The Jet Remote Data Service Data Source for NAV - Admin Guide


Expert

Overview

The Jet Remote Data Service (JRDS) data source presents a three-tier architectural design with a service component that is hosted within Internet Information Services (IIS).  It provides a fast, secure connection method for environments where Excel is installed locally and the Dynamics NAV system is hosted on a different domain .

The Jet Remote Data Service

This video provides an in-depth look at the Jet Remote Data Service available for Dynamics NAV.

Requirements

Host Server Requirements

  • Using Dynamics NAV 2013 or later
  • SQL Server and its corresponding SQL Server client must be installed
  • Internet Information Services (IIS) with an SSL/TLS certificate
  • PowerShell 4.0 (or higher)
  • The name of the host server must be exposed through DNS if users will access it via a URL
  • The service must have access to a SQL account or Windows Login which has ‘read’ access to the NAV database.  While the user’s NAV credentials are used to determine the user’s *permissions* to access data, accessing the database itself requires a separate database login with “read” rights
The recommended best practice is to set up a single new user account with read access to the database.  Then, use the Jet Administration Console to create a data source using the credentials for this new account, and share that data source with any Jet users who will need to use the data source. In this way, Jet users have access to the data without having to know the credentials associated with the new user account.

End User (client) Requirements

  • The Jet Excel add-in must be installed on the local computer.

To connect to the service, end users will need to know...

  • The URL or IP address of the Host Server
  • The Port configured for use with the JRDS
  • The Instance Name of the Service Instance
  • Their NAV Windows Authentication username, domain and password

Terminology

  1. "Jet Remote Data Service" vs "JRDS Data Source"

    jrds.png

  2. Jet Remote Data Service

    The JRDS consists of an Application Container and one or more Service Instances.

    In mult-tenant environments, each hosting client must have a distinct service instance with its own data source settings. This ensures that no hosting client can access data from another hosting client.

  3. The Application Container

    The Application Container is the term used to refer to the IIS website that will host the Service Instance(s). The Application Container is associated with a port during installation.

  4. Service Instances

    The Application Container must include one or more Service Instances. Each Service Instance must be uniquely named and provides access to a single NAV data source (or a single NAV Tenant data source in a multi-tenant environment).

    In a multi-tenant environment all clients may connect to their data via the same port, but each client will connect to their own service instance.

Jet Remote Data Service Administration Shell

The Jet Remote Data Service is installed and configured using the Jet Remote Data Service Administration Shell , which is a PowerShell management module.

Launching the Jet Remorte Data Service Admin Shell

The MSI file can be used (with the Windows Installer for other installation tool) to install the Administration Shell into a “Jet Remote Data Service” directory in the appropriate “Program Files” directory.

Along with the Administration Shell, the MSI also installs the service assemblies and a shortcut in the Start Menu (to access the administration shell).

Click DOWNLOAD to download a zip file containing both the 32-bit and 64-bit installer:

DOWNLOAD

The bit-level you install should match the bit-level of the version of the operating system (usually 64-bit for recent versions of WIndows Server).

There are two ways to initialize the management module. The first is to use the shortcut called “Jet Remote Data Service Administration Shell”. This must be run as administrator and will open an instance of Powershell.

Alternatively, the initialization script (JetRemoteDataServiceAdministrativeShell.ps1) can be found in the Management folder of the install directory and run manually via the PowerShell prompt running as administrator.

Installing a Jet Remote Data Service

The Jet Remote Data Service Administration Shell provides a set of PowerShell cmdlets which are used to create, configure and remove Application Container and Service Instances. Each of the available cmdlets and their common uses are listed below.

Installation Steps

  1. New-JetRemoteDataService

    This command creates the Application Container and must be called prior to calling other Jet cmdlets.

    The parameter -Port is required and indicates the port that will be used for the website address binding.

    This command must be called prior to calling New-JetNavRemoteDataServiceInstance

    Example:

    PS C:\> New-JetRemoteDataService -Port 443
    The port used will need to have an inbound Windows firewall rule in place. Jet Reports recommends that port 443 be used.

    This creates a new, empty website in Windows IIS that is named Jet Remote Data Service Container which serves as the container for service instances of the JRDS.

    Supported Parameters

    Parameter Description Type of Value Example Value or Description
    -Port The port to be used by the Jet Remote Data Service Numeric 443
    The command does support other parameters.  For additional details, you can use the PowerShell "get-help" cmdlet

    Jet cmdlets also support the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, and OutVariable. For more information, see about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216)

  2. New-JetNavRemoteDataServiceInstance

    This command creates a service instance of the JRDS.

