Case Study: Payment Processing Company Achieves 100% Uptime Migrating and Upgrading Database to Exadata
Monday March 24, 2025 10:30am - 11:15am MDT
Room 213
Learn how one of the largest payment processing companies migrated its mission-critical databases to the latest Exadata platform with zero downtime. During the migration, we upgraded databases from Oracle 12c (12.1) to Oracle Database 19c. This session will cover technical architecture details, how ultra-high availability was achieved, lessons learned, and, most importantly, how we mitigated risks related to performance.

Numerous challenges were overcome as the databases served a global financial client base. The production database migration to the Exadata environment was completed with zero downtime architecture, using a "live cutover" while continuing to process application data. The Exadata clusters consisted of two sets of ten-node RAC compute nodes across two data centers.

Technologies leveraged include:
- Datapump
- GoldenGate
- Real Application Testing
- 10-Node RAC Cluster
- Global Data Services
- 10-Node RAC Cluster Exadata replicating data to another 10-Node RAC Cluster Exadata
