For a fast-track start to a career in z/OS systems programming, this is the course for you.
In addition to providing a solid knowledge of z/OS, this course also teaches how to set up and customize a JES2 system and how to work with DFSMS. The use of SMP/E for applying maintenance is covered. Students will learn how to use HCD panels to define I/O configurations. The Workload Manager (WLM) is covered, and students are also introduced to dump diagnostics.
This course is available 'on demand' (minimum 2 students) for public presentations or for exclusive one-company presentations.

What you will learn

Apr 06, 2021 If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available. If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. Link (,))))),)),).
