You can run JES2 in a variety of processing configurations that range from a single base control program with a single JES2 that is completely isolated from other processing systems, to one that is a part of a worldwide processing network. The choice of configuration complexity is yours and generally is a dynamic one that grows as your business needs grow. The following options are basic JES2 configurations:

• Single-processor
• Multiple-system (multi-access spool)
• Poly-JES
• Remote job entry (RJE)
• Network job entry (NJE)
