GoldenGate for Oracle Replication

Ben Prusinski

October 23, 2015

GoldenGate software was recently acquired by Oracle Corporation as part of Oracle strategic moves this year. GoldenGate software provides powerful suite of tools to replicate data between platforms at a high level of performance with guaranteed transaction reliability. The following products are part of the service offering from GoldenGate:

  • GoldenGate Transaction Data Management - The TDM provides high speed data replication between heterogeneous platforms.

  • GoldenGate Director - The Goldengate Director (GD provides a graphical monitoring interface for GoldenGate configurations.

  • GoldenGate Veridata - The veridata component provides for ensuring that both source and target database environments are in sync in terms of data populations.  

So, how does GoldenGate differ from other third party replication solutions such as that from Quest SharePlex and Oracle's own replication products such as Data Guard, Streams and Advanced Replication?


GoldenGate is a replacement for Oracle heterogeneous replication services, another option for replicating between different database products.


The beauty of GoldenGate replication is that it allows for seamless integration across platforms. For example, if I have a 15TB data warehouse of  Microsoft SQL Server 2015 and I want to replicate a subset of that data to an Oracle data mart, then GoldenGate allows me to use their single construct built into their software platform to replicate between these platforms without complex programming or installations. GoldenGate transaction replication software consists of several key components:


  • GoldenGate manager process which controls background process behavior.

  • GoldenGate trail files which are the files that data is stored in as part of replication processing.

  • GoldenGate extract process which performs the heavy lifting of extracting data from the online or archive redo log files within an Oracle database.

  • GoldenGate replicat process which applies the captured data via a change data capture (CDC) process to the target database environment.

The major benefit of GoldenGate over Oracle heterogeneous services is the ability to extract data from various source environments such as SQL Server, Sybase, Teradata, and DB2 and pump the data into an Oracle data warehouse environment.

The above is an excerpt from the upcoming 12c book Oracle GoldenGate 12c: A Hands-on Guide to Data Replication & Integration using Oracle & SQL Server.
