Configuring NAS Services

  • Článek

NAS services are a middle-tier server component that executes business logic without a user interface or user interaction. NAS services in Microsoft Dynamics NAV Server support applications such as Microsoft Office Outlook Integration and the NAV Job Queue.

NAS stands for NAV Application Server, which was a component in earlier versions of Microsoft Dynamics NAV. NAS services replace the NAS component, and this requires you to modify any use of server-side COM. For more information, see Extending Microsoft Dynamics NAV Using Microsoft .NET Framework Interoperability.

Run NAS Services Applications in Dedicated Server Instances

It is recommended that you create a separate Microsoft Dynamics NAV Server instance for each NAS services application. See How to: Create a Microsoft Dynamics NAV Server Instance.

There are multiple reasons for running NAS services sessions in dedicated Microsoft Dynamics NAV Server instances:

  • Efficiency and convenience

    When you change any Microsoft Dynamics NAV Server setting, you must restart the instance for the change to take effect, which interrupts all services using that instance. So if you are running different types of services in the same instance—for example, RoleTailored client services and NAS services—making a change to the settings for either service type will require a server instance restart that interrupts all other service types running through that instance.

    Even for different types of NAS services applications it’s wise to run each application in a separate server instance. For example, if you will be using NAS services for a Microsoft Office Outlook Integration application and also for a Microsoft Dynamics NAV job queue application, create a separate Microsoft Dynamics NAV Server instance for each NAS services application. This way, if you need to modify settings for the Microsoft Office Outlook Integration application you will not affect the Microsoft Dynamics NAV job queue application, and vice-versa.

  • Performance

    Configuring NAS services applications to use separate server instances makes better use of the server computer’s resources, allowing you to run more applications with less degradation.

  • Efficient error tracking

    If a NAS services session terminates in an error, and there are no other services running on the Microsoft Dynamics NAV Server instance, the service instance terminates and can be handled like any other Windows service. For example, you could configure the Recovery tab on the Service configuration tool in Control Panel to restart or otherwise manage the service.

Configuring NAS Services Settings

You can configure NAS services by using the settings in Microsoft Dynamics NAV Server Administration tool. In a multitenent Microsoft Dynamics NAV Server instance deployment, some NAS services settings, such as enabling NAS services and running NAS services with admin rights, are specified when you mount the tenant on the Microsoft Dynamics NAV Server instance.

To configure NAS Services

  1. Start the Microsoft Dynamics NAV Server Administration tool, and open the Microsoft Dynamics NAV Server instance configuration.

    For more information, see Microsoft Dynamics NAV Server Administration Tool

  2. On the NAS Services tab, fill in the settings.

    For more information about the settings, see NAS Services Tab Settings.

    Important

    On the General tab, the Services Default Company specifies the default company that is used by NAS Services and also other types of client connections. NAS services sessions execute in the time zone specified by the ServicesDefaultTimeZone parameter for Microsoft Dynamics NAV Server. See. For more information about these settings, see General Tab Settings.

  3. If the Microsoft Dynamics NAV Server is a configured as a multitenant server, mount the tenant to configure the NAS services settings for the tenant.

    For more information, see How to: Mount or Dismount a Tenant on a Microsoft Dynamics Server Instance.

  4. Save the changes and restart the Microsoft Dynamics NAV Server instance.

  5. If you chose not to run NAS services with admin rights, add the service account for the Microsoft Dynamics NAV Server instance to be a user in Microsoft Dynamics NAV.

NAS Services and Languages

In multilanguage deployments of Microsoft Dynamics NAV, the language preferences and regional settings for the user account that NAS services settings runs as determine the formatting of the data. Language preferences for a user account can be set in Windows or in Microsoft Dynamics NAV. For example, in Microsoft Dynamics NAV, in the User Personalization Card window, you can specify a language for the user. But you can also set up a default language for the Microsoft Dynamics NAV deployment by creating an empty row in the User Personalization List window. If you create an entry where you specify a language but not a user ID, then NAS services will use that language unless the session runs with a user account where you have specified another language.

The following table illustrates how combinations of language personalization and regional settings impact data that a NAS services session processes. In this example, the NAS services session runs a computer where the regional settings are set to use the Spanish format. In Microsoft Dynamics NAV, the user account that the NAS services session runs as either has a language personalization or not.