    This command can be used multiple times to create multiple Service Instances.  The New-JetRemoteDataService command must be called prior to running this command.

    Example:

    PS C:\> New-JetNavRemoteDataServiceInstance -InstanceName "Customer" –Server “Jet-Test” –Database “NAV Demo Database” -AuthenticationType 2 –UserID “UserName” –Password “paSSw0rd”

    When a new service instance is created:

    1. An instance directory is created in the IIS website root directory that contains a symbolic link to the installed service assemblies and a “Web.config” file. This new directory is loaded into the Application Container as a virtual directory whose path is the name of the instance, and within that virtual directory the symbolic link is loaded as an application.
    2. The instance application will be given its own Application Pool within IIS. This results in an instance-specific IIS process being created for each service hosted in the Application Container.
    A virtual directory in the Application Container is mapped to a distinct instance directory and the link to the service assemblies is located as an application.
    The figure above shows a virtual directory inside of the Application Container and the location of the actual directory in the file system.  Within that instance directory, a symbolic link is pointing to the location of the service assemblies (which in this example is the default installation directory).

Configuring User and Group Access

The Jet Remote Data Service Administration Shell provides a set of PowerShell cmdlets which are used to create, configure and remove Application Container and Service Instances. Each of the available cmdlets and their common uses are listed below.

End-to-end Configuration of the Jet Remote Data Service 

Using the tools discussed above, we’ll now look at a step-by-step walkthrough of setting up the Jet Remote Data Service and a data source connection to it in the Jet Excel add-in.

An important distinction to remember is the different between:
  1. The JRDS instance configuration to the database, and
  2. The configuration in the Jet Excel add-in for connecting to the JRDS

Individuals in charge of configuring the JRDS in IIS will need to configure the JRDS instance's connection to the database.

Jet users will then need to configure their connection to the JRDS

 

  1. Creating and Configuring an Instance of the JRDS

    Hosting providers will need to configure the following items.

    The recommended configuration is to use an AuthenticationType of SqlServer for the database.  This makes it easier to manage security.

    Here is an example of creating a new service instance for a customer named “JetReports” using port 443 on a server named “Jet-Test”:

    Example Command:

    PS C:\> New-JetRemoteDataService -Port 443 
    PS C:\> New-JetNavRemoteDataServiceInstance -InstanceName "JetReports" -Server "Jet-Test" -Database "NAV Demo Database (33781)" -UserID "User" -Password "PaSSw0rd" 

    The bare minimum settings have been configured to make this data service usable. Note that without any drilldown configuration, no user will be able to perform drilldowns using the RTC or Web Client.

  2. Binding the Security Certificate

    *** IMPORTANT MANUAL STEP ***

    When the Application Container is created, no security certificate (e.g., SSL/TLS) is configured for it.  In order to complete this step, Windows IIS Manager must be opened and the binding on the site entitled Jet Remote Data Service Container must be configured to use a security certificate, as shown below

    fig: configuring the security certificate for use with the Application Container

    It is important that a trusted certificate be used.  Additionally, the site that the certificate was issued to must be the site used in the "Server" value when configuring your users' Jet data source settings.  Failure to follow these guidelines may result in certificate warnings for your users and an inability to connect to the data source.  See the certificate properties and data source settings shown below.

     

  3. Configuring the Data Source Connection in the Jet Excel add-in

    The first step in the Jet Excel add-in is to create a new data source of the type Dynamics NAV 2013 and later (Remote Data Service).

    Next, the authentication needs to be configured.  The user can authenticate against the JRDS using specified Windows credentials.

    It is expected that users will be given a username, domain, and password to use for authentication (the same one they use to connect to the NAV RTC or Web Client).

    Finally, the connection information for the instance of the JRDS must be configured:

    Note that the Server is the one which is hosting IIS and the JRDS.  The Port is the one which was entered into PowerShell when the Application Container was created.  The Instance is the name entered into PowerShell when the Service Instance was created.

    The dropdown to select the company will populate when opened if the settings are correct.

    All remaining settings are typical of other NAV data sources with the exception of Drilldown.  As noted above in the parameter list for the New-JetNAVRemoteDataServiceInstance command, hosting providers will configure the drilldown settings (RTC/Web Client server, instance, port, and whether SSL should be used) when configuring the JRDS instance.  The only configuration a user must make is to select the desired drilldown type and, in the case of RTC drilldown, the directory where the RTC is installed.

  4. Important Note

    When upgrading versions of Jet to a much newer release, ensure that both the Jet Remote Data Service version installed on the server and the client versions are on the same version to reduce potential issues.
