Optimizing DB2 Queries with IBM DB2 Analytics Accelerator for z/OS

By: Paolo Bruni,Patric Becker,Willie Favero,Ravikumar Kalyanasundaram,Andrew Keenan,Steffen Knoll,Nin Lei,Cristian Molaro,P S Prem,IBM Redbooks

The IBM® DB2® Analytics Accelerator Version 2.1 for IBM z/OS® (also called DB2 Analytics Accelerator or Query Accelerator in this book and in DB2 for z/OS documentation) is a marriage of the IBM System z® Quality of Service and Netezza® technology to accelerate complex queries in a DB2 for z/OS highly secure and available environment. Superior performance and scalability with rapid appliance deployment provide an ideal solution for complex analysis. This IBM Redbooks® publication provides technical decision-makers with a broad understanding of the IBM DB2 Analytics Accelerator architecture and its exploitation by documenting the steps for the installation of this solution in an existing DB2 10 for z/OS environment. In this book we define a business analytics scenario, evaluate the potential benefits of the DB2 Analytics Accelerator appliance, describe the installation and integration steps with the DB2 environment, evaluate performance, and show the advantages to existing business intelligence processes.

Co-locating Transactional and Data Warehouse Workloads on System z

As business cycles speed up, many customers gain significant competitive advantage from quicker and more accurate business decision-making by using real data. For many customers, choosing the path to co-locate their transactional and analytical workloads on System z® better leverages their existing investment in hardware, software, and skills. We created a project to address a number of best practice questions on how to manage these newer, analytical type workloads, especially when co-located with traditional transactional workloads. The goal of this IBM® Redbooks® publication is to provide technical guidance and performance trade-offs associated with resource management and potentially DB2® data-sharing in a variety of mixed transactional / data warehouse System z topologies. The term co-location used here and in the rest of the book is specifically defined as the practice of housing both transactional (OLTP) and data warehouse (analytical) workloads within the same System z configuration. We also assumed that key portions of the transactional and data warehouse databases would reside on DB2 for z/OS®. The databases may or may not reside in a DB2 data-sharing environment; we discuss those pros and cons in this book. The intended audience includes DB2 data warehouse architects and practitioners who are facing choices in resource management and system topologies in the data warehouse arena. This specifically includes Business Intelligence (BI) administrators, DB2 database administrators (DBAs) and z/OS performance administrators / systems programmers. In addition, decision makers and architects can utilize this book to assist in making platform and database topology decisions. The book is divided into four parts. Part I, "Introducing the co-location project" covers the System z value proposition and why one should consider System z as the central platform for their data warehousing / business analytics needs. Some topics are risk avoidance via data consolidation, continuous availability, simplified disaster recovery, IBM Smart Analytics Optimizer, reduced network bandwidth requirements, and the unique virtualization and resource management capabilities of System z LPAR, z/VM® and WLM. Part I also provides some of the common System z co-location topologies along with an explanation of the general pros and cons of each. This would be useful input for an architect to understand where a customer is today and where they might consider moving to. Part II, "Project environment" covers the environment, products, workloads, workload drivers, and data models implemented for this study. The environment consisted of a logically partitioned z10TM 32way, running z/VM, Linux®, and z/OS operating system instances. On those instances we ran products such as z/OS DB2 V9, IBM Cognos® Business Intelligence Version 8.4 for Linux on System z, InfoSphereTM Warehouse for System z, InfoSphere Change Data Capture, z/OS WebSphere® V7, Tivoli® Omegamon for DB2 Performance expert. Utilizing these products we created transactional (OLTP), data warehouse query, and data warehouse refresh workloads. All the workloads were based on an existing web-based transactional Bookstore workload, that's currently utilized for internal testing within the System p® and z labs. While some IBM Cognos BI and ISWz product usage and experiences information is covered in this book, we do not go into the depth typically found in IBM Redbooks publications, since there's another book focused specifically on that

Cantonese: Since the 19th Century

By: Hung-nin Samuel Cheung

ONE OF THE MOST SPOKEN DIALECTS in China, Southeast Asia, and globally, Cantonese was nevertheless deemed a local dialect enjoying little prestige among the intellectuals. Not much was recorded in official documents or gazetteers about the early history of Hong Kong. The Cantonese language and its origin remained much of a mystery until the mid-20th century when scholars started to accord it with increasing attention. Thanks to dedicated efforts of early missionaries, pedagogues, and linguists, we can now trace back the evolution of modern Cantonese since the 19th century— how differences in sounds, words, and grammar distinguish the old from contemporary speech today. In this book, Hung-nin Samuel Cheung, an acclaimed scholar on the study of Cantonese, offers profound insights to various firsthand century-old materials including language manuals, Bible translations, and maps of Hong Kong, with findings that will be useful for ongoing efforts to study the development of the Cantonese language that has gone through many rounds of incredible and, at times, dramatic changes during the last two hundred years.

The Early Diary of Anaïs Nin, 1914–1920

By: Anaïs Nin

This “amazingly precocious” diary of girlhood in the early twentieth century is filled with a “special charm” (The Christian Science Monitor). Born in Paris, Anaïs Nin started her celebrated diary at age eleven, when she was immigrating to New York with her mother and two young brothers. The diary became her confidant, her beloved friend, in which she recorded her most intimate thoughts and kept watch on the state of her character. Offering an amusing view of Nin’s early life, from age eleven to seventeen, it is also a self-portrait of an innocent girl who is transformed, through her own insights, into an enlightened young woman. “An enchanting portrait of a girl’s constant search for herself . . . will delight her admirers as well as new readers.” —Library Journal “One of the most extraordinary documents in the annals of literature.” —Providence Sunday Journal “[The Early Diary is] not merely an overture to the great performance. It deserves our attention on its own as a revelation of the rites of passage of a young girl in the early part of the [twentieth] century and as an expression of the collision of cultures between Europe and America.” —Los Angeles Times Preface by Joaquin Nin-Culmell
