Case Study: Chosun Ilbo achieves 10x faster daily billing and improved satisfaction with Oracle Exadata

Chosun Ilbo Completes Daily Billing 10x Faster, Improves Employee Satisfaction, and Supports Future Growth

Chosun Ilbo, a major Korean media company, was struggling with aging legacy database servers that had reached 100% CPU usage at peak times, limited storage, and long 11-hour downtime windows that slowed daily billing across 1,200 branch offices and disrupted online services. The company chose Oracle Exadata, along with Oracle GoldenGate, to modernize its data warehouse and support its growing online and mobile news business.

Oracle Exadata consolidated eight databases onto a scalable, secure platform, while Oracle GoldenGate enabled seamless, real-time data migration with no downtime. As a result, Chosun Ilbo cut CPU usage from 100% to 30%, reduced data migration and loading time from up to 12 hours to less than 2 hours, and enabled branch offices to complete daily billing about 10x faster—roughly 1 hour instead of 11 hours—while improving service stability, employee satisfaction, and future growth capacity.
