Middleware -based Database Server Allocation of Distributed Database on PC Cluster Systems

Abstract

The study seeks to provide a distributed database using the Middleware-based Database Server Allocation (MDSA). The MDSA allocates available servers to cluster computers and search for the best cluster that caters to a query. There were eight experiments performed using MDSA and were compared to the sequential and random search method, which include controlled CPU utilization and random CPU utilization in terms of access time, single query and multiple queries. Experiment al results show ed that with MDSA, there is a reduction of data response time under varying number of nodes, ranging from 1 to 8 clustered servers.
