Oracle GoldenGate vs. Qlik Replicate

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.

Qlik Replicate works very well with relational data platforms, both on premise and in the cloud, for example Oracle, SQL Server, PostgreSQL, MySQL and others, it also works very well with DB2. If the data source is MongoDB, it is more complicated and currently there is no possibility of sending data to MongoDB.

• 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

• Qlik Replicate brought a great experience with respect to the ease of implementation and great UI. We had a software that was a blackbox for the team and was very hard to maintain. Qlik Replicate implementation helped us avoid dependency on one resource.
• Global transformation and in-built functions are what I like in our project.
• You can customize the conversion/transformation using a JSON file generated by Qlik Replicate, and it is very convenient.

• 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.

• The base Replicate web GUI is lacking. If you have dozens or more tasks, it's hard to get a sense of how they're performing. Enterprise Manager solves all of these problems but is a separate install.
• The support portal is extremely difficult to navigate. It's hard to track down exactly what you're looking for.
• It would be helpful to have better documentation and example queries for the tables in the Enterprise Manager analytics database.
• Destination databases that don't support common DDL commands behave unpredictably. And the replication of schema changes isn't consistent.

Oracle GoldenGate is a core part of our business.

The availability of the replicated data in disparate environments has is now crucial. Replacing a product like Qlik Replicate would require significant time, investments, and work. In addition, Qlik Replicate is reasonably reliable with few failures.

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.

We now have greater business flexibility and scalability, and our big data integration projects have a quick rate of growth, which has been profitable for us. Independent of the sources involved, maintaining data consistency between sources is easy. One of my favorite features is the way it lets owners of the source system start and stop processes from updating their system windows.

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.

The issue I've had is that Qlik does an awful job of keeping their customers informed when new versions of the software are available. We found that we were using a version that was no longer supported and could never get help. When it came time to get us upgraded so that we were on a current version, no one knew how to help get us to where we needed to be. We had to purchased professional services time and even then I was basically on my own to get everything built out and set up. Qlik needs to be more proactive with communicating about new releases and how to get your version upgraded in the most secure, safe way possible.

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.

Follow the directions from the Qlik documentation. They are pretty straight forward and easy enough to follow. If you follow these, then you are not likely to have issues on implementation.

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.

Great tool for data replication solution for Oracle/SQLServers/etc. Real easy to get it set up and start realizing business value. Getting the PoC accomplished in a short window. Product costing and easy to start small and scale as needed. It helped cover most of our ask compared to other solutions.

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.

• 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".

• Prior to using Qlik Replicate, we used an ETL solution to copy data from the Oracle ERP system to the Microsoft SQL Server BI system at a 15-minute interval. It was very tedious to maintain. Qlik Replicate is much easier to use and we replicate data near real-time now.
