To use the Global Security Kit (GSKit) iKeyMan utility, which lets you create a key database for storing SSL certificates, set the JAVA_HOME environment variable to point to the directory where the Java runtime environment (JRE) is installed on your administrative computer. You must use the JRE that ClearQuest provides. By default, the Rational ClearQuest® installation procedure installs the JRE in the directory %RATIONAL_COMMON%\Java\jre.
Alternatively, you can temporarily set the JAVA_HOME environment variable by setting it within a Windows command prompt window. You can then run the GSKit iKeyMan utility from within the command prompt window.
