    • distributed database management system implemented on a cluster of computers. The cluster including disks organized as data nodes. The data nodes being locally connected to one or more computers in the cluster. The distributed database management system includes a distributed database manager layer having a lock manager, a resource manager, and an architecture manager. The lock manager serializes access to the data nodes in the cluster. The resource manager maintains a data representation of the resources of each computer in the cluster and makes the data available to other computers in the cluster to facilitate access to the resources by the other computers. The architecture manager defines logical ownership relationships between data nodes and computers in the cluster to permit the architecture of the database to be dynamically reconfigured to provide improved performance.
    • 分布式数据库管理系统在一组计算机上实现。 集群包括组织为数据节点的磁盘。 数据节点本地连接到集群中的一台或多台计算机。 分布式数据库管理系统包括具有锁管理器,资源管理器和架构管理器的分布式数据库管理器层。 锁定管理器将访问集群中的数据节点序列化。 资源管理器维护集群中每台计算机的资源的数据表示,并使数据可用于集群中的其他计算机,以便其他计算机访问资源。 架构管理员定义集群中数据节点和计算机之间的逻辑所有权关系,以允许动态重新配置数据库的体系结构以提供改进的性能。

    • A method for implementing distributed database management system operations on a computer cluster. The method includes defining ownership relationships between a plurality of computers in the computer cluster and a plurality of data nodes in the computer cluster, wherein a distributed database management system operation can be directly carried out by a first computer only on those data nodes owned by the first computer. The method further includes monitoring database usage characteristics. The method further includes carrying out a re-architecture step in response to the database usage characteristics by redefining ownership relationships to improve the efficiency of the distributed database management system operations.
