z/OS subsystems

The IBM mainframe environment is driven and controlled by the z/OS operating system. However, applications are using different subsystems, designed for specific purposes. During this course participants learn to describe the functions and main components of the following important z/OS subsystems:

In addition, participants will get an overview of the management aspects for all these subsystems, and will be able to describe the safety- and integrity-aspects.

Schedule

No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.

Intended for

Everyone in the systems department who wants a general introduction to the z/OS subsystems. Especially for DP managers, system programmers, system analysts and operators.

Background

A basic mainframe background is required (see Mainframe computing introduction).

Main topics

Terminal control • dataset manipulation • error treatment • resource management • interprogram communication • monitors • development tools.

Communication between programs and database management systems and/or message queues.

System management: description of possible error situations • recovery and restart facilities • synchronisation and security • distributed CICS facilities • CICSPLEX

hierarchical structures • physical organisations of databases • the most important control blocks (DBD and PSB) • application interface DL/1 • secondary indexes and logical relations

tasks of the DC monitor • internal set-up • conversational versus non-conversational applications • synchronisation and security

what is an RDBMS • how do applications use Db2 (static vs dynamic, drivers) • Db2 system objects • Db2 from the OS system point of view (setup, address spaces, ...) • Db2 and security • distributed Db2, DDF, DRDA, Connect • Db2 family

Understand the position of USS within the OS • USS as a Unix shell • USS user interfaces • HFS • Irish commands • security • USS and TSO, USS and JCL • monitor USS activity • software that depends on USS: TCPIP, Web Server, JVM, WebSphere Application Server

Concepts of queuing • distributed topology • WMQ objects, communication, shared queues, clusters • WMQ from the OS system point of view (setup, address spaces, ...) • MQ application behaviour • MQ bridges

WAS as a Java EE runtime • WAS administrative architecture and repository • application flow in the server • application deployment and maintenance • relationship with HTTP server, CICS, MQ, IMS, Db2 • WAS from the OS system point of view (setup, address spaces, ...) • WAS topologies for load balancing and availability
