The z/OS Architecture course examines the logical architecture of a z/OS system. It looks at the use and structure of the Program Status Word (PSW), the different types of interrupts handled by the system, and how they are invoked. It also describes the concepts and use of virtual storage and how it relates to address spaces within the system. Finally, it identifies the functions used by the System Resource Manager to balance and maximize system performance.
Technical support personnel and senior programmers who need to learn aspects of z/Architecture for use in planning, problem determination, and advanced programming techniques.
A good understanding of operational concepts or successful completion of Interskill's z/OS Concepts and Components course.
After completing this course the student should be able to:
- Identify the purposes of different bits within the PSW
- Identify the different interruption types
- List the functions performed by the supervisor
- Identify virtual storage components and their elements
- Recognize the method used to translate virtual addresses into real addresses
- Identify the names and purposes of the areas and regions within the z/OS address space
- List the functions performed by SRM in relation to balancing system loads
- Display and alter message processing facility settings
