Introduction to z/OS and Major Subsystems

This course introduces operating system and data processing concepts in the context of large system (or Enterprise) computing using a combination of active learning exercises and passive learning presentations. The course context covers modern hardware, operating system, and middleware functions and features. This includes hardware concepts such as virtualization, logical partitioning, multi-processing and high performance I/O. The operating system concepts covered include workload management, (batch and transactional), dispatching , job control language, security, networking and other operating system functions. A brief introduction to z/OS UNIX is included as well. The course concludes with an overview of key middleware (transaction and database managers as well as messaging software) and their contribution to an overall hardware/software configuration needed to process enterprise workloads.
