Oracle Information Integration, Migration, and Consolidation

Overview of this book

The book covers data migration, data consolidation, and data integration, the three scenarios that are typically part of the information integration life cycle. Organizations typically find themselves migrating data to Oracle and either later, or at the same time, consolidating multiple database instances into a single global instance for a department, or even an entire company. The business savings and technical benefits of data consolidation cannot be overlooked, and this book will help you to use Oracle's technology to achieve these goals. This highly practical and business-applicable book will teach you to be successful with the latest Oracle data and application integration, migration, information life-cycle management, and consolidation products and technologies.In this book, you will gain hands-on advice about data consolidation, integration, and migration using tools and best practices. Along the way you will leverage products like Oracle Data Integrator, Oracle GoldenGate, and SQL Developer, as well as Data Hubs and 11gR2 Database. The book covers everything from the early background of information integration and the impact of SOA, to products like Oracle GoldenGate and Oracle Data Integrator. By the end you'll have a clear idea of where information and application integration is headed and how to plan your own projects.

Preface

Original architecture — nightly batch process


The current system is a typical legacy application that uses time-delayed processing. This means that all the work from the day is collected in a set of files and then processed at a specific time each day. The bulk of the processing is done by mainframe utilities like IEBGENER (Access Method Services), Syncsort, and IDCAMS. IEBGENER is an IBM utility used to write to the flat sequential files. IDCAMS is an IBM utility used to read and write to the Virtual Storage Access Method (VSAM) data store. Syncsort is a file sorting utility from the company of the same name. One COBOL program contains all the business logic and business rules to add new members to the application. Job Control Language (JCL) is used to control the flow of processing, writing to temporary data sets, and calling programs and utilities to format files for processing.
