Check for a JAVA_HOME environment variable

If you have a JAVA_HOME environment variable defined on the machine where you are installing an IBM® Unica® product, verify that it is pointing to version 1.6 of the Sun JRE.

This environment variable is not required for installing IBM® Unica® products, but if it is present, it must point to the 1.6 version of the Sun JRE.

If you have a JAVA_HOME environment variable, and it points to an incorrect JRE, then you must unset the JAVA_HOME variable before you run the IBM® Unica® installers. You can do this as follows.

Windows™: In a command window, enter

set JAVA_HOME=leave empty and press return key

*NIX-type systems: In the terminal, enter

export JAVA_HOME=leave empty and press return key

After the environment variable is unset, the IBM® Unica® installers use the JRE bundled with the installers.

You can reset the environment variable when installation is complete.
