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 transfer 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.
