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.

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.
