Oracle Golden Gate Replication Architecture

Trails or extract files.

Oracle golden gate replication architecture.

The captured data is written to a file called the source trail. Oracle goldengate is installed separately to the source and target servers and the configurations of the servers can be different. Oracle goldengate s modular architecture for database to database replication enables high speed reliability and flexibility. The hub must be located close in network proximity to the target database leading to two possible architectures.

The trail is then read by a data pump sent across. This is the basic configuration. I have done 2000 table replication with goldengate or sql server replication tool for dwh databases in many clients. In this post we ll understand the golden gate replication flow and examines each of the architectural components.

It enables high availability solutions real time data integration transactional change data capture data replication transformations and verification between operational and analytical enterprise systems. Oracle ms sql postgre sql mysql and ibm db2. Goldengate tutorial oracle goldengate concepts and architecture made simple. Using this technology it enables cost effective and low impact real time data integration and continuous availability solutions.

Oracle goldengate is composed of the following components. Oracle goldengate supports the replication of data across various heterogeneous platforms. Oracle goldengate is a comprehensive software package for real time data integration and replication. Figure 1 2 illustrates the logical architecture of oracle goldengate for initial data loads and for the synchronization of dml and ddl operations.

Oracle goldengate moves committed transactions with transaction integrity and minimal overhead on the infrastructure. The oracle goldengate hub is an architectural concept that places the oracle goldengate software on a different host than the databases being operated against. Goldengate replication flow the typical goldengate flow shows new and changed database data being captured from the source database. Thanks to its oracle goldengate hybrid structure it can support replication in cross platform or database.
