Setting the JAVA_HOME environment variable

Set the JAVA_HOME environment variable to point to the directory where the Java™ runtime environment (JRE) is installed on your administrative computer.
The following variable is used in path names in this topic:
RATIONAL_COMMON
Directory where Rational common files are installed

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.

  1. On your Windows® desktop, right-click My Computer and select Properties.
  2. Click the Advanced tab and then click Environment Variables.
  3. In the System variables area click New.
  4. Enter JAVA_HOME in the Variable name field. Enter the pathname of the JRE installation directory in the Variable value field. For example: C:\%RATIONAL_COMMON%\Java\jre. Click OK.
  5. Click OK.

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.
