Understanding the BIRT iHub installation environment
The following sections provide supplementary information about the BIRT iHub installation environment.
Running different releases on the same machine
A BIRT iHub 3 installation cannot coexist on the same machine with an earlier release of BIRT iHub or iServer.
Understanding the Java Runtime Environment
The BIRT iHub installation program installs Java Runtime Environment 1.8. By default, BIRT iHub uses this JRE. If you want to use a different JRE, you must set the appropriate environment variables in the configuration files used by BIRT iHub Visualization Platform and System Console.
