Set Up

To create a full Stardust Runtime Environment on Amazon Web Services EC2 Infrastructure,


You will be asked to login with an existing Amazon account or to register for one:


Launch with one 1-Click will launch the Stardust Runtime on your EC2 Instance Type of choice:


The AWS Virtual Machine Image (AMI) is configured to run on all Instance Types including the Standard Micro (t1.micro) type and your choice depends entirely on the expected load profile. For first experiments the Standard Micro is definitely sufficient.

Please consider that although there are no charges for Stardust, Amazon charges you for most of the EC2 configurations.

Select your data center region of choice - the Stardust AMI is available for all AWS data center regions:


You will be prompted to confirm that you do not want to create a Key Pair:


You only need this if you intend to login to the EC2 instance and modify the setup, which is needed e.g. for

  • troubleshooting (see below),
  • tuning for larger deployments or
  • adding application specific Java byte code.

Hence, we recommend to generate Key Pair and and use it.

If you just intend to run and configure Stardust via the Stardust Web Portal, there is no need to create a Key Pair and you can consider the installation a block box.


After you have launched your instance and the instance is available, lookup the Public DNS Name for the instance and login via

http://<Public DNS Name>:8080/stardust-standard


  • User: motu
  • Password: motu

This is the Stardust root user. Make sure that you can change the password later.

Use the Stardust Portal as described in the respective chapter of the Stardust documentation.

Process Model Creation and Deployment

If you are keen to start playing and do not bother to create a Process Model at this point pick one of the sample process models from Git e.g. the Car Rental Example (right-click the link before and save the file) and just upload and deploy under Administration > Model Management


More details on model deployment can be found in the corresponding chapter of the documentation.

If you intend to create your own Process Models, you can either use the Browser Modeler which is immediately available in the Stardust Portal of your Amazon EC2 Instance or use the Stardust Eclipse Modeler - which requires you to download Eclipse and install Stardust.

User Creation and Role Assignment

Do not forget to create users and assign to roles so that you can start processes and perform activities in your process.


Below a few things which might help you if you are facing problems. If nothing helps, post in the Stardust Forum. You very likely find help there.

Tomcat Out of Memory Issue

Currently, the Tomcat installation on the Stardust Image is not configured with the appropriate memory size for its Java VM. To address this issue, login to your EC2 Instance using your Key Pair and add the following

set CATALINA_OPTS=%CATALINA_OPTS% -Dtrue=true -Xms1200m -Xmx1200m -XX:NewSize=300m -XX:MaxNewSize=300m -XX:PermSize=256m -XX:+UseTLAB

at the beginning of /home/ec2-user/apache-tomcat-6.0.32/bin/catalina.sh.

This problem will be addressed soon on the original image.

Other Trouble Shooting

If something totally unexpected happens in the Portal, try a reboot of your EC2 instance after making sure that no other user is working on the system.
