This chapter describes how to enable DB2 OLAP Server and DB2 OLAP Integration Server to work with the Java Runtime Environment (JRE) and the Java API for XML Parsing (JAXP).
DB2 OLAP Server v8.1 requires Java for custom-defined macros and custom-defined functions. Both the JRE and the JAXP must be installed on machines running the server component. This includes the Java Virtual Machine (JVM), which is a component of the JRE. If you have already installed a supported version of the JRE, you do not have to reinstall the JRE. However, you must verify that JAXP component is installed, set the JVMMODULELOCATION parameter of the essbase.cfg file, and set the environment variables.
After the Java components are installed on your system, you can use a Java Development Kit (JDK) of your choice to create your own custom-defined macros and custom-defined functions. A JDK is not supplied with DB2 OLAP Server or DB2 OLAP Integration Server.
