Oracle GoldenGate 11g Implementer's guide

By: John P Jeffries, John P Jeffries

Overview of this book

Data replication is an important part of any database system that is growing due to today's demand for real-time reporting and regulatory requirements. GoldenGate has recently become Oracle's strategic real-time data replication solution. Until now, very little has been written about how to implement GoldenGate in a production enterprise environment where performance, scalability, and data integrity are paramount. Your days of dismay over the lack of documentation over Oracle GoldenGate are over. Welcome to Oracle GoldenGate 11g Implementer's guide – a comprehensive practical book, which will deliver answers to your questions in a clear, concise style, allowing you to progress effectively in a timeline-driven environment. Based on the author's own experience, this long awaited GoldenGate administration book has all that is required to install, design, configure, and tune data replication solutions suited to every environment. Be the first to master GoldenGate's power and flexibility by reading this unique hands-on implementation companion. Systems need to send data from one system to another in a timely manner to satisfy the ever-increasing need for speed. Regardless of whether you are a novice or an expert – or someone in between – this book will guide you through all the steps necessary to build a high-performance GoldenGate solution on Oracle11gR1. Expert users can dive into key topic areas such as performance tuning or troubleshooting, while novice users can step through the early installation and configuration chapters, later progressing to the advanced chapters. This book is more than an implementation guide. It offers detailed real-life examples, encouraging additional thought and discussion by going beyond the manual. With Oracle GoldenGate 11g Implementer's guide in hand, you'll be designing, installing, and configuring high-performance solutions using GoldenGate in less time than you can say "replicate"

New releases


At the time of writing this book, a new release of Oracle GoldenGate has become available:

Version 11.1.1.0.0 Build 078 for Oracle 11gR2

This version runs on the Oracle Sun Exadata2 Database Machine (11.2.0.1), but is not without some performance issues. A known bug causes slow write performance to a Database file system (DBFS), which would typically be used to store the GoldenGate persistent files in a RAC environment. During tests, the measured data pump write rate (with no Replicat processes running) into DBFS was 1.5 to 1.7 MB/sec. For comparison, the Data Pump write rate into a regular Linux file system on the same server was in the 30 MB/sec range and simple writes using the Linux dd utility into the same DBFS mount produced rates in the 30 to 50 MB/sec range.

Happily however, Oracle states this issue is fixed in the next release of GoldenGate: Version 11.1.1.0.5 Build 003.

DBFS enhancements

When configuring DBFS, it is highly recommended to adopt the following options:
