To install the latest OpenRules Decision Manager on your computer, you need to execute “install.bat” from “openrules.samples/openrules.config” – just double-click on this file from your File Manager.

You need to have Internet connection as the installation will download different related products freely available for downloads. The installation may take up to 1-2 minutes based on your connection speed displaying all downloadable files at the “black” screen. There should be no red messages and the successful installation will show at the end

The main difference with Windows is that to start any execution, you will use scripts like “install”, “clean”, “run” instead of “install.bat”, “clean.bat”, “run.bat”.

Open a Terminal window and go to the unzipped folder “openrules.samples” and then to the sub-folder “openrules.config”. Enter commands:

    >chmod +x install

Build and Run Decision Models. You can build and test a decision model by a simple double-click on the file “run.bat“.  For Mac or Linux, use the script-file “run“. When you try it for the first time, you may need to confirm that it’s safe to execute this script.

If you make any changes in your Excel tables or configuration files, it will automatically re-build the model before running its tests. If it finds any errors, it will display them using the business terms pointing to the corresponding places in your Excel files.

After the successful build, “run.bat” will test your model against test-cases described in the file “Test.xls”.  When you execute the decision model, the Decision Manager produces a user-friendly execution protocol and explanation reports in the HTML format in the generated folder “report“. Some decision models (e.g. HelloJava) use data instances created not in Excel but using the existing Java classes. 

You may do all work within the folder “openrules.samples” using the standard File Manager – no technical knowledge is required. Technical people may import all projects into their favorite IDE such as Eclipse.

You can use your OpenRules Decision Manager to create your own decision services and deploy them on-premise or on cloud using your preferable deployment options: AWS Lambda functions, RESTful Web Services, or Docker images. Wherever you deploy your decision model, every execution of this service will be reported to the AWS Marketplace metering service. Based on your actual number of executions and the above Pricing, AWS Marketplace will provide you with accurate monthly bills. All charges will go through AWS and you have an option to cancel your subscription at anytime.
