Volt configuration settings

Volt configuration settings are in VoltConfig.nsf in the volt folder of your Domino data directory (volt/VoltConfig.nsf). Use the Notes client or the Domino Administrator client to modify a configuration setting.

To modify a configuration setting, complete the following steps:
  1. Use Notes or the Administrator client to open volt/VoltConfig.nsf.
  2. Select All Settings.
  3. Find the setting you want to modify. For more information, see Common configuration settings.
  4. Open the setting document.
  5. Click Edit to modify the setting.
  6. If the setting is disabled, click Enable Setting.
  7. If necessary, modify the Setting Value field. See the description of each setting for a list of legal values.
  8. Click Done and select Yes to save your changes.

Volt typically reads a setting change within a minute or two. If your change does not take effect automatically, you may need to restart the HTTP process.

Common configuration settings

The following table lists the most commonly used Volt configuration settings. You can find additional configuration settings in VoltConfig.nsf. In each case, the document in VoltConfig.nsf includes a description of the setting.
Setting Description
  • customThemes.[ID].displayName
  • customThemes.[ID].location
  • customThemes.[ID].isDefault
  • customThemes.[ID].nl.[LOCALE]

The customThemes config settings define a list of customer-provided themes that can be used in Volt applications.

For each theme, two parameters must be set:
  • customThemes.[ID].displayName
  • customThemes.[ID].location

[ID] - An identifier for the custom theme (e.g. "corpTheme1"). The id can contain the letters 'a' through 'z' and numbers, and must start with a letter.

displayName - The theme name to be displayed in the Volt authoring UI.

location -The full URL of the theme's .css file.

For each theme, there are 2 optional parameters:
  • customThemes.[ID].isDefault
  • customThemes.[ID].nl.[LOCALE]

isDefault - If set to true, designates the theme as the default selection for new applications.

nl.[LOCALE] - For globalization support of the theme's display name. [LOCALE] is the locale code that identifies the language (e.g.,"en", "fr", "fr_CA", "zh").

After modifying these settings, restart the http task to see the changes in the authoring environment. If the location property of a theme is modified, any deployed applications using that custom theme need to be redeployed for changes to take affect.

  • customThemes.corpTheme1.displayName = Corporate Theme 1
  • customThemes.corpTheme1.nl.fr = Thème d'entreprise 1
  • customThemes.corpTheme1.nl.zh = 企业主题1
  • customThemes.corpTheme1.isDefault = true
  • customThemes.corpTheme1.location =https://mycompany.com/theme1.css

In some circumstances, files attached to either application designs or user-submitted records can become orphaned if the primary design or record element is removed outside the normal process. File records which are older than this number of hours and are no longer associated with an existing primary record are removed by a clean-up agent in VoltBuilder.nsf.

Default value: 48

Enables or disables JavaScript security in run time forms. When a form designer adds custom JavaScript to an application, this flag applies security settings to the custom JavaScript. This flag applies to the entire Volt server for all users.
Note: Setting this parameter to FALSE might expose users to malicious JavaScript. Only set to FALSE in a secured environment where Volt applications are created by trusted users.

If you change this value, any existing applications must be manually redeployed to apply the change. For more information, see JavaScript API for Volt.

Default value: TRUE


For certain scenarios is it necessary to indicate the front-end base URI used for Volt. All URI's that Volt generates will be based on this value.

The value must include everything necessary to connect to the Volt context, for example


With this entry, all emailed links, and absolute links visible during Volt design time start with this base URI regardless of what the user enters in the address bar.

  • servicesWhitelist.enabled
  • servicesWhitelist.[N].actions
  • servicesWhitelist.[N].domain

The servicesWhitelist config settings define a white list of domains and HTTP actions that app authors are allowed to call directly from their applications using URL based services.

In addition to setting servicesWhitelist.enabled=true, for each service two additional parameters must be set:
  • servicesWhitelist.[N].domain =
  • servicesWhitelist.[N].actions =

Where [N] is an integer number identifying that service. For more information, see the servicesWhitelist documents in VoltConfig.nsf.

Default value: true


When "true", Volt sends an email using the Internet address of the target user. If the user was found in an LDAP directory (via Domino directory assistance), the Internet address may be a more reliable way to route mail to the user. If the user was found in a Domino directory, the Internet address corresponds to the INTERNETADDRESS field in the user's person document.

When "false", Volt sends an email using the User ID of the user, letting the router determine the correct internet address to use if sending outside the Domino domain.

Default value: true
