This sample demonstrates the use of the TIBCO StreamBase® Adapter for BM&FBovespa UMDF. See BM&FBovespa UMDF Input Adapter for details on the use and structure of this adapter.
This sample use one instance of the UMDF Input Adapter to connect to the BM&FBOVESPA UMDF market feed and provide market data. In order to run this sample, you must have access to one of BM&FBOVESPA's UMDF feeds for the adapter to use.
Once the application has started, you can use the adapter to subscribe to one or more instruments to obtain instrument definition, initial snapshot, incremental updates and other FAST messages for those instruments as they are issued by the market feed.
In StreamBase Studio, import this sample with the following steps:
From the top-level menu, select> .
UMDF Input adapterfrom the StreamBase Market Data Adapters category.
StreamBase Studio creates a single project containing the sample files.
In the Project Explorer view, double-click to open the sample application,
channelDefinitions.xmlfile to input the proper IP addresses and ports supplied to your company by BM&FBOVESPA to access the UMDF data feeds. See BM&FBovespa UMDF Input Adapter for details on editing this file.
Be sure to obtain an up-to-date version of the UMDF FAST templates definition file (called
templates-UMDF.xmlin the sample) from BM&FBOVESPA and place it in the sample's top-level directory. Make sure the adapter's FAST Template File property points to this file.
Click the Run button. This opens the SB Test/Debug perspective and starts the module.
In the Manual Input view, select the Subscriptions stream. Enter the following values and click:
MyChannelis the value specified in the
<channel id="MyChannel">attribute, and
MySymbolis the name of a valid instrument handled by this UMDF feed.
After you have sent the command, the adapter connects to the configured Instrument Definition stream and obtains the definition for the specified symbol. Once received, the adapter issues a tuple on the InstrumentDefinitions output port that contains the contents of the received FAST message.
This step happens only the first time you subscribe to this symbol in the lifetime of the application. If you later unsubscribe and resubscribe, this tuple is not generated.
The adapter next sends a tuple on the Events port to indicate the subscription to the symbol has succeeded.
The adapter connects to the configured UMDF Recovery stream to obtain the current state of the book for this instrument. Once the snapshot is obtained, a tuple is emitted on the Snapshots output port with the information.
At this point the adapter starts emitting tuples on the IncrementalRefreshes port as updates become available.
You can also periodically observe messages of type News and others being generated on the OtherMessages port as they are received.
When done, press F9 or click the Terminate EventFlow Fragment button.
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.
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:
