Resources become scarce when the system load is not evenly spread out across the system landscape, especially when high load jobs are submitted without control. SAP CPS comes with several ways to spread the load out across systems. Every SAP AS that is allowed to run jobs controlled by SAP CPS has its process server and queue created as soon as the connection is configured. You can use queues to spread the load over multiple process servers by attaching the process servers that can run the jobs to queues. Using Resources, jobs can be directed to specific process servers that serve the queue.
