AWS Database Migration Service vs. Oracle GoldenGate

As stated previously, AWS Database Migration Service excels when replicating very specific data elements between environments. AWS Database Migration Service handles replication tasks to load equipment assets or customer job sites from production to QA databases very well. Full load replication - e.g., we need an exact copy of the production database in another region - works well. But when we need to load the QA database with the latest production data - it does work as well. AWS Database Migration Service comes up short because we do not want to wipe the QA database completely and make an exact copy. We want to keep what's already in the QA database and add production data so that we can QA with that level of volume. And at least with our database design, we end up having to do a lot of manual data manipulation and de-duplication.

Oracle [GoldenGate] is well suited for data replication where real-time results are important, such as data reporting. There is potential to have the users query the replicated database, which can have separate resources set up to be compressed or using lower performing or cheaper resources. As mentioned, columns with LOBs can become a headache, as they will need to be synchronized in their own group many times. Tables containing data in CHAR, VARCHAR, NUMBER, DATE, or other non-LOB columns, however, are able to be replicated quite seamlessly. [Oracle GoldenGate] does provide a way to review errors that are encountered, so that is a positive if their is scrutiny around data integrity.

• OGG can be used and integrated with heterogeneous databases as well as homogeneous databases.
• OGG is easy setup as well as easy learning curve
• OGG supports large databases
• OGG support many uses cases (topologies) such as unidirectional replication, bidirectional, peer-to-peer, Broadcast, Cascading replication etc.
• OGG can be used not only for CDC (change capture), can be used to full load

• The earlier versions of Golden Gate were complex to use as there was no front end. All that works was the command line.
• The cost of the product can be a detriment to most companies.
• The product has been augmented over the years and has so many features that it can be overwhelming.

Once set up, it's very easy to use and keep running, it's getting to that point that can make it cumbersome to some. Also, depending on the data that you want to replicate, the configuration files can become quite cumbersome to maintain. Learning curve can be high for some who are not as experienced with databases and transactions.

Oracle GoldenGate has only gone down for us when the data being sent was bad.

Oracle GoldenGate's performance is great for our use cases. Your mileage may vary.

Oracle Support for Oracle GoldenGate has been quite responsive and quite helpful in the few situations where we've needed it. Furthermore, the documentation on Oracle GoldenGate is so good that we often do not need to contact support with issues as the fix is already documented and able to be run by us without needing to open a ticket.

We've had Oracle consultants come as well for training days to talk about new features, parts of Oracle GoldenGate we may not be using and things of that nature. The consultants they send are great as they're very knowledgeable about all things Oracle GoldenGate and great resources for any questions or concerns you may have with the product.

We used Oracle University for our Oracle Golden Gate Training and it was top notch. We were able to turn our whole DBA team to Oracle GoldenGate newbies to Oracle GoldenGate troubleshooting experts in a matter of a few days, while this obviously did not come cheap, the company felt that it was worth the investment.

If Oracle GoldenGate is new to your organization, expose as many DBAs as possible to it. Having your whole team fluent in it will overcome early operational hurdles and allow it to more quickly become an accepted and supported part of your supported platform for your team that will enable the business to use it to its fullest.

Oracle is tightly integrated with Oracle Exadata and is a better fit for using Oracle databases.Both products support heterogeneous databases but using Exadata, it just seemed to make better sense to use the Oracle GoldenGate product. We also take advantage of the Oracle GoldenGate Veridata product to compare datasets and make sure they are still in sync.

Have never had any issues with scaling Oracle GoldenGate itself, however Oracle GoldenGate Monitor does have scaling issues, but with Oracle GoldenGate now able to be monitored by Oracle Enterprise Manager, this is no longer an issue, in my opinion.

• Set it and forget it for maintaining data consistency - moderate cost, zero to minimal maintenance
• High touch production data loads into QA - negative ROI engineering time investment far exceeded our predictions

• Oracle GoldenGate guarantees our standing-by database in passive data center, is always in "pre-warmed" status, as the data is always in-sync with the master database in our active data center. At any time, the standing-by database can kick in in case the active DC encounters the serious issue. This significantly increases the IT application's high availability and promise to "business as usual".
