OceanBase Migration Service (OMS) supports data interaction between OceanBase Database and homogeneous or heterogeneous Relational Database Management Systems (RDBMSs). It provides online data migration and real-time synchronization of incremental data.
OMS provides a visualized and centralized management platform. Data can be migrated in real time after simple configurations, and the resource usage and performance impact on the source database and business systems are slight. OMS aims to implement highly efficient real-time data migration and synchronization from homogeneous or heterogeneous databases to OceanBase Database with the lowest cost and risk. OceanBase Migration Service (OMS) supports data migration from various types of relational databases to OceanBase Database. The OMS features vary slightly with the source database.
In addition, OMS can migrate data to OceanBase Database seamlessly without service interruption. OMS can enable a reverse data synchronization link before business applications are switched to OceanBase Database, and then re-establish the primary/secondary relationship. Through the link, all data changes on the OceanBase Database will be synchronized to the source database in real time, implementing data consistency during database switchback in an emergency. This feature greatly reduces business migration risks, helping enterprise users build a database architecture with high availability and high reliability.
OMS also enables millisecond-level real-time mass data replication between heterogeneous IT infrastructures. Therefore, OMS can be applied to multiple scenarios, such as data migration, inter-city data backup for disaster recovery, emergency systems, real-time data synchronization, disaster recovery, and database upgrade and migration. OMS can migrate and synchronize data without affecting or interrupting your business applications. It also ensures data integrity and transaction consistency.
