Parallel job execution

Parallel job execution can improve the performance of data-intensive operations that are associated with very large database environments.

Parallel jobs run on servers that are configured as symmetric multiprocessing systems (SMPs), massively parallel processing systems (MPPs), or on cluster systems. The performance is improved because the job processing can be split among many CPUs on a single system.

Parallel job execution helps systems scale in performance by making optimal use of hardware resources. If your system's CPUs and disk controllers are already heavily loaded, you need to lighten the system's load or increase the hardware resources before using parallel execution to improve performance.

For more information about creating and running the jobs, see the InfoSphere® Information Server information center.
