Case Study: Heilongjiang Mobile Co., Ltd. cuts annual maintenance costs, slashes power use by 67%, and doubles service-quality analysis speed with Oracle Exadata

Heilongjiang Mobile Drastically Cuts Costs with Oracle Engineered Systems

Heilongjiang Mobile Co., Ltd., a China Mobile subsidiary serving over 10 million 4G users across Heilongjiang province, needed a high-performance, scalable database platform to support rapid service growth, simplify maintenance, and meet energy-saving and emission-reduction targets. The company’s challenge was to consolidate three legacy databases, lower operating and maintenance costs, and improve the speed and availability of business-critical telecom services and performance analysis.

Heilongjiang Mobile consolidated its disparate databases onto a single Oracle Exadata Database Machine and went live in three months, gaining a preintegrated hardware‑software platform with Oracle RAC, Diagnostics and Tuning packs. The change cut annual maintenance costs by about US$30,000, reduced data center power and cooling needs by 67%, doubled the speed of service-quality analysis (OLTP/OLAP), improved availability and faster problem resolution, and provided easy capacity scaling as services grow.
