Running This Sample in StreamBase Studio

  1. Open the src/main/eventflow/packageName folder.

  2. Open the D3StreamingSample.sbapp file.

  3. Select the Digitec D3 Streaming adapter and select the Adapter Properties tab. Fill in the required information with your D3 server name and port.

  4. Click the Run button. This opens the SB Test/Debug perspective and starts the module.

  5. The file initial-subscribe.csv has two currency pairs that will subscribed to as soon as the adapter is connected to the D3 Pricing Engine.

  6. The UpdateOut output port emits tuples as market data is returned from the D3 Pricing Engine.

  7. If you wish to subscribe to other currency pairs, select the Manual Input view. Set the command field to subscribe, the SubscriptionID field to a unique string (such as someID1234), and the symbol field to a currency pair (such as GBPUSD). Click Send Data.

  8. When done, press F9 or click the Terminate EventFlow Fragment button.

Running This Sample in Terminal Windows

This section describes how to run the sample in UNIX terminal windows or Windows command prompt windows. On Windows, be sure to use the StreamBase Command Prompt from the Start menu as described in the Test/Debug Guide, not the default command prompt.

  1. Use StreamBase Studio to set up the Digitec D3 Streaming adapter properties as described in the previous section.

  2. Open two terminal windows on UNIX, or two StreamBase Command Prompt s on Windows. In each window, navigate to your workspace copy of the sample, as described above.

  3. In window 1, type:

    sbd D3StreamingSample.sbapp
