z/OS System Services Structure

This course introduces the structure and control blocks of the z/OS BCP and system services. It prepares the new z/OS programmer to identify potential bottlenecks and performance problems, perform initial error symptom collection, and identify z/OS system customization opportunities and requirements. This course also provides the initial information needed for further training in specialized areas such as system measurement and tuning and identifying system problems.

Issues

Explain the MVS functions and control blocks necessary to handle the task in a multitasking and multiprocessing environment
Describe the software and hardware functions that enable a program to interact with programs running in other address spaces, use data in other address spaces, and use data in data spaces
Track the flow of input/output operations from the initial request in the application program to the completion of the data transfer
Identify control blocks that describe the current state of the input/output request
Describing the functions of virtual, real and auxiliary storage managers in z/OS BCP
Describe the functions performed by the Recovery Termination Manager and recovery management components to minimize the impact of failures and improve error correction
Selecting the appropriate IBM publication for further technical information (SRL, technical bulletins, self-study and other z/OS courses)
Describe the services provided by extended inter-system services (XES)
Define and explain the purpose of cache structures, lists and locks
Planning the implementation of STAR global resource serialization in the environment

Who is this training for?

The primary audience for this intermediate course is z/OS developers who are new to installing, customizing, measuring and tuning z/OS or identifying problems

Subsystem programmers will also benefit from this class

Prerequisites

To describe the following features of the z/OS BCP (MVS):
