不要乱讲啊。我把搜集来的东东方这里看看。
ORACLE DATABASE – THE NEXT VERSION
The next version of the Oracle Database has been designed to meet two key goals –reducing the cost of manageability
and delivering increased performance for all key workloads. In all areas, manageability and performance have been
significantly improved.
Major new High Availability capabilities are also provided, including new flashback capabilities that reduce the
downtime caused by human errors. In addition, support for rolling upgrades has been supported to reduce the downtime
associated with database and application upgrades.
Security improvements in the first release focus on improved administration of large numbers of users across an
integrated end-to-end environment, and support for key security technologies.
Business Intelligence solutions will also benefit from the improvements in SQL Analytical, OLAP and Data Mining
capabilities. The ability to better support and more efficiently load and refresh larger databases is also improved.
Additional support for non-relational data stored in a database has also been improved in this release, with support for
new formats of multi-media data, addition of text classification capabilities, and improvements in search and retrieval
capabilities. XML capabilities have been also been expanded to focus on the effective management of large amounts of
XML data stored natively in the database. New location enabled services and spatial topologies are provided to better
support the key requirements of key Telematic and GIS partners.
Application Development improvements include support for a very performant and highly integrated XML capability
across the entire technology stack, and a database provided framework that allows desktop and middle tier applications
to retrieve and extract data from the database using standard Web Service mechanisms.
This new version also provides support for key requirements in the area of Bioinformatics.
PERFORMANCE AND SCALABILITY
The Oracle Database has a long history of providing the best performance and scalability on a large number of
architectures – from small to medium sized systems, to large scale SMP and clustered environments. This new version
of the Oracle Database continues this focus, with measurable performance improvements in all key workloads. Many of
these improvements are not the result of new features, but instead reflect the effort Oracle Development has made to
optimize and improve all areas of the current product offering. This approach provides the greatest advantage to both our installed base, and future customers – as they can more easily take advantage of these performance improvements
simply by upgrading or migrating to the newer version, without the need to modify or adapt their existing applications.
However, there are some key new capabilities in the areas of performance and scalability that should be highlighted.
Support For New Architectures
The first is the improved optimization of Oracle on Intel 64 bit platforms – benefiting those customers that deploy
Windows or Linux based solutions of this new architecture. Native support has been also provided for the Infiniband
network transport protocol, SDP, greatly improving performance and scalability in multi tier deployment architectures.
The new version also takes advantage of the Windows operating system’s support for Fibers.
High Speed Data Processing Capabilities
In this version a new type of table object has been introduced for classes of systems that require very high data
insertion and retrieval rates. This table structure better supports FIFO type data processing applications, where data is
quickly inserted and then later processed in the order it was inserted. Such applications are typically found in the Telco
and Manufacturing environments - for example, quick storage of CDR’s coming from a Telco switch which are then
picked up in the order they where inserted for processing by a Billing application. Applications that perform these types
of operations will see tremendous performance improvements by using this new type of optimized table structure.
Real Application Cluster Workload Management
This version of Real Application Clusters introduces a new service framework, that allows administrators to configure,
manage and monitor application workloads as a service, deployed across a number of nodes, in a large scale cluster
deployment. This workload management service framework is integrated with the existing availability extensions
provided in an earlier release of Oracle Real Application Clusters, allowing administrators to not only monitor and
manage performance levels for a given service, but also provide these services continuously.
Partitioning for OLTP
In this release, partitioning can increase the throughput of applications that perform a very high number of concurrent
inserts via support for hash partitioning of global indexes.
New Improved Scheduler
This release includes a new database scheduler, to provide enterprise-scheduling functionality. |
