OceanBase Database vs Oracle Real Application Clusters

OceanBase Database is a distributed database for transactional, analytical, and AI workloads in one system. Built-in compatibility with Oracle and MySQL is intended to simplify migration. Deployment choices include the open-source Community Edition, self-hosted Enterprise, and fully managed OceanBase Cloud across cloud providers. Documentation describes high availability and disaster recovery at node, data-center, and region levels. Linux installation packages are listed for Alibaba Cloud Linux, CentOS, Red Hat, Ubuntu, Debian, and Anolis OS. Docker deployment can be used on Windows and macOS, though the documentation cautions that this method has not been validated at scale. A standalone instance can be used for learning; production environments require at least three servers. Community Edition is free and includes full kernel capabilities. Enterprise pricing is available on request. Security features include role and permission management, network whitelists, encrypted communication, transparent data encryption, and SQL auditing, but Community Edition does not support security audit.
