Why Data Replication Rocks!

Data is a lot like music: We want it when we want it, and technology has evolved to support that demand.  

  • People embraced CDs, so they could quickly find the best songs and skip the ones they didn’t like.
  • MP3 players gave them portable access to a good-sized chunk of their music collection.
  • Today, of course, music is data — with cloud-based offerings delivering endless choices, anywhere, anytime, on demand.

Failing to use data replication technology is like struggling with a phonograph in this Spotify era. But we’re about to get you up to speed.

By the time you finish reading this post, you’ll understand why simple-to-use data replication technology is the key to becoming a DBA rock star.

Why near-real-time replication is music to the modern DBA’s ears

There are three reasons why near-real-time replication reduces the wait and increases user satisfaction:

1.  Availability

In the old days, high availability was a nice-to-have. Now that your customers and users are on your databases on internet time, high availability is a must-have.

When you plot a course for high availability, you have to take into account three big sandbars: planned outages, unplanned outages and spikes in system load. In all three cases, a specific method of near-real-time replication lessens the strain on databases while ensuring valuable data is always available.

2. Scalability

Users have come to expect rapid response from your applications. Their unlimited hunger for performance trickles down to the underlying databases, where it meets very real hardware limitations. CPU, memory, network and storage can scale only so far.

Near-real-time replication provides one or more copies of databases with no distance limitations. It helps DBAs eliminate the single point of failure, optimize for different workloads, offer geographic flexibility, consolidate databases and spread the user load across multiple databases and data centers.

3. Near-real-time data integration

Data-driven enterprises must not only collect huge amounts of data, but also integrate it from numerous sources while ensuring that it is consistent, even when stored on different systems in different places. Integration tools aggregate the data in these different silos and make it available for operations and analysis.

Reducing the wait is a matter of integrating and reconciling multiple sources of data into a single source of truth with as little delay as possible. Users (and their managers) are satisfied when they are confidently working with data on a replication target that is as close to real-time as possible to production data. This technology gives you the power to provide that.

Next steps

For those three reasons (and several others) it makes sense to replicate data from Oracle databases to other targets and have users work on it there. Instead of making your paying customers wait, replicate your data where they can analyze and report to their heart’s content. Replication is also useful for archiving, data warehousing and minimizing downtime during migrations. If a near-real-time copy of your Oracle data in a separate Oracle replica is too expensive, why not explore the idea of a SQL Server data warehouse that lets you cost-effectively offload analysis, reporting and other operations from your Oracle production databases? Our SharePlex replication solution gives you the flexibility to choose the target replica system that is appropriate for the business case and ultimately the consumers of the data.

Replicate from Oracle to a more economical and potentially easier-to-manage platform like SQL Server and experience less frustration when support is required. Offloading database activities to a SQL Server replica will leave more processing power and faster response times for your Oracle users. Users on the SQL Server target will enjoy near-real-time data on an instance that is tuned specifically for the purpose of reporting, analytics and other database activities while the Oracle production system remains tuned for online transaction processing (OLTP). 

In addition, SharePlex can be used to completely migrate an Oracle database to SQL Server without taking users offline during the migration process. A SQL Server target replica could be used to accomplish archiving or serve as a data warehouse that replication maintains in near-real time with all or a subset of data from one or multiple Oracle instances.

Strike the right chord with your users by delivering the data they want when they want it. With the right data replication technology in place, you’ll quickly find you have a lot more time to work on your digital playlists.
