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.

Replicating data from an active standby database in Archivelog mode only

In this recipe you will learn how to set up a GoldenGate configuration to replicate the data from the archived logs on an active standby database.

Getting ready

The setup used for this recipe consists of a primary database called DBORATES running on prim1-ol6-112. A physical standby database for DBORATES has been created with Oracle Active Dataguard on stdprim1-ol6-112. The standby database is configured to write its archived logs to /u01/app/oracle/fast_recovery_area/STDDB. The target database called TGORTEST is running on stdby1-ol6-112. GoldenGate binaries are already installed on stdprim1-ol6-112 and stdby1-ol6-112 and a Manager process has been set up on both of these servers. A GoldenGate Administrator has already been created in both the DBORATES and TGORTEST databases. A TNS entry DBORATEST has been set up on stdprim1-ol6-112 which resolves to the DBORATES database running on prim1-ol6-112.
