Overview
Huangpu District Health Affairs Management Center | Public Healthcare Administration
Country: China
Industry: Healthcare / Public Service
Solution: Info2soft Cloud Migration + Oracle RAC Upgrade + DR Protection
The center operates multiple critical systems on VMware, including smart reminders, Wanda applications, and Convenient Healthcare 2.0. To meet national localization requirements, these systems needed to migrate to Tianyi Cloud with minimal impact on operations. Additionally, the center’s Oracle RAC database (≈20TB) powering the Wanda application required a smooth upgrade due to version compatibility issues while ensuring disaster recovery.
Customer Challenge
- Migrate VMware-based systems to Tianyi Cloud without business disruption.
- Handle Oracle RAC database upgrade with large data volume (~20TB) and version compatibility issues.
- Ensure rollback and disaster recovery capabilities throughout the migration and upgrade.
I2 Solution
Cloud Migration: Adopted hot migration mode to Tianyi Cloud without changing the existing architecture. A scheduled cutover window was used to pause business systems, ensuring no incremental data was generated during final switchover.
Database Upgrade Process:
- Conducted full database information survey and planning.
- Replicated local Oracle RAC to Tianyi Cloud.
- Performed pre-switch testing by pointing applications to the cloud database for verification.
- After validation, reverted applications back to the local database.
- Carried out local RAC upgrade with rollback protection.
- Disaster Recovery: Finalized cloud RAC as a disaster recovery database, maintaining synchronization with production for ongoing protection.
Solution Effects
- Achieved smooth migration to Tianyi Cloud, enabling virtualization platform localization with minimal downtime and resource use.
- Completed Oracle RAC upgrade safely with full rollback plan, ensuring system integrity and business continuity.
- Established a disaster recovery database on the cloud, providing continuous protection against failures.
