Configure the XACTCommandQSpooler

Note: For information on overriding default configuration settings, refer to Modifying Configuration Settings.

The XACTCommandQSpooler process sends data from the RealTime database (RTDB) to the AVEVA Enterprise SCADA CloudData service. You will need to set up a spooler to use the Data Access Layer (DAL) configuration.

There will be multiple XACTCommandQSpooler processes running in the RealTime service, one process for each line in the RealTime_XACT.json file. A system-specific override file should be created for each system that will be communicating with the AVEVA Enterprise SCADA CloudData service.

Note: If you are configuring a cross-domain set-up, please contact your AVEVA customer support representative.

To configure the XACTCommandQSpooler

1. In the %DNADataRoot%\RealTime\config\Settings directory, either create or open the Realtime_XACT.json file.

2. Add the following contents to the file:

   {

   "RealTime": {

   "XACT": {

   "Queues": {

   "GasMeas_XFER": {

   "Size": 1024,

   "DALDirectory": "lspdcdss\\remote_RCS_XFER"

   }

   }

   }

   }

   }

3. Save the file.

4. Copy this file to the partner RealTime server.

5. Restart or start the RealTime service to pick up these changes to the RealTime_XACT.json file.

   In the oasErrLog.log file you should see a similar message to the following, indicating that the spooler is relying on the configuration:

   2017-09-24 13:22:37.052 XACT [TID=0x3688] - Started XACT spooler: -service GasMeas_XFER -qSize 1024
