In an era where digital banking must run with the precision of a heartbeat, one of the leading banks in Southern India had to modernize its core database systems to stay compliant, scalable, and customer-centric. Entrusting this high-stakes transformation to Clover Infotech, the bank embarked on a journey to upgrade its mission-critical Oracle 11g databases to Oracle 19c — and the results have been nothing short of transformative.
The Challenge: Critical Systems, Zero Downtime Tolerance
The bank’s databases support essential digital services like UPI, Internet Banking, and FasTag transactions. Any disruption would have immediate repercussions on customer experience and regulatory compliance. Complicating the challenge further, these databases were running on aging AIX infrastructure, which was both costly and nearing end-of-life.
Adding to this complexity were evolving Reserve Bank of India (RBI) regulations, cybersecurity mandates, and the need for real-time observability — all of which required a secure, scalable, and compliant environment with minimal operational risk.
The Solution: Cross-Platform Migration with Oracle GoldenGate and OEM
Clover Infotech executed a cross-platform migration from AIX to Linux and upgraded the databases to Oracle 19c, ensuring near-zero downtime with Oracle GoldenGate replication. The transition was tightly governed and involved OS-level hardening, VAPT remediation, and OEM dashboard integration to meet Center for Internet Security (CIS) and RBI compliance.
With Active Directory integration and automated patching workflows, bank’s new environment is now resilient, secure, and future-ready.
The Impact: High Performance, Lower TCO, Stronger Compliance
The outcomes speak for themselves:
- 99.99% uptime maintained during and post-upgrade due to Golden Gate-powered near-zero downtime switchover.
- 40% performance improvement in transaction-heavy applications like UPI and Internet Banking, driven by larger database sizing and 19c performance tuning.
- 100% compliance readiness with integration of CIS dashboard in OEM, and VAPT remediation aligned with RBI audit requirements.
- Lower TCO: Migration from AIX to Linux significantly reduced infrastructure and licensing costs.
- Reduced Incident Volume: Post-upgrade, support tickets dropped significantly due to increased stability, patching, and OEM-based monitoring.
- Improved Diagnostic Capabilities: OEM integration now provides real-time alerts, root-cause analysis, and compliance dashboards, enhancing observability and response time.
Comparison to Prior State: Earlier, the bank operated on end-of-life Oracle 11g with a legacy AIX platform — posing risks of non-compliance, performance degradation, and higher CapEx/OpEx. The environment lacked automated diagnostics and required extensive manual effort for audits and patching.
Business Transformation: The upgraded platform now enables proactive IT operations, secure banking service delivery, and scalable digital infrastructure. It positions the bank to adopt future Oracle innovations seamlessly, while reducing technical debt.
By aligning IT modernization with regulatory and business goals, Clover Infotech helped the bank achieve lasting value realization, enhanced customer experience, and long-term ROI.
Looking Ahead: Scaling New Digital Frontiers
Today, the upgraded Oracle 19c environment powers the bank’s 24×7 digital banking operations and serves as the bedrock for future innovations, including autonomous database adoption and enhanced lifecycle automation. This transformation has not only fortified the bank’s operational resilience but also positioned it to scale confidently in a highly regulated, fast-evolving digital banking landscape.
