Activiti is a BPMN automation tool that makes communication between business analyst and the developers easy. Activiti has a web-based graphical interface for business analysts to prepare workflows that can be enhanced by developers adding Java code using an Eclipse plugin. It has a lightweight engine that can be embedded in Java applications to deploy the workflow and an explorer for deploying the process definitions online. Activiti also has a REST interface.

Activiti uses an in-memory database by default. Installation requires Java and servlet container like Tomcat. I have created a puppet script to automate activity installation in a virtual machine. The script installs activity Explorer and the REST interface with the mySQL database. if you want to connect to an external database you can make the necessary changes in the properties file within the code folder.

Installation instructions for Activiti

There are ways of creating a virtual Linux machine in your laptop (Mac and Windows). Virtualization leaves your operating system untouched, and the virtual machine can be removed without a trace after use. Without further ado, you can install this in 5 easy steps using my puppet script.

1. Install VirtualBox.
2. Install Vagrant.
3. Download and extract the zip file below to any folder.

RM1

4. Windows users double-click run.bat. Mac users run the following command from the download folder.
(The script takes approximately 10 minutes to setup the machine. However, no response is needed from your part. An internet connection is required.)
5. Access in your browser:

  • Access Activiti at http://localhost:8001/activiti-explorer
  • Access REST interface at http://localhost:8001/activiti-rest/services

To stop the machine on windows, use stop.bat and on Mac:

You can restart the machine as step 4 above. Restarting the machine does not require an internet connection.

If you want to destroy (uninstall) the virtual machine, use the following command in the script folder.

Feel free to fork and improve this script on GitHub. Pull-requests are welcome. Join E-Health on GitHub if you want direct write access to the repository.

Getting your Laptop ready for eHealth

OSCAR EMR and OpenMRS EHR
Image credit USDA @ Flikr (Image altered and text added)

EMRs and EHRs are of vital importance to health informatics students. Though there are several popular open-source products such as OSCAR EMR, installing them on your laptop can be cumbersome.They are designed for server installations with several prerequisites such as a backend database and a servlet container such as Tomcat. Though OSCAR EMR has an old Windows version, it has been marked as deprecated. If you are not a Linux geek, here is how you can install an EMR (OSCAR), an EHR (OpenMRS) and the popular statistical package R with R-Studio server. That is everything you need for your eHealth sojourn!

Installation instructions

There are ways of creating a virtual Linux machine in your laptop (Mac and Windows). Virtualization leaves your operating system untouched, and the virtual machine can be removed without a trace after use. Without further ado, you can install this in 5 easy steps using my puppet script. Obviously, this is for testing only and not for production.

1. Install VirtualBox.
2. Install Vagrant.
3. Download and extract the zip file below to any folder.

GitHub v1.1.0

This is the first public release

4. Windows users double-click run.bat. Mac users run the following command from the download folder.
(The script takes approximately 30 minutes to setup the machine. However, no response is needed from your part. An internet connection is required.)
5. Access in your browser:

To stop the machine on windows, use stop.bat and on Mac:

You can restart the machine as step 4 above. Restarting the machine does not require an internet connection.

If you want to destroy (uninstall) the virtual machine, use the following command in the script folder.

My puppet script is open-source. Feel free to fork and improve the script. Pull-requests are welcome. Join E-Health on GitHub if you want direct write access to the repository.
