check once when rebooted. To
replace the shell, look at the help documentation on how to make your own
application the shell.
