In this section, you will learn how to install and setup the foundations of your geOrchestra SDI, according to the recommended architecture: architecture

Compatibility notes

This guide assumes the OS is Debian's latest stable (Buster) and Tomcat 9 is deployed.

geOrchestra 17.12 has been tested with tomcat 8 on Debian 9 (Stretch).

geOrchestra 16.12 has been tested on Debian 8 (Jessie) with Tomcat 8.

geOrchestra >= 15.12 deprecates tomcat6 and java 6.

geOrchestra 15.06 has been tested on Debian 8 with Tomcat 6, 7 and 8.
