CHARON-VAX application note
AN-037 CHARON-VAX as an automatic Service; dependencies and
restrictions
Author: Software Resources International

Updated: 24 January 2006

CHARON-VAX may be run as a standard service in Windows. See the CHARON-VAX user manuals
for details on how to use the CHARON Launcher and CHARON Service Manager to create and
manage CHARON services. Starting a CHARON-VAX service manually from the CHARON-VAX will
normally be completed without problem but review dependencies carefully before trying to start a
CHARON-VAX standard Windows Service automatically.
DEPENDENCIES
We recommend the following list of services, if used, as pre-requisites to starting CHARON-VAX as an
automatic service. With this list of pre-requisites CHARON-VAX starts without difficulty on Windows
XP and Windows 2003 Server Standard Edition when deployed on a correctly configured host system.
•

Tcpip (set by default)

•

Hardlock (set by default)

•

Serial

•

Packet

•

PCI

•

Processor

•

Cdrom

•

Disk

•

Fdc

•

Flpydisk

•

Eventlog

To display the pre-requisites of a service, go to Administrative Tools/Services, select the service and
click on Properties. The list of pre-requisites is displayed under the Dependencies tab.
To extend this list edit the registry using REGEDIT (Windows Registry Editor).
The default values of the DependOnService key of the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<charon service name> are set to
"tcpip" and “hardlock”.
To add a service to the list, double-click on the DependOnService key of the charon service you have
created and type the name of the services you wish to include as a pre-requisite.
STARTUP TIMEOUT
If after setting the required pre-requisites for a CHARON-VAX service you experience problems at
start up with the availability of hardware or services that are available when not running as a service,
use one of the following techniques to delay the start of the CHARON-VAX service in order to ensure
that all hardware and services are ready before the CHARON-VAX service starts.

CHARON-VAX application note AN-037
1. The CHARON service must be switched to "Manual"
2. Run an application installed as a service in "Automatic" mode. This application waits for a
defined amount of time and then starts the CHARON service.
Here is an example of a commercial version of such an application:

Solution 2:
The Microsoft support site describes an utility that can be installed as a service in automatic mode
that in turn runs batch files: http://support.microsoft.com/kb/q243486/
This description for W2000 also works for WXP/W2003.
