Sonar runs on any operating system that support Java and Maven. Those two pieces of software need to be installed first :

 Sonar requires a relational database for storage of measures data. Sonar supports :

Sonar ships pre-configured with the Derby embedded database, which is suitable for evaluation purposes. Although using the Derby database gives access to a fully functional version, we do not test any version migration on it. Therefore, before deploying to a production environment, we strongly recommend that you connect Sonar to an enterprise database.

The Sonar web server requires 500Mo of RAM to run efficiently.
In terms of data space and as an indication, on Nemo the public instance of Sonar, 2Go of data space are used to analyze more than 6 million LOC with an history of 2 years. For every 1'000 LOC to analyze the database stores 350 Ko of data space. Nemo is currently running on a Amazon EC2 small instance.

  • Firefox 2.x and 3.x
