Stop Guessing if Your Data is Correct

    SymmetricDS promises to sync your data, but how do you know it really worked?  How do you really know 2 databases are in sync?  Or, maybe you have well-meaning users that come along after the sync, changing data unexpectedly, and throwing production out of whack.

    Whatever the case, wouldn’t it be nice to be able to compare any 2 databases, and know exactly what the differences are and be able to prove they are in sync?  That’s where a new, experimental feature of SymmetricDS comes in.  It’s called simply dbcompare.  Dbcompare is slated for SymmetricDS 3.8, but if you watch closely, it’s fully included starting in SymmetricDS 3.7.30.

NRF 2016 Recap

JumpMind had another successful trip to NRF in New York City last week. It was very nice to see some of our current SymmetricDS clients face to face and catch up with how the product is working as their data synchronization solution. We also had the opportunity to enjoy some of the fine dining in the city with a couple of our partners. It is always enjoyable to get the chance to sit down and discuss how we can work together and satisfy the data synchronization and integration needs of our clients.

2015 Year In Review

While revving up for a busy and exciting 2016, we thought it would be a good time to look back at JumpMind’s accomplishments in 2015.

It has been a busy year! Our first priority is always supporting our existing customers. In 2015 we continued to provide the high level of support our customers deserve. We've been on the other end of bad support calls, and we never want our customers to experience that with us. The product development team continues to be actively engaged in supporting SymmetricDS so when you ask a question, you get an answer you know you can trust.

Stir Trek 2015

This was JumpMind's first time attending the Stir Trek conference held in Columbus, OH. The conference had a reputation of selling out quickly and established itself as a well known developer conference right here in the midwest. The one day event is also unique compared to other conferences that makes it much more available to developers with such busy schedules. The Avengers theme also contributed to several costumes surfacing in the crowd, including a full replica, Captain America. The precursor to the conference consisted of a game night followed up with a finale event of the new movie, Avengers: Age of Ultron to all that attended.

Keeping Firebird Generators up to Date in your DR Database

 

SymmetricDS can be used to replicate Firebird databases to the cloud for Disaster Recovery. Setup is fairly straightforward. Select the tables you want to sync and the direction you want to sync them and, voilà, you have a backup database. While this is all well and good, if the database relies on id generators for primary key generation, then when failing over to the slave database you will probably end up with generators that no longer reflect the next value to insert.

Permissions

All SymmetricDS synchronization configurations require database connectivity. As a result questions often arise around the topic of database permissions. Specifically what permissions are required for the SymmetricDS user and do the SymmetricDS tables need to run in the same catalog or schema as the tables to be synchronized.

"Hands Off" Recovery

Anyone who has been on a night time support rotation can relate to the 3 AM phone call that gets you groggily out of bed, has you fixing some simple, but important problem, and then leaves you staring at the ceiling by 4 AM wondering if you should just go into work, because you know you aren't getting back to sleep. All of the engineers in our office have been there, done that, and didn't like it very much. That's one of the reasons we focus so much on resilient operations for SymmetricDS including our "Hands Off" Recovery of data synchronization. "Hands Off" recovery is pretty much exactly what it sounds like. SymmetricDS has been built from the ground up to recover and keep databases in sync without manual intervention any time it possibly can.

Bridging Databases with Different Dependencies

Bridge data between databases with data synchronization by using channels to re-order data when the dependencies in each database are different. Each application can model its data differently, so a parent row in one database might map to a child row in another one. Instead of using data transformation to lookup and add dependent data, the order of captured data can be changed to match the constraints of the target database.

Configuring for Reverse Initial Loads

From time to time we are approached with the question of how to do initial loads of data in two directions with SymmetricDS, not just one direction. This feature is available in SymmetricDS and isn't hard to configure. An understanding of how initial loads work in general, combined with a few settings, is all that is needed. This article will walk you through a tutorial on initial loads in general and will then discuss the configuration needed to do a 'reverse' initial load.

Load Balancing SymmetricDS Pro

For most of our large clients where SymmetricDS is playing a mission critical role in their organization, our customers take advantage of SymmetricDS Pro's out of the box capabilities to be load balanced. While SymmetricDS does a great job with hands off recovery in cases of hardware or infrastructure failure, most clients want as little downtime as possible. They simply don't want a single point of failure in their synchronization scenario. The good news is, with SymmetricDS Pro, load balancing is simple and straight forward.

Using Wildcards to Sync Database Tables

Quickly select and dynamically add tables to database synchronization using wildcard characters. This powerful feature can save time during configuration and even eliminate the need to make changes to configuration in the future. Since data capture triggers can be created from a schedule or on-demand programmatically, wildcard characters open up the possibility of new applications, such as using SymmetricDS database replication in Platform As A Service (PaaS) where new tables created by a client are automatically replicated between high availability servers. This article will demonstrate using wildcard characters to sync some tables while ignoring others.

SymmetricDS: Behind the Scenes

We have received many inquiries about the architecture of SymmetricDS lately.  I think the user’s guide does a nice job of laying out how to implement and configure SymmetricDS, but we have noticed (after taking a step back) that it doesn’t provide a concise, technical overview.   You can probably piece everything together from the guide, but it is probably worth some effort to describe how SymmetricDS works under the covers.  We’ll be updating the documentation with this information in the near future.

SymmetricDS 2.2.0 Released

SymmetricDS 2.2.0 is a minor release that brings 15 bug fixes, 8 improvements, and 5 new features.  Some highlights include:

  • The incoming data loader was changed to use a single connection to eliminate contention with a nested transaction and reduce the connection pool requirements. 
  • The purge job that cleans up the runtime tables is now three separate jobs that can be scheduled independently.
  • A new query plan is being used to route and batch data changes that is more efficient.

This release also includes a new project organization and reduced library dependencies in preparation for small footprint clients.  We've created a new Mobile Development forum to discuss plans for an upcoming mobile implementation.
