    摘要: A system and method for a relational database system for identifying star joins in a query and for breaking the query down for bitmap ANDing. The fact table of the star join is located, and cycles between and within dimension tables are broken. Then, the minimal set of tables necessary to execute the star join is identified, and the dimension tables that should appear in the bitmap ANDing plan are also identified. A bitmap ANDing plan is then generated, or, if the query does not qualify for bitmap ANDing, a conventional execution plan is generated.

    摘要: A database management system in which a plurality of nodes form a database instance, each node including a communication manager for dynamically configuring inter-nodal communication resources. The communication manager receives communication resource allocation requests from clients or a self-tuning algorithm. A resource self-tuning mechanism allocates or de-allocates memory blocks used for communication resource elements dynamically in real time without cycling the instance. Memory blocks are de-allocated asynchronously by placing associated communication resource elements in quarantine until all communication resource elements associated with the memory block are quarantined.
