Active-Active Data Replication in Real-Time for a Natural Gas Operator

Using Oracle GoldenGate

Gaz System is a designated natural gas transmission system operator in Poland. They decided to work with Goldenore to ensure business continuity and uninterrupted functioning of systems during upgrades.

The project challenge was to build high availability infrastructure to provide two-way data synchronization between data centers with critical metering databases.

Business Perspective


  • The billing system is business critical, and its performance can impact revenue. ​The system was highly vulnerable due to relying on a single database.
  • Possible negative consequences included:​ loss of vital information necessary for billing clients​, financial losses caused by unavailability of the billing system, security non-compliance ​


  • The risk of losing data from the billing system was instantly eliminated. The highest and most advanced level of security was achieved with a two-way exchange of data between redundant databases (Oracle Platinum)​.
  • Business continuity is ensured in case of database failure with an active replica​ keeping the billing system always online.

The Architecture

Implementing real-time data replication can solve current business continuity and data access problems, and be a starting point in a journey to an entirely data-driven enterprise.
