  • Oracle database filesystem
    International Conference on Management of Data, 2011
    Co-Authors: Krishna Kunchithapadam, Wei Zhang, Amit Ganesh, Niloy Mukherjee
    Abstract:

    Modern enterprise, web, and multimedia applications are generating unstructured content at unforeseen volumes in the form of documents, texts, and media files. Such content is generally associated with relational data such as user names, location tags, and timestamps. Storage of unstructured content in a relational database would guarantee the same robustness, transactional consistency, data integrity, data recoverability and other data management features consolidated across files and relational contents. Although database systems are preferred for relational data management, poor performance of unstructured data storage, limited data transformation functionalities, and lack of interfaces based on filesystem standards may keep more than eighty five percent of non-relational unstructured content out of databases in the coming decades. We introduce Oracle Database Filesystem (DBFS) as a consolidated solution that unifies state-of-the-art network filesystem features with relational database management ones. DBFS is a novel shared-storage network filesystem developed in the RDBMS kernel that allows content management applications to transparently store and organize files using standard filesystem interfaces, in the same database that stores associated relational content. The server component of DBFS is based on Oracle SecureFiles, a novel unstructured data storage engine within the RDBMS that provides filesystem like or better storage performance for files within the database while fully leveraging relational data management features such as transaction atomicity, isolation, read consistency, temporality, and information lifecycle management. We present a preliminary performance evaluation of DBFS that demonstrates more than 10TB/hr throughput of filesystem read and write operations consistently over a period of 12 hours on an Oracle Exadata Database cluster of four server nodes. In terms of file storage, such extreme performance is equivalent to ingestion of more than 2500 million 100KB document files a single day. The set of initial results look very promising for DBFS towards becoming the universal storage solution for both relational and unstructured content.

  • Exadata Performance Metrics
    Expert Oracle Exadata, 2020
    Co-Authors: Martin Bach, Kerry Osborne, Randy Johnson, Karl Arao, Andy Colvin, Frits Hoogland, Tanel Poder
    Abstract:

    Oracle Exadata is a big step forward from the traditional database server architecture; however, despite all the innovative features, it is still running the standard Oracle Database software. Most of the well-versed database performance rules still apply, with the addition of some that recognize the advantage of Exadata functionality like Smart Scans, cell join filtering, and the Flash Cache. In this chapter, you can read more about the Exadata-specific and related performance topics, metrics, and some relevant internals.

  • expert Oracle Exadata
    2011
    Co-Authors: Kerry Osborne, Randy Johnson, Tanel Pder
    Abstract:

    Throughout history, advances in technology have come in spurts. A single great idea can often spur rapid change as the idea takes hold and is propagated, often in totally unexpected directions. Exadata embodies such a change in how we think about and manage relational databases. The key change lies in the concept of offloading SQL processing to the storage layer. That concept is a huge win, and its implementation in the form of Exadata is truly a game changer. Expert Oracle Exadata will give you a look under the covers at how the combination of hardware and software that comprise Exadata actually work. Authors Kerry Osborne, Randy Johnson, and Tanel Pder share their real-world experience, gained through multiple Exadata implementations with the goal of opening up the internals of the Exadata platform. This book is intended for readers who want to understand what makes the platform tick and for whom"how" it does what it is does is as important as what it does. By being exposed to the features that are unique to Exadata, you will gain an understanding of the mechanics that will allow you to fully benefitfrom the advantages that the platform provides. Will changes the wayyou think about managing SQL performance and processing Provides a roadmap to laying out the Exadata platform to best support your existing systems Dives deeply into the internals, removing the black box mystique and showing how Exadata actually works What youll learn Configure Exadata from the ground up Optimize for mixed OLTP/DW workloads Migrate large data sets from existing systems Connect Exadata to external systems Support consolidation strategies using the Resource Manager Configure high-availability features of Exadata, including real application clusters (RAC) and automatic storage management (ASM) Apply tuning strategies utilizing the unique features of Exadata Who this book is for Expert Oracle Exadata is for database administrators and developers who want to understand what makes Exadata unique so that they can take advantage of all the platform has to offer. It is also for anyone who needs to plan and execute migrations of systems to the Exadata platform. Finally, the book will be invaluable to those who support and maintain such systems.
