Worried about core system migration errors? GBase Database enables seamless Oracle-to-domestic migration.

Published on 2025-10-20

During the adoption of domestic IT systems, core system migration is the top concern for enterprises. Those long-running Oracle/MySQL systems carry a heavy load of business logic; any misstep during migration could disrupt business continuity. GBase database, with its mature compatibility and migration solutions, makes this process far more manageable.

With over two decades of deep expertise in database technology, GBase has always refused to chase "paper performance gimmicks," instead embedding the principle of "minimal code changes, minimal downtime, and minimal risk" into its core design philosophy. The foundation for all this is the compatibility capability refined over twenty years.

Compatibility:
More than just "compatible" — it means minimal code changes

For enterprises, "compatibility rate" is never just a cold number; it represents the tangible value of fewer code modifications and less manpower. This has always been the core goal of GBase 8s database iterations.

For Oracle scenarios, GBase 8s achieves over 90% syntax compatibility and nearly 95% PL/SQL compatibility: common conditional statements, cursors, autonomous transactions run without modification; Oracle-specific features such as dblink cross-database connections and flashback data recovery are fully adapted. More importantly, the "database fundamentals" — data types, partitioned tables, materialized views, triggers, scheduled tasks — require no redesign during migration, and most of the original business logic lands unchanged.

For MySQL users, GBase 8s compatibility exceeds 85% and continues to approach 90%: commonly used syntaxes such as partitioned tables, ROLLUP statistics, session variables, natural joins are all seamlessly supported, requiring no additional rework from the team.

The value of this compatibility is clearly visible: user transformation costs are reduced by approximately 50%, and operational costs drop by nearly 30%. No more overtime for code modifications, no need for extra manpower for adaptation — this is the "ease" that migration should bring.

MTK + RTSync:
A "dual assurance" for migration, controlling risks throughout

Compatibility alone is not enough; the "stability" and "speed" of migration are equally critical for enterprises. GBase 8s database provides a complete set of supporting tools for the migration process, establishing end-to-end protection from upfront risk assessment to smooth cutover.

1. MTK: Full-process visualization, ensuring "stability" before, during, and after migration
MTK covers the entire flow of "multi-source access – task management – migration execution – assessment monitoring – exception recovery," supporting migration from mainstream databases such as Oracle and MySQL. Its core advantage is the "assess–monitor–adapt" trinity of risk control:

  • Before migration: Dual assessments to avoid pitfalls. The migration assessment performs a full DDL simulation migration, calculates object success rates, and generates a detailed error report to identify syntax incompatibility, insufficient permissions, and other issues in advance. The resource assessment collects metrics such as disk, memory, and network latency to predict migration duration, helping enterprises plan resources.

  • During migration: Real-time progress visibility. The visual interface displays data volume, completion rate, and remaining time in real time, and allows precise drill-down by object name, type, and status.

  • After migration: 100% data verification. Supports multi-dimensional comparison across fields, totals, and content to ensure no data tampering or truncation.

2. RTSync: Multi-mode real-time synchronization, solving the "downtime cutover" pain point

RTSync focuses on "imperceptible business cutover, multi-scenario data flow, and high-availability synchronization," supporting three core modes for seamless source-to-target integration:

  • Incremental sync: Captures insert, update, and delete operations on the source database in real time and synchronizes to GBase 8s, solving the "downtime cutover" pain point. Supports "full database sync" or "table-level sync (all or selected columns)" to meet fine-grained requirements.

  • File relay: Synchronizes source data to local/FTP files, suitable for "offline backup, cross-system indirect sync" scenarios; the files can be forwarded later.

  • Combined mode: First synchronizes to files (relay), then incrementally syncs from the files to the target database, suitable for scenarios where source and target networks are isolated, balancing security and real-timeness.

From "MTK assessment and adaptation" to "RTSync sync testing" and then to "smooth cutover go-live," GBase 8s database provides a complete closed-loop migration process. There’s no need to "gamble" on the success of the go-live; just follow the steps, and migration becomes a "controlled upgrade."

Real-World Proof:
Conquering Migration Challenges Together with Customers

All the talk pales in comparison to real-world cases. Throughout our journey, GBase 8s database has worked with customers from various industries to successfully tackle one core system migration challenge after another.

Case 1: A power grid metering system in Southwest China

A power grid metering system in Southwest China originally ran on Oracle, with 300,000 lines of PL/SQL code alone, including 130 stored procedures/functions, 140 packages, as well as 2,000 tables and 1,000 views. This directly affected electricity supply for millions of users, leaving no room for error.

The project was carried out in close collaboration with the power grid company: thanks to the high compatibility of GBase 8s database, most code required no modification. By using MTK to preemptively identify potential issues and RTSync to ensure data synchronization, the system has been running stably since go-live.

Case 2: Huaxia Bank’s Financial Electronic Account System

Huaxia Bank’s financial electronic account system was originally built on MySQL, containing over 700 stored procedures/functions, 30+ triggers, 100+ tables, and 200+ views. For a bank, the "stability" of the account system is as important as the "speed of deployment."

Thanks to the high compatibility of GBase 8s with MySQL, the system was migrated with almost "zero application change": adaptation testing was completed in two weeks, and no operational issues have arisen since go-live.

As a domestic database provider, GBase firmly believes that success in IT application innovation substitution is never just about swapping databases; it’s about making business run more stably after the change. GBase 8s database is committed to providing comprehensive support for enterprises facing core system migration challenges, working together to minimize migration risks and make business operations more stable and reliable.
