If the parallel engine is installed on a computer that runs Microsoft Windows Server, Standard or Enterprise edition, increase the noninteractive desktop heap size to ensure that a sufficient number of processes can be created and run concurrently.
IBM® InfoSphere® DataStage® processes are created in a specific desktop heap. Each process consumes a small amount of memory from the desktop heap. If you expect to run many InfoSphere DataStage jobs concurrently, increase the size of the noninteractive desktop heap to allow more processes to be created and run concurrently.
