Objectives

The Multiple Virtual Storage (MVS) operating system is well known as the IBM flagship of operating systems. It was first included in the OS/390 family, and actually it is part of the z/OS product.

During this course, participants:

  • get an insight in the meaning of MVS as operating system;
  • understand the basic concepts of z/OS and its subsystems;
  • learn to interpret the MVS features in the context of z/OS;
  • become familiar with the z/OS environment;
  • get an insight in the evolution of MVS to z/OS.

Main topics

  • Hardware:

CPU • storage • channel subsystem • peripheral devices • network • multi-processing • LPAR • sysplex

  • Concept of MVS:

virtual and real storage • paging • address spaces • system initialisation (IPL)

Evolution of MVS to z/OS

  • Task management • storage management • resource and workload management
  • Data management:

access methods • data organisation • the catalog • storage management subsystem (SMS)

  • JES and job management
  • Recovery and monitoring
  • z/OS subsystems:

user interaction (TSO and ISPF, UNIX shell) • security (RACF) • data communication monitors • database management systems • SDSF • Web based access (HTTP, WebSphere Application Server, MQ) • ...
