# Thomson Reuters Enterprise Platform for Real-Time Subscribing Input Adapter Sample

## Introduction

This sample demonstrates the use of the TIBCO StreamBase® Adapter for Thomson Reuters Enterprise Platform for Real-Time Subscribe (formerly known as the Thomson Reuters RMDS Subscribing Input Adapter).

## Importing This Sample into StreamBase Studio

In StreamBase Studio, import this sample with the following steps:

- From the top-level menu, select File → Load StreamBase Sample.

- In the search field, type `thomson` to narrow the list of samples.

- Select Thomson Reuters Enterprise Platform for Real-Time Subscribing Input adapter from the StreamBase Market Data Adapters category.

- Click OK.

StreamBase Studio creates a project for this sample.

## Preparing to Run the Sample

1. Edit the RFA configuration file, `rfa-config.xml`. Changing the P2PS (`<serverList>` and `<portNumber>`) parameters to match the Reuters infrastructure at your site.

2. If you want to subscribe to one or more items when the adapter starts, add lines to the initial subscription file, `initial_subscriptions.txt`. This file contains a number of commented-out example subscriptions you can use as a starting point.

## Running This Sample in StreamBase Studio

1. In the Project Explorer view, open the sample you just loaded.

   If you see red marks on a project folder, wait a moment for the project to load its features.

   If the red marks do not resolve themselves after a minute, select the project, right-click, and select Maven → Update Project from the context menu.

2. Open the `src/main/eventflow/`packageName`` folder.

3. In the Project Explorer view, double-click to open one of the four message model-specific sample modules:

   `MarketByOrder.sbapp`
   `MarketByPrice.sbapp`
   `MarketMaker.sbapp`
   `MarketPrice.sbapp`

   Make sure the selected module is the currently active tab in the EventFlow Editor.

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

5. Select the Adapter Settings tab and enter values for Username, Position, and Application, if required at your site. (At many sites, one or more of these parameters are unused, and can be left blank.)

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

7. In the Test/Debug Perspective, open the Output Streams view. If connectivity to your RFA infrastructure is configured correctly, look for several event tuples emitted on the `Events` stream. Events provide the login and dictionary load status. If you have added initial subscriptions to the `initial_subscriptions.txt` file, look for tuples emitted from the `MarketData` stream as well.

8. In the Manual Input view, select the `InfoQueryIn` stream, enter `ListSubscriptions` and `MyTag` in the `Command` and `Tag` fields, respectively, and click Send Data. One tuple per initial subscription appears in the Output Streams view from the `InfoQueryOut` stream. A marker with `Done=true` and all other fields `null` is the last tuple to appear on this stream.

9. In the Manual Input view, select the `DynamicSubscribe` stream. Enter values in the `Service` and `Item` fields. (If using the Market Feed sample, you can enter a four-part subject value in the `Subject` field instead). Enter `true` in either the `Subscribe` or `Snapshot` fields and click Send Data. If the item you entered is active, look for one or more tuples representing the item's initial state emitted on the `MarketData` stream in the Output Streams view. If you enter `true` in the `Subscribe` field, a series of update tuples is emitted from the `MarketData` stream as well.

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

## Sample Location

When you load the sample into StreamBase Studio, Studio copies the sample project's files to your Studio workspace, which is normally part of your home directory, with full access rights.

### Important

Load this sample in StreamBase Studio, and thereafter use the Studio workspace copy of the sample to run and test it, even when running from the command prompt.

Using the workspace copy of the sample avoids permission problems. The default workspace location for this sample is:

    studio-workspace/sample_adapter_embedded_reuters-rmds-sub

See Default Installation Directories for the default location of `studio-workspace` on your system.
