This topic describes how to run the TIBCO ActiveSpaces® operator sample application, which illustrates how to use the operators with an ActivesSpaces data grid.
For more information on this operator, see Using the TIBCO ActiveSpaces Operators.
This sample includes a number of ActiveSpaces operators, which by default connect to
an ActiveSpaces data grid named
TestGrid on localhost.
The sample data grid supplied with the ActiveSpaces installation is assumed to be
running on localhost already, by executing
%TIBDG_ROOT%/samples/scripts/as-start.bat on Windows systems or the
corresponding script on other platforms. To connect to other ActiveSpaces servers,
edit the sample's
src/main/configurations/ActiveSpaces.conf file appropriately.
Once connected, you can use the sample to put rows into and retrieve rows from the
sample table (named
t1) using the various ActiveSpaces
In StreamBase Studio, import this sample with the following steps:
From the top-level menu, select> .
activespto narrow the list of options.
Select TIBCO ActiveSpaces Operators from the Other TIBCO Product Connectivity category.
Before running you must configure the project to locate and load the ActiveSpaces libraries. Open
src/main/configurations/engine.confand adjust paths based on your own install locations for TIBCO ActiveSpaces and TIBCO FTL.
Make sure the data grid that ships as an ActiveSpaces sample is up and running on the local machine (or, if running it on another machine, edit
ActiveSpaces.confto point the data grid definition to the right IP address). You can launch the data grid by running
In the Project Explorer view, open the sample you just loaded.

activespaces.sbappfile and click the Run button. This opens the SB Test/Debug perspective and starts the module.
Once the application has started, the ActiveSpaces Control operator connects to the data grid then sends a
Connectedtuple to the application.
In the Manual Input view, select the
Enter the following values:
Clickand observe that the
PutResultsoutput stream received a tuple with its
inputfield set to the given command tuple and its
rowfield set to null, indicating that the operation succeeded and finished.
Still in the Manual Input view, select the
GetCmdstream and enter
1as the value for the key field, then click . This fetches the row with key
1and emit it on the GetResults output stream, followed by a marker tuple (row = null) to indicate the operation finished executing.
You may similarly send arbitrary queries to a table (for example,
SELECT * FROM t1 WHERE key > 0) using the QueryCmd stream and remove rows using the DeleteCmd stream. Of note is the ControlCmd stream which allows you to send control commands to, for example, disconnect from the data grid. Finally, if you have defined your data grid connection to be transacted (by adding
<setting name="transacted-session" val="true"/>to the definition) you can commit or rollback your data grid operations using the
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:
