Thomson Reuters Enterprise Platform for Real-Time Publishing Output Adapter Sample

By default, the publishing adapter listens on TCP port 14002. To use a different port, edit the RFA configuration file, rfa-config.xml, and change the <portNumber> parameter of the <RSSLProviderConnection> node to the desired value.

In the Package Explorer, double-click to open one of the four message model-specific sample applications: MarketPrice.sbapp, MarketByOrder.sbapp, MarketByPrice.sbapp, or MarketMaker.sbapp. Make sure the application is the currently active tab in the EventFlow Editor.

Select the adapter icon to open the Properties view for the adapter.

If you wish to publish to a different Reuters service than the default (DIRECT_FEED), click the Adapter Settings tab and change the Publish Service Name property to the desired value.

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

In the Test/Debug Perspective, open the Application Output view. Look for an event tuple emitted on the EventOut stream indicating the adapter succeeded in listening for incoming connections.

Use a TREP-RT subscribing client, such as one of the sample applications provided with the StreamBase TREP-RT Subscribing adapter, to subscribe to an item being published. Note that each sample application is driven by a message model-specific CSV file (such as MarketPriceFeed.csv) containing recorded feed data for the following items:

When the client subscribes to an item listed above, look for event tuples emitted on the EventOut stream indicating the client has established a session with the publisher (EventType=ClientSession) and has subscribed to an item (EventType=Item, Action=Subscribe). (When using the client in direct-connect mode, you might also see login and dictionary download event tuples.)

In the Manual Input view, select the DumpIn stream and click Send Data. One tuple per item being published appears in the Application Output view from the DumpOut stream. Items with active subscriptions are identified as such (table_ActiveSubscription=true).

In the Manual Input view, select the InfoQueryIn stream, enter ListSubscriptions in the Command field, and click Send Data. One tuple per active subscription (as recorded within the adapter) appears in the Application Output view from the InfoQueryOut stream. A marker with Done=true and all other fields null is the last tuple to appear on this stream.

In the Manual Input view, enter DumpDictionary in the Command field and click Send Data. One tuple per Reuters dictionary field appears in the Application Output view from the InfoQueryOut stream. A marker with Done=true and all other fields null is the last tuple to appear on this stream.

When done, press F9 or click the Stop Running Application button.

Open three terminal windows on UNIX, or three StreamBase Command Prompts on Windows. In each window, navigate to the directory where the sample is installed, or to your workspace copy of the sample, as described above.

In window 1, type:

sbd MarketPrice.sbapp

In window 2, type:

sbc dequeue -v

This window will display the tuples dequeued from the adapter's output ports.

Use a TREP-RT subscribing client, such as one of the sample applications provided with the StreamBase TREP-RT Subscribing adapter, to subscribe to one or more of the items being published by this sample.

In window 2, observe that event tuples are emitted on the EventOut stream, indicating the client has established a session with the publisher (EventType=ClientSession) and has subscribed to an item (EventType=Item, Action=Subscribe).

In window 3, type:

echo null | sbc enqueue DumpIn

In window 2, observe that a tuple is emitted on the DumpOut stream for each item being published. Items with active subscriptions are identified as such (table_ActiveSubscription=true).

In window 3, type:

echo ListSubscriptions,null,null | sbc enqueue InfoQueryIn

In window 2, observe that a tuple is emitted on the InfoQueryOut stream for each active subscription, as recorded by the publishing adapter.

In window 3, type:

echo DumpDictionary,null,null | sbc enqueue InfoQueryIn

In window 2, observe that a tuple is emitted on the InfoQueryOut stream for each field in the Reuters dictionary.

In window 3, type the following command to terminate the server and dequeuer:

sbadmin shutdown
