The default values for Global Variables may be overridden in your BusinessEvents Studio Run Configuration. This can be useful for local tests, where you are debugging your application from Studio, as opposed to deploying it using TIBCO Administrator or TIBCO Enterprise Administrator (TEA).

Consider the BusinessEvents FraudDetection example, provided under $BE_HOME/examples/standard/FraudDetection/. This example uses a HTTP connection configuration under SharedResources/HTTPConnection.sharedhttp. This HTTP connection defines the http Port value to set for this application. You may set this value using a Global Variable defined in your project:



Here, we have defined a Global Variable group named 'HTTP', and added a Global Variable under that group, named 'HTTP_PORT'. The default value set in the project is 8108. This Global Variable is then used in the HTTP Connection configuration, as shown above (%%HTTP/HTTP_PORT%%).

To override this value in a Studio Run Configuration, use the -V option under the 'VM Arguments' section of the Run Configuration:



This will override the default value (8103) and set the http Port to 8113 instead (-VHTTP/HTTP_PORT=8113).
 

This article demonstrates how to override the values of Global Variables in a BusinessEvents Studio Run Configuration. This can be useful for local tests, and may prevent the need to manage multiple CDD or Supplementary Properties files.
