z/OS System Anatomy Part1 - zArchitecture [MSF1]

This course and its associated Part 2 together form the core course of the z/OS education curriculum. By attending both components, attendees will gain a solid foundation in the fundamental structure of MVS, enabling further study in areas such as debugging, performance, installation, and customization of the operating system.  This course concentrates on laying the ground rules of z/OS in terms of architecture, storage management, as well as major control blocks and how to interpret them. The course also introduces the major components found in z Systems environments

This course provides attendees with an effective and systematic approach to z/OS problem diagnosis. In this course, the z/OS software environment is examined by looking at the Recovery Termination Manager (RTM) – the ‘cleaning-up’ function of MVS – and its ABEND-concept. All the different reports that come out of a z/OS system, in conjunction with failures (messages, dumps, traces, etc.), are also discussed. System ABENDs, and how you can analyze the information coming out of the system when they occur, is also covered. Attendees will learn how to identify system problems promptly, in order to provide greater system availability. The course focuses on a debugging methodology using IPCS. Practical workshops provide an opportunity to learn to debug system problems in realistic situations.

• Understand the concept of a User ABEND
• Analyze User ABEND situations
• Resolve User ABEND situations
• Report problems and communicate with applications personnel and systems programmers
• Understand what the Recovery Termination Manager (RTM) does when programs fail
• Understand the concept of an ABEND
•  Analyze ABEND-situations
• Use the appropriate diagnostic procedure for each type of dump
• Identify the failing operating system component in standalone and SVC dumps
• Use various operating system data-gathering facilities such as system traces, LOGREC, and SLIP
• Locate information in various manuals that is critical to problem resolution
• Use the tools available in order to resolve common system abends without Dumps

To benefit from this course, participants need the ability to read Assembler code, familiarity with z/OS internal operations & data areas, including the concept of control block chaining. These prerequisites can be met by completing the courses Using z/OS Assembler [AS], z/OS System Anatomy Part 1 [MSF1] & z/OS System Anatomy Part 2 [MSF2]

This course describes & explains what can go wrong in an IBM z Systems environment, & what you can do about it as an operator or systems programmer. It looks at failure situations from many points of view: the physical computer rooms, hardware problems & the software environment. The software environment is further examined by looking at the Recovery Termination Manager (RTM)-the "cleaning-up” function of z/OS & its ABEND-concept. All the different reports that come out of a z/OS system in conjunction with failures (messages, dumps, traces, etc.) are also discussed. The most common reasons for system ABENDs (& how you can analyze the information coming out of the system when they occur) are also covered.
