This course and the associated Part 2 course together form the essential core of the z/OS education curriculum for z/OS Systems Programmers. By attending both components attendees will gain an in-depth insight into the fundamental structure of MVS (now z/OS), enabling further study in areas such as debugging, performance, installation and customisation of the operating system.<br>This course concentrates on laying the ground rules of z/OS in terms of architecture, storage management, as well as the major control blocks and how to interpret them. The course also introduces the major components found in z Systems environments.<br><br>This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

A good working understanding of the z/OS environment, from a technician's perspective.

  • describe the architectural principles governing CPU, Storage and I/O
  • identify the state of a CPU and describe potential problem scenerios
  • use IPCS and the debugging guides
  • describe the principles of Virtual Storage
  • describe the purpose of AMODE and RMODE
  • describe a page fault and its consequences
  • set up a flexible paging/swapping subsystem
  • explain how dataspaces and hiperspaces work
  • describe how an IPL works
  • isolate problems during an IPL
  • explain the concept of authorised programs.

z/OS System Anatomy Part 1 - z Architecture Training Course in Finland

Finland is a country located in northern Europe. Helsinki is the capital and largest city of the country. The majority of the people are Finns but there is also a small Lapp population in Lapland, where the country is famous for the Northern Lights. Finland's national languages are Finnish and Swedish.

Known for its vast forests, lakes, and natural beauty, Finland is one of the world's largest producers of forest products, such as paper, pulp, and lumber. One of the world's largest sea fortresses Suomenlinna, Rovaniemi with the "White Nights", dogsled safaris and of course the Northern Lights are what makes Finland so popular for tourists. Finland is one of the best places in the world to see the Northern Lights and attracts millions of tourists during its seasons.

Finland is home to a thriving technology industry and is widely recognized as one of the world's leading technology hubs. Companies such as Nokia and Rovio (creator of the popular game Angry Birds) are based in Finland. Some of the key factors that have contributed to Finland's success in technology include; strong investment in research and development, a highly educated workforce and fundings.

Finland has a strong educational system, and is widely regarded as one of the world's most literate countries. In fact, Finland's literacy rate is one of the highest in the world, and its students consistently perform well in international tests of math and reading ability.

Also, as a pioneer in environmental sustainability, Finland is known for its efforts to reduce its carbon footprint and promote clean energy. This Nordic country is also famous for its unique and distinctive cultural heritage, including its traditional folk music and its elaborate traditional costumes.

Helsinki, Finland's capital city, is the country's business center. Helsinki is Finland's largest city, and it is home to many of the country's major corporations and organizations, including many of the country's leading technology firms. The city is also a commercial, trade, and financial center, as well as one of the busiest ports in the Nordic region.
