As of April 10, 2012 Hach WIMS Live Update is no longer supported.

The Hach WIMS's Live Update is a background Windows Service that periodically checks for Hach WIMS patches. Only one instance of Live Update is required for each Hach WIMS database.

INI Settings:

There are several settings for Live Update which it loads from an INI file, the first group of settings is explained in the Hach WIMS Database Connection Settings article.  That article explains the basic settings required for all Hach WIMS Services and applications that connect directly to the Hach WIMS database.  To add to those settings, Live Update has a few extra settings, explained here:

HTTP
(Required)

This is the internet address of the update server Live Update will use when checking for updates. Currenly available location is :  http://www.opssys.com/support/LiveUpdate/LiveUpdate.aspx

KEEPLOGSFOR
(Optional, Default=1000)

Determines the number of days that Live Update will keep its own log files.  Once a log file is older than the specified number of days, it is deleted from the system.

PROXY
(Optional)

This determines the proxy server's network or IP address, if you are using one.

PROXYPORT
(Optional)

This is the Proxy server's TCP/IP port number, if you are using one. Used with PROXY above.

FIXSCHEDULEAT
(Optional)

If a value for this setting is specified, it will be used as an offset (in minutes) from 2:59 AM (local time) for when the service would check the update server for new patches. If not specified, the offset is generated randomly. 

HACHWIMS_USERMSG_SENDTO
(Optional)

Use one (or more) line(s) of this setting to limit the amount of users that will be receiving routine notification messages from the service. For Example,

HACHWIMS_USERMSG_SENDTO=SUPER
HACHWIMS_USERMSG_SENDTO=SMITH
HACHWIMS_USERMSG_SENDTO=JANEDOE

would only send notification messages to SUPER, SMITH, and JANEDOE users.

All of the settings are found in the Live Update ini file: liveup.ini.  This file is found in the Live Update installation folder which is specified during installation (default: C:\HachWIMS\LiveUpdate).  If any of the settings needs to be changed in the INI file, you must save the changes to the file and then restart the Live Update service: see "MAINTENANCE" below for details.

MAINTENANCE:

Periodically, due to unforseen circumstances, the Live Update NT service can require restarting and even updating.  To start, stop or restart the service, we recommend using the provided links in the Windows Start Menu as show below:

NOTE (For Windows Vista Users): If you are running Microsoft's Windows Vista and are having trouble using the above Start menu shortcuts, please see HOWTO: Start/Stop/Restart Hach WIMS Services under Windows Vista.

For advanced users, this can also be done through the Windows Service Manager (Start, Run, services.msc, OK).  From this window, you can check the status of the service (started or not) and start, stop and restart the service:

ADVANCED USERS: 

The service must be stopped before installing an updated version of the Live Update NT service.  This prevents the service from being abruptly halted during an operation by the upgrade process.  Once the upgraded version is installed, see the above maintenance section on how to ensure that your Live Update service is operational and how to start or restart it if necessary.
