This sample demonstrates the use of the TIBCO StreamBase® Adapter for ICAP/EBS Live XML.
Note
To use this sample, you will need to obtain access to a valid EBS Live XML market data server.
-
In the Package Explorer, double-click
EBSLiveXMLSample.sbapp
. -
Select the adapter icon to open the Properties view for the adapter.
-
Select the Adapter Properties tab and enter the Server Hostname and Port Number of the EBS Live XML server to which you have access.
-
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 connectivity to your EBS Live server is configured correctly, look for tuples emitted on the
IncomingMessages
stream indicating that market data is flowing. -
In the Manual Input view, select the
AdapterCommands
stream. Enterdisconnect
in thecommand
field. Click and observe that tuples stop flowing from theIncomingMessages
stream. Also observe that a message has been printed to the console to indicate the adapters has disconnected from the EBS Live server. -
In the Manual Input view, select the
AdapterCommands
stream again and enterconnect
in thecommand
field. Click and observe that tuples start flowing again from theIncomingMessages
stream. -
When done, press F9 or click the Stop Running Application button.
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.
-
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 EBSLiveXMLSample.sbapp
-
In window 2, type:
sbc dequeue -v
This window displays the tuples dequeued from the adapter's output port.
-
In window 3, disconnect from the EBS Live server:
echo disconnect | sbc enqueue AdapterCommands
-
Observe in window 2 that Tuples stop flowing from the
IncomingMessages
stream. A message is issued in window 1 to indicate the adapter has disconnected from the EBS Live server. -
In window 3, reconnect to the EBS Live server:
echo connect | sbc enqueue AdapterCommands
-
Observe in window 2 that Tuples start flowing again from the
IncomingMessages
stream. A message is issued in window 1 to indicate the adapter has reconnected to the EBS Live server. -
In window 3, type the following command to terminate the server and dequeuer:
sbadmin shutdown
In StreamBase Studio, import this sample with the following steps:
-
From the top menu, click
→ . -
Select this sample from the Embedded Input Adapters list.
-
Click OK.
StreamBase Studio creates a project for this sample.
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_ebslivexml
See Default Installation Directories for the default location of studio-workspace
on your system.
In the default TIBCO StreamBase installation, this sample's files are initially installed in:
streambase-install-dir
/sample/ebslivexml
See Default Installation Directories for the default location of studio-workspace
on your system.
