QA76.8.I1013 H67 2002 004.1’25—dc21 2002010929 Acknowledgments I would like to thank the many members of the IBM development and marketing support teams who under significant IBM work pressures took time to answer my questions and help review my work. There were those that committed considerable efforts to support this effort: Networking/Communications James Goethals, zSeries Networking Offering Manager Linux and z800 Linux Pricing Nancy Scala, zSeries Product Marketing Manager I/O and Storage and z/OS.e and zELC Pricing Gita G. Berg, zSeries Marketing VSE Jerry Johnston, VSE Senior Consultant VM and z/VM Denny Refsnider, VM Marketing/Announcements Pamela Christina, z/VM Marketing, Tech. Conferences, Events Management Web Editor Reed Mullen, VM Product Management Carol Kudritz, VM Software Vendor Relationship Management Alan Altmark, z/VM Strategy, Design & Development VM, z/VM & VSE Nancy Eade, zSeries Product Marketing Manager I would like to pass on my special thanks to Jim Goethals who was so gracious and helpful in getting the networking and communications material and message correct; to Gita for not only helping me with gen- eral material and the storage and printer product questions but for her patience in helping me construct the pricing example for z/OS.e and zELC; to Nancy Scala’s help in construction of the example for z800 with Linux; and to Nancy Eade who coordinated the VSE, VM and z/VM responses as well as her support across the full spectrum of the book. Without the help of all of these fine people and competent IBM’ers this book would not have seen the light of day. I would also like to acknowledge the willingness of IBM to permit me to use their graphics and tables that are reproduced in this book which are from their IBM eServer zSeries 900 Technical Guide (SG24-5975-00) and IBM eServer zSeries 900 and z/OS Reference Guide (G326-3092-00) plus several Customer Marketing presentations. Most important, I would like to thank my wife, Pat, for her support and willingness to pick up some of my household tasks while I spent days and evenings on this endeavor.

Foreword vii Foreword zSeries: Architected for e-Business, But True to Its Roots While the mainframe has a proud forty-year history and has helped transform virtually every aspect of modern life, the IBM eServer zSeries, by comparison, is a precocious two year old. Totally redesigned from the ground up in October 2000 for the launch of eServer, the zSeries is the foundation on which many of today’s eServer innovations are based. At the same time, it is called zSeries, for near zero downtime, because of the outstanding mainframe attributes it carries forward to users. The careful blending of new capabilities and time-proven qualities of ser- vice has made the zSeries an important player in the e-business transfor- mation taking place in today’s society. It also is the hallmark of a system that has been reinvented several times to meet the emerging demands of the IT marketplace. The IBM press release that announced the new IBM eServer zSeries described how it differed from its predecessors. It called the z900 the first mainframe built from scratch with e-business as its primary func- tion—with the ability to run up to hundreds of virtual servers within one physical box and the capability to replace racks full of competitive servers. It also outlined its new 64-bit operating system, z/OS, as well as new software pricing, designed to let customers pay based on what they use instead of total system capacity. The new zSeries set high stan- dards, but what has transpired during the past two years has surprised even the most enthusiastic mainframe supporters. In addition to driving renewed growth and interest in the main- frame with the z900, IBM has introduced new offerings to provide the benefits of zSeries to a broader spectrum of customers. Following are a few examples. vii viii Exploring IBM ~ zSeries and S/390 Servers • January 2002: IBM announces plans to deliver a Linux-only mainframe. The new server is capable of consolidating from 20 to hundreds of UNIX and Intel servers, bringing the superior total cost of ownership, performance and security of the IBM mainframe to an entirely new class of customers.

There are 405,535 employees and 798,152 stockholders at year-end. Organization IBM President John F. Akers succeeds John R. Opel as chief executive officer, effective February 1. Mr. Akers also is to head the Corporate Management Board and serve as chairman of its Policy Committee and Business Operations Committee. PC dealer sales, support and operations are transferred from the Entry Systems Division (ESD) to the National Distribution Division, while the marketing function for IBM’s Personal Computer continues to be an ESD responsibility. IBM announces in September a reorganization of its U.S. marketing operations. Under the realignment, to take effect on Jan. 1, 1986, the National Accounts Division, which markets IBM products to the company’s largest customers, and the National Marketing Division, which serves primarily medium-sized and small customer accounts, are reorganized into two geographic marketing divisions: The North-Central Marketing Division and the South-West Marketing Division. The National Distribution Division, which directs IBM’s marketing efforts through Product Centers, value-added remarketers, and authorized dealers, is to merge its distribution channels, personal computer dealer operations and systems supplies field sales forces into a single sales organization. The National Service Division is to realign its field service operations to be symmetrical with the new marketing organizations.

  • Enabling White-Box Reuse in a Pure Composition Language
    Enabling White-Box Reuse in a Pure Composition Language Diplomarbeit der Philosophisch-naturwissenschaftlichen Fakultat¨ der Universitat¨ Bern vorgelegt von Andreas Schlapbach Dezember 2002 Leiter der Arbeit: Prof. Dr. O. Nierstrasz Nathanael Scharli¨ Institut fur¨ Informatik und angewandte Mathematik i Abstract Inheritance is a key concept of object-oriented programming languages, features such as conceptual modeling and reusability are largely accredited to it. While many useful com- ponents have been, and will be, developed in this paradigm, the form of white-box reuse offered by inheritance has a fundamental flaw: reusing components by inheritance requires an understanding of the internals of the components. We can not treat components of object-oriented languages as black-box entities, inheritance breaks encapsulation and in- troduces subtle dependencies between base and extending classes. Component-oriented programming addresses this problem by shifting away from program- ming towards software composition. We build applications by scripting components. In- stead of overriding the internals of a component, we focus on composing its interfaces only. This form of black-box reuse leads to a flexible and extendible architecture with reusable components. In this master's thesis we propose a migration strategy from class inheritance { a white- box form of reuse { to component composition as a black-box form of reuse. We present a language extension that gives us the power of inheritance combined with the ease of scripting. It enables us to reuse Java components using inheritance in JPiccola { a small, pure and general composition language implemented on the Java platform { at a high level of abstraction. Using the services provided by the language extension we can seamlessly generate interfaces and subclasses from JPiccola.

    The International Newsletter for Smalltalk Programmers May 1993 Volume 2 Number 7 ecognizing Smalltalk’s increasing importance as a mainstream pro- TOWARD A gramming language and acting as a large user of the language, IBM D recently proposed the formation of a standards effort within ANSI to define a Smalltalk language standard and offered a “common SMALLTALK base” strawman to start such an effort. At this time the proposal has beenQaccepted by the ANSI SPARC committee, and the formation of an ANSI STANDARD: Smalltalk committee has begun. This article focuses on technical issues regarding the common base. We have written a companion article that will appear in OBJECT MAGAZINE,which outlines TECHNICAL ASPECTS the history of the development of the common base. WHAT IS THE COMMON BASE? OF THE COMMON BASE As part of the proposal for an ANSI Smalltalk standards effort, we have con- tributed a “strawman” as the starting point for standardization. That strawman is contained in the IBM document entitled Smalhalk Portability A Common Base By R.J. DeNatale and comprises chapters 3–5 and appendices A and B from that document. * & Y.P. Shari This proposal is not our work entirely. It is the result of an 18-month-long col- laboration among five companies: IBM, Digitalk, KSC, OTI, and ParcPlace.

When studying the specification for a language one expects to 1 The Smalltalk standard: Technical learn things, such as how to do arithmetic, how to code conditional logic, and so aepects of the common base forth.
