Dameng’s data sharing cluster software (DMDSC) adopts DM8’s new technology and boasts high availability and extensibility, making it a core piece of technology in the database support network computing environment.
DMDSC is a multi-instance single database system that is primarily comprised of its database and database instances, shared storage, local storage, communications network and the DMCCS cluster control software. Multi database instances can gain simultaneous access to or modify the data in the same database. Users can log into any random database instance within the cluster to gain comprehensive database services. There are only single data files, on-line logs and control files within the cluster system, meaning that no matter how many nodes there are, these nodes all evenly use these files, and those files are then saved into the shared storage.
DMDSC technology can provide support for low-cost hardware platforms and get high-quality services from them, as well as reach or even overreach the levels of usability and scalability that high-end hardware platforms can provide. By remarkably reducing management costs and providing outstanding management flexibility, Dameng offers strong support for an enterprise’s grid environment.
DMDSC is designed for use with applications that have high availability and scalability. By protecting applications from hardware and software failures, it can provide system availability that ensures continuous access to data. Its horizontal and vertical scaling features form a platform, which allows enterprises to extend their business from any level. An application’s development and management, as well as change of management, thus becomes simpler and that then accordingly reduces an enterprise’s overall costs.
