Installation of z/OS and other software products

z/OS system installation and maintenance

To install means to perform the tasks necessary to make the system operational, starting with a decision to either install for the first time or upgrade, and ending when the system is ready for production.

An installation plan is a record of the actions you need to take to install z/OS®.

  • z/OS base elements and optional features
    The z/OS operating system consists of base elements and optional features.
  • Methods of installing z/OS
    Several IBM® packages are available for installing z/OS. Some are entitled with the product (as part of your z/OS license, at no additional charge), while others are available for an additional fee.
  • Typical organization of IBM and other software in storage
    Your installation's operating system environment consists of several different types of code and data– some supplied by IBM, some by other vendors, or some by your company's programmers– all of which combine to make your z/OS system unique. Once these software products and applications have been organized and stored, system programmers spend much of their time planning when to install updates or new software products, how to test them, and when to move them into production systems without adversely affecting workloads.
