  • Query parallelism in a shared data DBMS system
    Patent number: 5692174
    Abstract: A system and method for a computer system having a plurality of DBMS providing a coordinating and assisting function. If a DBMS performs a coordinating function, it is referred to as a coordinating DBMS. If a DBMS performs an assisting function, it is referred to as an assisting DBMS. Each coordinating DBMS receives a query from a user application, decomposes the query into multiple parallel tasks, and allocates the parallel tasks to all of the DBMSs in the system. Each assisting DBMS receives one or more parallel tasks from a coordinating DBMS, executes the parallel tasks and returns the results to the coordinating DBMS. The coordinating DBMSs and assisting DBMSs access one or more storage devices. Furthermore, the present invention comprises a system and method for dynamically disabling a parallel mode on the coordinating DBMSs and the assisting DBMSs.
