Oracle Golden Gate Replication Architecture

The hub must be located close in network proximity to the target database leading to two possible architectures.

Oracle golden gate replication architecture.

Oracle goldengate provides real time log based change data capture and delivery between heterogeneous systems. Oracle ms sql postgre sql mysql and ibm db2. Goldengate tutorial oracle goldengate concepts and architecture made simple. Figure 1 2 illustrates the logical architecture of oracle goldengate for initial data loads and for the synchronization of dml and ddl operations.

This is the basic configuration. Thanks to its oracle goldengate hybrid structure it can support replication in cross platform or database. Oracle goldengate supports the replication of data across various heterogeneous platforms. Oracle goldengate is composed of the following components.

The captured data is written to a file called the source trail. I have done 2000 table replication with goldengate or sql server replication tool for dwh databases in many clients. Oracle goldengate features direct access to oracle database heterogeneous replication real time streaming and analysis microservices architecture for goldengate integrate with big data portfolio of integration solutions integrate with oracle veridata oracle management pack for oracle goldengate. It enables high availability solutions real time data integration transactional change data capture data replication transformations and verification between operational and analytical enterprise systems.

Goldengate replication flow the typical goldengate flow shows new and changed database data being captured from the source database. The oracle goldengate architecture consists of four distinct modules and components. Oracle goldengate s modular architecture for database to database replication enables high speed reliability and flexibility. Oracle goldengate moves committed transactions with transaction integrity and minimal overhead on the infrastructure.

Oracle goldengate is installed separately to the source and target servers and the configurations of the servers can be different. Oracle goldengate capture oracle goldengate trail files oracle goldengate delivery oracle goldengate manager figure 3. The oracle goldengate hub is an architectural concept that places the oracle goldengate software on a different host than the databases being operated against. In this post we ll understand the golden gate replication flow and examines each of the architectural components.

Trails or extract files. The trail is then read by a data pump sent across.
