Tervela Adapter Sample

In the Package Explorer, double-click tervela.sbapp.

Select the Definitions tab and modify the schema of the PublishSchema named schema to match that of the messages you wish to publish.

Select the Parameters tab and enter your site-values for username, password, and tmxaddress1, and, if appropriate, tmxaddress2.

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

Enter in the Topic(s) property one or more topics, separated by spaces, you would like to subscribe to when the application starts. You can subscribe to additional topics after the application starts by enqueuing tuples to the Subscribe stream.

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

Enter the topic you want to publish to in the Default Topic property. Note that the default topic can be overridden in each publish tuple.

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. If the adapters are able to connect and log in to the TMX server(s), two Login status tuples with a Succeeded action appear, one from each Tervela adapter instance.

In the Manual Input view, select the Publish input stream, enter values in more or more fields, and click Send Data. A tuple will appear in the Application Output view from the Data streams.

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 your workspace copy of the sample, as described above.

In window 1, type:

sbd tervela.sbapp

In window 2, type:

sbc dequeue -v

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

In window 3, enqueue a tuple to be published (adjusting the number of field to match your Publish schema):

echo MyTopic,MyBlob,true,1.23,123,1234,MyString,2010-03-24,null | sbc enqueue Publish

Observe in windows 2 the published tuple appears on the Data stream.

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

sbadmin shutdown
