UK Bank – CDC Replication Enhancements

Client Summary

The client is a major UK bank using IBM VSAM and Oracle systems, with critical CDC applications replicating data into Kafka to meet Tier0/Tier1 resilience standards. These applications are essential for real-time operations and data integrity across their infrastructure.

The Challenge

The bank required enhancements to its CDC environment to meet updated operational requirements. They also needed real-time monitoring and validation of replication performance to ensure data consistency, as well as targeted training on critical aspects of the CDC system.

Objectives

The objectives were to implement time-critical enhancements, ensure replication integrity, and provide highly-customised training, all delivered within tight customer deadlines.

Technical Highlights

The project involved complex replication from IBM VSAM and Oracle to Kafka, with performance monitoring and validation scripts developed to maintain resilience standards.

Our Approach

Custom scripts were developed to monitor replication and validate data in real time. Enhancements and modifications were implemented quickly to meet new operational requirements. Targeted, hands-on training was delivered to key teams to ensure they could manage the CDC environment effectively.

Outcome and Benefits

The enhancements were completed successfully within the required timeframe. Replication performance was fully validated, and the bank staff gained practical knowledge of critical CDC features, ensuring continued operational resilience.

Lessons Learned

Rapid development and deployment of customised scripts, combined with focused training, can meet stringent deadlines while maintaining high operational standards.

Follow-Up

The client now has enhanced CDC monitoring and validation processes, with staff trained to manage future changes independently.
