On Windows, the installation program automatically installs and configures the correct level of Java Runtime Environment (JRE 1.4.1) required by DB2 OLAP Server and DB2 OLAP Integration Server, so no more action is needed. The JRE is required to support features such as custom-defined macros and custom-defined functions.
However, the JRE is set up so that only DB2 OLAP Server and DB2 OLAP Integration Server can use it. No other program can access that JRE unless you update the PATH system variable.
To allow other applications to access the JRE that is installed with DB2 OLAP Server, you need to add this variable to your PATH statement:
%JREHOME%\bin
For example, you can set your PATH to the following value:
PATH=%JREHOME%\bin;%PATH%
After the Java components are installed on your system, you can use the Java Development Kit (JDK) installed with this product to create your own custom-defined macros and custom-defined functions.
