One of the very popular uses of GoldenGate is to replicate data between databases running in different RDBMS. Different RDBMS systems have different data types and use different data structures to store the data. It is due to these complications that replicating between different systems becomes a complex task. GoldenGate extracts data from a database and stores it in its proprietary format. This data in proprietary format can then be replayed in any other supported database. You can use this feature to perform a one-off data migration from one RDBMS to another or you can use it to set up a permanent replication between a data set from one RDBMS to another.
In this recipe we will set up a continuous replication between an Oracle database and an SQL Server database. We will also cover the steps to install and configure GoldenGate in an SQL Server environment.
