Running the Java code on the Parallel Engine

Your Java™ code is invoked by one or more Java Virtual Machine (Java VM) instances in the InfoSphere® DataStage® parallel engine environment. The conductor is an initial DataStage process that creates a single Java VM instance and loads your Java code and other Java-based Connector stage code in your job. The processors on the player nodes are forked per each stage in the job and are the actual processes that are associated with stages. A Java VM instance is created for each player process that is associated with your Java Integration stage where your Java code runs.
