In order to improve the performance and operational efficiency of businesses worldwide, a customer using SAP® wanted to establish a global business program to define and implement a standardized, group-wide business process architecture and associated master data for the parameterization of the group of software tools. The expected growth of the number of users and the size of the database would be at a level never reached by other customers, however, so IBM® was asked to undertake the following tasks: * Test the application to be sure that it can sustain such growth. This project illustrates the new near real time business intelligence (BI) context approached by customers who want the ability to rapidly analyze their business data to gain market shares. Data today comes from many diverse global sources and needs to be merged into an intelligent data warehouse. This IBM Redbooks® publication describes the testing that was done in terms of performance and manageability in an SAP NetWeaver® BI and DB2® environment on IBM System p™ when scaling a client's solution to a data warehouse of 60 terabytes (TB). This book resulted from a joint cooperative effort that included the PSSC, the IBM/SAP International Competency Center, the DB2-SAP Center of Excellence, SAP AG, and a customer. The customer involved in this project is a worldwide company employing more than 250,000 employees with factories and logistics operations in almost every country in the world. This project involved multiple technical skills and multiple products, as described here: * Chapter 1, "Project overview: business objectives, architecture, infrastructure, and results" on page 1, summarizes the entire project, starting from the business needs through the description of the environment and options used, to the results achieved. This chapter can be viewed as an executive summary from an IT specialist perspective. * Chapter 2, "The SAP NetWeaver BI perspective" on page 47; Chapter 3, "The DB2 perspective" on page 127; and Chapter 4, "The IBM System p perspective" on page 287, provide detailed views of the project from the perspectives of SAP specialists, DB2 specialists, and System p and AIX® specialists, respectively. * Chapter 5, "The system storage perspective" on page 319, and Chapter 6, "The Tivoli Storage Manager perspective" on page 349, describe the storage environment and the manageability issues in such a large environment. * Finally Appendix A, "The scripts used" on page 395, provides the scripts that we needed to develop for this project.

This IBM® Redbooks® publication focuses on migration of a data center from a Tivoli® Framework environment and a Tivoli Configuration Manager-based management model to the new Service-Oriented Architecture (SOA), provided by Tivoli Provisioning Manager for Software V 5.1. In addition to migration, we also discuss the coexistence environment, where Tivoli Provisioning Manager for Software drives the Tivoli Management Framework environment. Because Tivoli Provisioning Manager for Software shares its roots with Tivoli Provisioning Manager 5.1, all of the migration scenarios we describe in this book apply to Tivoli Provisioning Manager 5.1, as well. To give you ideas for various migration possibilities, we describe several customer environments and then describe the suggested approach for moving to a Tivoli Provisioning Manager environment. We also tell you how the two environments can coexist during the migration process. We provide a feature-by-feature comparison between common Frameworks, Tivoli Configuration Manager operations, and their equivalent in Tivoli Provisioning Manager. This book is a reference for IT Specialists who implement data center migration from a Tivoli Management Framework and Tivoli Configuration Manager-based management model to Tivoli Provisioning Manager for Software V 5.1 or Tivoli Provisioning Manager V 5.1.

In this IBM® Redbooks® publication, we introduce the concept of cross-site mirroring (XSM) as implemented in IBM OS/400® or i5/OS® at V5R3M0 and later. XSM describes the replication of data at multiple sites. It involves the use of clustering, cluster resource groups (CRGs), independent auxiliary storage pools (IASPs), and other components. In this updated version, we include the new i5/OS V5R4 functions of Administrative Domain and Source Site Tracking. We also include preview information of the Target Site Tracking function. An additional component of this highly available technology is that XSM keeps two identical copies of an independent disk pool at two sites to provide high availability and disaster recovery. These sites can be geographically close to one another or far apart, depending on the needs of the business. This book is written for IBM technical professionals, Business Partners, and customers who are considering, planning, and implementing a highly available solution on the IBM System i5™ platform.

Data migration has become a mandatory and regular activity for most data centers. Companies today need to migrate data not only when a technology replacement is due, but also for other purposes such as consolidation, load balancing, and disaster recovery.

Service-oriented architecture (SOA) is one of the most important topics on the agenda of any IT person. SOA involves a new vision of how to design, develop, and manage applications. It also has new requirements when building an architecture for the underlying infrastructure. This IBM Redbooks publication is the result of a project managed in the IBM European Design Center, based in Montpellier, France. The scope of the project involved helping a major worldwide customer in the automotive industry to validate and justify an SOA implementation. In particular, the customer wanted to add new business values to work with its partners, by adding new data models. It also wanted to modernize an infrastructure, by adding new Internet interfaces. The customer faced the need to eradicate an obsolete programming language. Furthermore, it wanted to build a smooth migration path, with as few risks and costs as possible. The thought, planning, and architecture of the new system, which included integration of the SOA concepts, was built by the customer with the participation of Atos Origin, a leading international IT services provider. The existing customer IT infrastructure was already built around UNIX systems, IBM System z, non-IBM clusters, SAP solutions, 3270 screens, IMS-DL/I databases, and specific code. SOA was the right solution to connect this existing environment to new components using Java, Web services, and DB2 in particular. This book explores the business needs and the architectural choices that were faced by the customer. It describes the mock-ups and prototypes, provides performance numbers that were used to validate the decisions, and explains how they were implemented. It also suggests a generic and riskless solution to eradicate the obsolete programming language.

In a corporate environment, documents are usually created or captured in a decentralized environment with no overall surveillance. Many corporations have no formal process of retaining these documents as records, which can increase storage costs. In addition, when litigation requests occur, companies can spend a huge amount of money and resources to locate records. In the case when a company is not able to locate records or to locate them on a timely manner, the company is subjected to a financial penalty or, more importantly, damage to the company's reputation. IBM Records Manager is an application and an engine that provides records management capabilities to existing business applications. It provides a single and consistent records management platform to help companies meet government and industry requirements for formal records management. This IBM Redbooks publication provides an introduction to records management and IBM Records Manager. Solution architects, designers, and implementers who plan to implement IBM Records Manager will find this book useful. It also serves as a guide for system administrators or records administrators in performing common records management administration tasks in IBM Records Manager. Lastly, the first part of this book serves as a good starting point for anyone who is interested in exploring the world of records management.

This IBM Redbooks publication is intended for use by those generally familiar with most of the iSeries IBM-provided performance tools available through the i5/OS operating system’s commands and the additional cost Performance Tools for iSeries, 5722-PT1, licensed program. i5/OS comes with a detailed program level performance data collection capability called the Performance Explorer (PEX). i5/OS commands supporting the collection include Add PEX Definition, Start Performance Explorer, and End Performance Explorer. One of the Performance Explorer (PEX) collection options is called Statistics (STATS), which collects the program level performance statistics, including CPU usage, disk I/O activity, and the occurrence of certain i5/OS and System i microcode level events. The Print PEX Report function of 5722-PT1 provides a basic view of this STATS data. PEX Statistics provides a richer interface for collection and analysis of the *STATS performance data than is available through the i5/OS PEX command and the Print PEX Report output.
