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).

Note: To know the compatible JRE verions or JDK versions, see the Recommended Software Environments and Minimum System Requirements.

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.
