# functionexecution example This example illustrates how to execute server side java functions.

Prerequisites

• Install Apache Geode
• Build and install Apache Geode Native
• Apache Geode Native examples, built and installed
• Set GEODE_HOME to the install directory of Apache Geode

Running

1. From a command shell, set the current directory to the functionexecution directory in your example workspace.

   $ cd workspace/examples/build/dotnet/functionexecution
   

2. Run the startserver.ps1 script to start the Geode cluster with authentication and create a region.

   For Windows cmd:

   $ powershell.exe -File startserver.ps1
   

   For Windows Powershell:

   $ startserver.ps1
   

3. Execute dotnet-functionexecution.exe, expect the following output:

   rtimmons = Robert Timmons
   scharles = Sylvia Charles
   Function Execution Results:
      Count = 1
      value = Robert Timmons
      value = Sylvia Charles
   

4. Run the stopserver.ps1 script to gracefully shutdown the Geode cluster.

   For Windows cmd:

   $ powershell.exe -File stopserver.ps1
   

   For Windows Powershell:

   $ stopserver.ps1
