This IBM Redpaper provides insights into JES2 performance and includes tips on how to monitor and tune your environment. It discusses the key components of the JES2 infrastructure in the context of performance goals. The content provides guidelines but does not offer clear cut recommendations. It is assumed that readers of this paper have the technical understanding and knowledge to manage an existing JES2 environment.
This paper discusses JES2 processor utilization, checkpoint and spool considerations, workload manager (WLM) managed initiators, scalability, command processing, and identifying issues with performance degradation. It also discusses performance tools that are available for analyzing performance-related data.
