Book description
Today, mainframe computers play a central role in the daily
operations of most of the world’s largest corporations. While
other forms of computing are used in business in various
capacities, the mainframe occupies a prominent place in
today’s e-business environment. In banking, finance, health
care, insurance, utilities, government, and a multitude of other
public and private enterprises, the mainframe computer continues to
provide the foundation of large-scale computing to modern
business.
The reasons for mainframe use are many, but generally fall into one
or more of the following categories: capacity, scalability,
integrity and security, availability, access to large amounts of
data, system management, and autonomic capabilities. This IBM
Redbooks publication is designed for readers who already possess a
basic knowledge of mainframe computing, but need a clearer
understanding of how these concepts relate to mainframe planning,
implementation, and operation. For readers who need more
introductory information about mainframe concepts, usage, and
architecture, we recommend that you complete Introduction to the
New Mainframe: z/OS Basics, SG24-6366, prior to starting this book.
And for more detailed information about z/OS programming topics,
refer to the 11-volume book series ABCs of z/OS System
Programming.
