USING DIRECT MEMORY ACCESS FOR PERFORMING DATABASE OPERATIONS BETWEEN TWO OR MORE MACHINES

摘要

Direct memory accessed is used to perform database operations between two or more machines. A first segment of memory is allocated for a second machine, where at least one of the first machine and second machine is a database server. During performance of a database operation that involves the transfe r of data from the second machine to the first machine, data in the first segment of memory is buffered in response to the second machine writing the data to a second segment of memory on the second machine.
