Configure the DAL on the RealTime servers communicating with the untrusted domain

To configure the Data Access Layer (DAL) on the RealTime servers that will communicate with the untrusted domain

1. On the RealTime servers, navigate to the %DNADataRoot%\Shared\config\DAL directory.

2. Copy the XML files that were created on the Measurement Advisor server in the untrusted domain to the RealTime server at the same location (%DNADataRoot%\Shared\config\DAL\<system>\remote_RCS_XFER). If the remote_RCS_XFER folder does not exist, then create the folder.

   Note: The remote_RCS_XFER folder must start with remote_.
   
   Important: Perform the following step on the SCADA servers. Do not perform it on the Decision Support System (DSS) machines.

3. On the SCADA servers, open the DALConfig_Default_remote.xml file and remove the following attribute, which will ensure that the communication is one way:

   <RemoteServiceProperty Name="AllowedSystemLinkConnections">GasMeasCloud_XFER:ESQL,GasMeas_XFER:SQL</RemoteServiceProperty>

4. Save the file.

5. Open the DALConfig_GasMeas_XFER_remote.xml file and add the <DriverAlias Alias="GasMeasCloud_XFER"> section as shown below.

   <DriverAlias Alias="GasMeasCloud_XFER">

   <DriverType Type="ESQL">

   <TransportType>Remote</TransportType>

   <DriverProperty Name="RemoteServiceAlias">default</DriverProperty>

   <DriverProperty Name="CertificateType">SystemLink</DriverProperty>

   </DriverType>

   </DriverAlias>

6. Copy the DAL files to the partner system to each SCADA RealTime service that will be communicating with Measurement Advisor in the untrusted domain.
