JAVA environment variables

Java™ environment variables are global system variables that store system-wide values. To install IBM® EMM products, ensure that your machine has a Java Runtime Environment (JRE) version 1.6 or above.

Note: The JAVA_HOME environment variable is not required for installing IBM EMM products, but if it is present, it must be the 1.6 version of the Sun JRE.

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 IBM EMM 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 IBM EMM installers use the JRE bundled with the installers.

You can reset the environment variable after installation is complete.
