As companies implement data integration across their enterprise, it can often lead to a data tragedy, whether that is complexity, high cost, outdated information, or even lost data. Let’s take a look at some common data tragedies and how data replication can help you avoid them.

Load testing of database replication finds the upper limit of how well the system can perform, and it provides assurance that replication will make it through times of peak usage. Let's look at how to simulate production activity for SymmetricDS data replication in a lower environment so you can deploy with confidence.

Common batch mode was enhanced in SymmetricDS 3.11 to allow any group of nodes to share batches. Let's look at what common batches are and why this is a big deal for database replication with more than a couple nodes.

The initial data load is an important first step for data replication, so in the latest version 3.10 of SymmetricDS Pro, we worked hard to improve the Outgoing Loads screen to make it easy to follow progress and see how long the load will take. Here are some highlights that benefit long-running loads.

For a large database, the conventional initial load that extracts each table, one by one, can run for days. Not everyone can wait for that, so here are some tips to improve initial load performance on SymmetricDS.

Since the beginning of the SymmetricDS project, change data capture has been supported on Oracle and Oracle RAC. That's because Oracle is a popular database management system, ranking #1 on the DB-Engines Ranking for years. Recently, I helped deploy SymmetricDS in a unique application environment based on Oracle RAC, where it was challenged to keep up with bulk, concurrent changes. By adjusting some new parameters specifically designed for RAC, we were able to meet performance requirements.

There are some common mistakes when implementing a data replication solution that should be avoided. As I've helped companies use SymmetricDS effectively for database replication as part of their data integration strategy, I've seen the same mistakes and misunderstandings. In this article, I'll explain some of these pitfalls and give you some tips on what to do instead.
