On June 15, 2025, Sense Bank, in collaboration with CS, successfully completed a critical cross-platform migration project of the industrial database of the B2 Core Banking System (CBS B2) on Oracle Database 19c to a modern x86-based server infrastructure running Oracle Linux on the HPe operated by Sophela platform.
The project was implemented with minimal system downtime, ensuring uninterrupted support for business processes and maintaining a high level of system availability. The new server platform not only guarantees stable operation of the CBS but also lays the foundation for future scalability and optimization of the IT infrastructure.
The main objectives of the project were:
- Minimizing the downtime of the CBS B2 database.
- Migrating a large volume of mission-critical data while preserving data integrity.
- Ensuring sufficient system performance.
- Setting up a standby database during the migration process.
The project leveraged a combination of Oracle technologies and best practices, including Cross Endian Platform Migration using Full Transportable Data Pump Export/Import and RMAN Incremental Backups, along with proprietary solutions to accelerate data transfer, reduce downtime, and maintain database performance before the full collection of up-to-date statistics. All operations were carried out under strict access control and data encryption, minimizing any information security risks.
As a result of the migration, a target database of over 50 TBytes was successfully deployed with a downtime of up to 5 hours, simultaneously with the deployment of the StandBy database in the bank’s hybrid server infrastructure.
Serhiy Belozyorov, Director of the Department for the Development of Centralized Information Systems, Sense Bank:
This project marks an important step in the transformation of our IT infrastructure. We preserved the stability of critical services while opening up new opportunities for the development of banking services.
