. This book is a summary and sublimation of practical experience. It is highly readable. It not only has in-depth research on exadata, but also shows them elegantly. It will lead readers to the exadata Hall. Go back to the top of the catalog to learn more about Oracle exadata The author introduces XXXI Technical Review

servers and Exadata storage deliver performance breakthroughs, ease of use and management, and deliver mission-critical availability and reliability. Because all Exadata database machines are configured in a consistent configuration, users can benefit from the experience of thousands of users who have deployed Exadata database machines for their mission-critic

With the development of enterprise business, there are more and more large data warehouses, and their scale is also expanding rapidly, increasing by three times every two years on average. Large Data Warehouses require scanning dozens, hundreds, or thousands of disks at the highest disk read speed, this requirement can be met only when the pipeline bandwidth between the disk and the server is increased by 10 times or more. Therefore, enterprises often find that the larger the data warehouse, the

said in the interview that the Exadata V2 database machine, the first hardware product jointly launched by Oracle and Sun, is now available to partners. In the previous advertisement, Oracle offered a reward to allow IBM to "Release the horse", and IBM chose to release its database

customers with a broad range of application services and platform services. Customers can also choose to run Oracle products in third-party public clouds. Many third-party SaaS ISVs and other public clouds are powered by Oracle technology. Finally, Oracle provides software that integrates across public and private clouds. For a private platform-as-a-service (P

In Exadata, it is best to run Exachk for health checks when there are any database-independent issues. Exachk collection of information is very complete, eliminating the tedious steps of manual collection. And after the collection is completed, you can make an assessment of the system's health status as a whole, including software, hardware, firmware version, configuration and other aspects of information, found some suspicious points, and then narrow

Exadata backup recovery is the same as that of a single machine or RAC database, but there are some optimization best practices for multiple nodes. Today, we will briefly talk about the backup and recovery of Exadata.To fully utilize the I/O capability and multi-node advantages of Exadata, we recommend that you allocate two channels on each DB node for testing. I

?? The benefits of Oracle's elastic Cloud and data warehousing are obvious, starting with the single vendor offering all the underlying components: Oracle's one-stop-all approach helps streamline licensing, support, upgrades, and consolidation, all handled by a single vendor. This may help prevent frequent vendors from blaming each other for technical problems. It is easier to configure, upgrade, and consolidate a single vendor approach, simplifying the contact and validation paths of these issu

The advantages offered by Oracle Resilient Cloud and data warehousing are obvious, first of all, that a single vendor provides all the underlying components: Oracle's one-stop approach helps simplify licensing, support, upgrades, and consolidation, all handled by a single vendor. This may help to prevent the frequent prevarication between vendors on technical issues. It is easier to configure, upgrade, and consolidate with a single vendor, simplifying

Label:Data Guard is a remote replication technology for Oracle, it has physical and logical points, but in general, it needs a separate system in a remote location, two sets of hardware configurations can be different systems, but the software structure of the two systems are consistent, including the software version, directory storage structure, and data synchronization (in fact, is not real-time synchronization), the two sets of systems as long as

Cost and performance of Oracle new-generation virtual computing All-in-One Machine To promote hardware sales, a new generation of integrated systems, including Oracle virtual computing All-in-One OVCA, and other integrated devices, were launched after Oracle's core dual-slot server market. At this point, Oracle first

The Data Guard is Oracle's remote replication technology, which has physical and logical points, but in general it needs to have a separate system in place, where two hardware configurations can be different, but the software structure of the two systems is consistent, including software versions, directory storage structures, As well as the data synchronization (in fact, is not real-time synchronization), the two systems as long as the network is available, is a remote disaster-tolerant solutio
