How ICBC Migrated Its Corporate Wealth Management System to OceanBase for High Availability
ICBC's corporate wealth management platform, which supports trillion‑yuan assets for enterprise clients, has been migrated from a mainframe to a distributed OceanBase cluster, boosting high availability, ensuring business continuity, and cutting costs while maintaining performance and stability.
According to Alipay Technology, the Industrial and Commercial Bank of China (ICBC) corporate wealth management system is now running on OceanBase.
The system is a critical banking business platform supporting corporate clients with assets at the trillion‑yuan level and previously operated on a large mainframe architecture.
As the bank accelerates its digital transformation, this system became the first to undergo distributed transformation based on OceanBase.
After a three‑month observation and verification period, ICBC, Ant Group's OceanBase, and Alibaba Cloud technical teams jointly formulated a host migration plan, and the system was officially launched in September.
In this collaboration, OceanBase built a distributed cluster spanning two locations and three data centers for ICBC, using a five‑replica plus primary‑backup mode to enhance high availability, provide strong business continuity, and effectively reduce costs while maintaining performance and stability.
