Book Description
The system/38 differs from conventional machines in a number of ways. The most important differences are o A database management system is integrated with the operating system. All data files are data base files. o Main memory and auxiliary storage (disk) are treated as one unit. Inter alia, this means that not only programs but also data files are paged into and out of main me mory. o All objects must be addressed via a library and by name; also the libraries themselves (namely via QSYS). The user has no way of reaching physical addresses (which he can't find out anyway). o Large parts of the operating systems are in microcode. o There is no assembler language. The unique features of the S/38 make it necessary for the auditor to put in some effort to learn how the system works. Otherwise he is likely to misunderstand important aspects of the data processing performed on the system. Some knowledge is also required to use the system's fea tures effectively for obtaining an understanding of the system and performing compliance and substantive tests on it. 2. Hardware Characteristics 2.1. General Information The IBM S/38 is a general purpose data processing system designed to provide ease of use, reliability, and an inte grated database. The system has a unique architecture with an integrated relational data base design that supports interactive workstation applications as well as traditional batch applications.

Book Description
I began to write this book over twenty years ago. My purpose was to tell the true story about how IBM made too many companies successful by standing down rather than competing. As a Senior IBM Systems Engineer, I saw it all happen. The $ Trillion dollar PC marketplace is the biggest example of IBM's major losses. Yet, the PC was just one of many industry sub-segments over the years in which IBM failed miserably. We need more than ten fingers to count them all. This book tells all the great stories about how industries came into being and entrepreneurs often in their early twenties became billionaires. This book tells you which companies did the best; which regular guys became industry moguls; and who has the money today. Among other things, it tells us all who owes IBM the biggest thank you’s. This book in many ways is about Big Blue’s misgivings about being too successful in too many IT product areas. IBM Executives over the years from the CEO on down were all paid very well to manage all aspects of the company’s business. Unfortunately each and every CEO after the Watsons and T. Vincent Learson, focused on just one aspect of IBM – its mainframe business. So the IBM Chieftains lost just about every other opportunity including the PC. They simply handed very crafty “entrepreneurs,” the whole game. IBM created many industry billionaires simply by not watching its assets. Microsoft alone has four documented billionaires on its list which is topped by Bill Gates, the richest man in the world at $102 billion. Additionally, there are over 12,000 other Microsoft employees on the millionaire’s list. IBM paid for all of the zillionaires. In Chapter 1, I show each and every billionaire and a number of millionaires. I then go on in sixty-nine chapters to tell you the essence of the full Microsoft / IBM story along with many other stories of IBM squandering many other real business opportunities. These are enjoyable to read but hard to believe. You are going to love this book, designed by an IBM insider and told with respect for IBM and with the truth that all of these great stories deserve. You will not want to put this book down. Kelly not only gives the facts about the new billionaires; he also provides a history lesson about the entire industry that will capture your imagination. You’ll learn how all these billionaires got their money. The book begins with the introduction of the first computer and it takes you on a ride through all of the major events that occurred during each IBM CEO’s tenure. The story thus begins with Thomas Watson Sr, as CEO and continues chapter by chapter to the state of the computer industry today. Kelly does it all in 69 easy-to-read enjoyable chapters. Few books are must-read but Thank You IBM! will quickly be at the top of your list and America’s most read list.

Book Description
Regulatory and industry-specific requirements, such as SOX, Visa PCI, HIPAA, and so on, require that sensitive data must be stored securely and protected against unauthorized access or modifications. Several of the requirements state that data must be encrypted. IBM® i5/OS® offers several options that allow customers to encrypt data in the database tables. However, encryption is not a trivial task. Careful planning is essential for successful implementation of data encryption project. In the worst case, you would not be able to retrieve clear text information from encrypted data. This IBM Redbooks® publication is designed to help planners, implementers, and programmers by providing three key pieces of information: Part 1, "Introduction to data encryption" on page 1, introduces key concepts, terminology, algorithms, and key management. Understanding these is important to follow the rest of the book. If you are already familiar with the general concepts of cryptography and the data encryption aspect of it, you may skip this part. Part 2, "Planning for data encryption" on page 37, provides critical information for planning a data encryption project on i5/OS. Part 3, "Implementation of data encryption" on page 113, provides various implementation scenarios with a step-by-step guide.
