Series: z/OS 2.4
z/OS – Concepts and Components
The z/OS Concepts and Components course describes the evolution of mainframe computing and provides descriptions of the major components that comprise today's z/OS environment. Details of general z/OS processing concepts are also provided.
z/OS – Initializing and Terminating the z/OS System
The Initializing and Terminating the z/OS System course describes what actions occur as part of a z/OS system initialization, and then delves into the system data sets and configuration libraries responsible for defining z/OS system characteristics. The final module in this course simulates a z/OS system start-up and shutdown, describing the most common commands and operator responses.
z/OS – Monitoring the z/OS System
This course introduces z/OS commands that can be used to display the status and attributes of various z/OS tasks and devices. An overview of system monitoring tools and facilities such as RMF, z/OSMF, traces and EREPS are also provided as well as a description on how SMF data is created and controlled. This course also discusses the need for message suppression and describes how this is achieved.
z/OS – Identifying z/OS System Problems
The Identifying z/OS System Problems course explores some of the processes, commands, and tools that are used in identifying system problems. It describes how common system problems are recognized, and the steps that can be taken to assist with problem resolution, including dumps and analyzing the catalog address space.
z/OS – Resolving z/OS System Problems
This course describes the processes and commands required to resolve common z/OS system problems. It also describes when cancel and force commands should be used and how to handle command flooding.
z/Architecture – Processing Workloads
The z/OS Architecture - Processing Workloads course describes how today's z/OS system processes workloads, focusing on the concepts of address spaces showing how they provide the environment under which tasks can run. You will look at the different types of CPUs that can be configured in a z/OS system and see how programs issue instructions to the CPU. Diving down deeper you will then look at the CPU chips themselves and view the components that comprise them, looking at their involvement in processing work. Finally, the major components that comprise the mainframe's I/O structure are presented to show how work moves throughout the z/OS environment.
z/Architecture – Memory, Address Spaces, and Virtual Storage
Processor storage, real storage, or central storage. Whatever you call it, it is the memory where z/OS programs and their data need to reside before they can be processed, and like other mainframe resources it can be virtualized. In this z/OS Architecture - Memory, Address Spaces and Virtual Storage course, you will see how the address spaces discussed in the previous course, access and free the memory they require to process work. You will also see how virtualization of this resource occurs, which for IT specialists will provide them with knowledge to troubleshoot memory-related issues.
z/OS – Advanced – Tips & Tricks
This course contains many z/OS-related tips, tricks, techniques, and best-practice items that you may find useful in your day-to-day activities. It covers several new areas of functionality associated with z/OS 2.3 and z/OS 2.4.
