JAVA environment variables
Java™ environment variables are global system variables that store system-wide values. To install Unica products, ensure that your machine has a Java™ Runtime Environment (JRE) version 1.8 or above.
If you have a JAVA_HOME environment variable, and it points to an incorrect JRE, you must unset the JAVA_HOME variable before you run the Unica installers. To unset JAVA_HOME variable:
- Windows™: In a command
window, enter
set JAVA_HOME=leave empty and press return key
- UNIX™ type systems: In the
terminal, enter
export JAVA_HOME=leave empty and press return key
After the environment variable is unset, the Unica installers use the JRE bundled with the installers.
You can reset the environment variable after installation is complete.
