Overview of this book

Oracle Goldengate 11g Complete Cookbook is your complete guide to all aspects of Goldengate administration. The recipes in this book will teach you how to setup Goldengate configurations for simple and complex environments requiring various filtering and transformations. It also covers various aspects of tuning and troubleshooting the replication setups using exception handling, custom fields, and logdump utility.The book begins by explaining some basic tasks like Installation and Process groups setup. You will then be introduced to some further topics including DDL replication and various options to perform Initial Loads. You will then learn some advanced administration tasks such as Multi Master replication setup and conflict resolution. Further recipes, contain the cross platform replication and high availability options for Goldengate.

Installing and using Oracle GoldenGate Director Client to manage the GoldenGate instances

In this recipe, you will learn how to install the Oracle GoldenGate Director Client and then add the Oracle GoldenGate instances to the configuration. You will also learn how to manage the Oracle GoldenGate instances through the Oracle GoldenGate Director Client.

Getting ready

For this recipe, we will refer to the GoldenGate setup done in the Setting up a simple GoldenGate replication configuration between two single node databases recipe in Chapter 2, Setting up GoldenGate Replication. Both the source and target GoldenGate instances of this setup will be configured in the GoldenGate Director setup. For the GoldenGate Director server setup, we will refer to the set up performed in Installing Oracle GoldenGate Director Server in this chapter. The GoldenGate Director server must be up and running. You would also need to download the Oracle GoldenGate Director Client binaries from the Oracle edelivery/otn...
