Abstract
A method and program for use with a massively parallel processor (MPP) system or a distributed computer system for providing a physical design layout database across several nodes of the system. A user inputs a first datafile representing the physical configuration of the distributed processor system, and inputs a second datafile representing application tablespaces and/or database system files to be stored in the distributed processor system. The program optionally assigns the tablespaces in the second datafile to the physical configuration of the distributed processor system as specified in the first datafile and per the number of nodes, number of disks per node, and the size of the disks. The user may optionally use the physical design layout of the program, may change a portion of the intermediate physical design layout, or may provide the entire physical database design layout, as desired. The program generates a logical volume map for the tablespaces distributed over the distributed processor system, and further generates scripts to implement the tablespace structure into a physical database.
