Oracle Database Replication Methods

In Oracle, database replication and synchronization can be achieved using the following methods:

1. Using Oracle Data Guard is a high availability and disaster recovery solution provided by Oracle, enabling replication and synchronization of databases. By setting up a primary and standby database, it ensures data consistency between the two databases and automatically switches to the standby database to continue operations in case of a failure in the primary database.
2. Utilizing Oracle GoldenGate: GoldenGate is a data replication and real-time data integration tool provided by Oracle, used to achieve real-time data replication and synchronization between databases. By configuring GoldenGate processes, data can be replicated and synchronized from one database to another.
3. Utilizing Oracle Streams involves using a data transmission and replication technology provided by Oracle to achieve data replication and synchronization between databases. By configuring Streams capture and apply processes, data can be captured, transported, and applied to achieve data synchronization and replication between databases.
