  • Aware, Workstation-Based Distributed Database System
    THE ARCHITECTURE OF AN AUTONOMIC, RESOURCE- AWARE, WORKSTATION-BASED DISTRIBUTED DATABASE SYSTEM Angus Macdonald PhD Thesis February 2012 Abstract Distributed software systems that are designed to run over workstation machines within organisations are termed workstation-based. Workstation-based systems are characterised by dynamically changing sets of machines that are used primarily for other, user-centric tasks. They must be able to adapt to and utilize spare capacity when and where it is available, and ensure that the non-availability of an individual machine does not affect the availability of the system. This thesis focuses on the requirements and design of a workstation-based database system, which is motivated by an analysis of existing database architectures that are typically run over static, specially provisioned sets of machines. A typical clustered database system — one that is run over a number of specially provisioned machines — executes queries interactively, returning a synchronous response to applications, with its data made durable and resilient to the failure of machines. There are no existing workstation-based databases. Furthermore, other workstation-based systems do not attempt to achieve the requirements of interactivity and durability, because they are typically used to execute asynchronous batch processing jobs that tolerate data loss — results can be re-computed. These systems use external servers to store the final results of computations rather than workstation machines. This thesis describes the design and implementation of a workstation-based database system and investigates its viability by evaluating its performance against existing clustered database systems and testing its availability during machine failures. ACKNOWLEDGEMENTS I’d like to thank my supervisors, Professor Alan Dearle and Dr Graham Kirby, for the opportunities, the support, and the education that they have given me.

  • Magic Quadrant for Data Warehouse Database Management Systems
    Magic Quadrant for Data Warehouse Database Management Systems Gartner RAS Core Research Note G00209623, Donald Feinberg, Mark A. Beyer, 28 January 2011, RV5A102012012 The data warehouse DBMS market is undergoing a transformation, including many acquisitions, as vendors adapt data warehouses to support the modern business intelligence and analytic workload requirements of users. This document compares 16 vendors to help you find the right one for your needs. WHAT YOU NEED TO KNOW Despite a troubled economic environment, the data warehouse database management system (DBMS) market returned to growth in 2010, with smaller vendors gaining in acceptance. As predicted in the previous iteration of this Magic Quadrant, 2010 brought major acquisitions, and several of the smaller vendors, such as Aster Data, Ingres and Vertica, took major strides by addressing specific market needs. The year also brought major market growth from data warehouse appliance offerings (see Note 1), with both EMC/Greenplum and Microsoft formally introducing appliances, and IBM, Oracle and Teradata broadening their appliance lines with new offerings. Although we believe that much of the growth was due to replacements of aging or performance-constrained data warehouse environments, we also think that the business value of using data warehouses for new applications such as performance management and advanced analytics has driven — and is driving — growth. All the vendors have stepped up their marketing efforts as the competition has grown. End-user organizations should ignore marketing claims about the applicability and performance capabilities of solutions. Instead, they should base their decisions on customer references and proofs of concept (POCs) to ensure that vendors’ claims will hold up in their environments.

Each server has separate own database instance and these all act as instance of single database for the external network access on the unique virtual IP address. The architecture of the RAC is provides fault tolerance and a great power of treatment. Oracle RAC provides several features in any database operation of the enterprise level for example the scalability, availability, load balancing and failover. The purpose of this study is to serve as a quick reference guide to the installation of management and operation of the Oracle Cluster-ware Real Application Cluster (RAC) database. This feature is initially targeted for the technical staff mainly for DBA Admins of the system. Keywords: RAC, Shared Storage, SAN, Cluster-ware, Oracle ASM, Oracle Kernel. 1. INTRODUCTION systems in the cloud and enterprise software products. Oracle is the world's leading supplier of software for information Cluster database instances are common challenging for management, but is best known for its refined products for each vendor application is presenting its own architecture relational databases.
