BKJIA exclusive Article] Oracle's revenue in the third quarter has increased slightly, and the integration of Sun is progressing smoothly. Exadata database machines are in progress, and SAP has divested poor product lines. All bottom and top lines exceed Wall Street's expectations, all of which show that Oracle runs well. With such a good momentum, we have been talking about how

1.1 Oracle Cloud Computing Introduction
As cloud infrastructure matures, more and more companies are beginning to focus on the implementation of cloud computing, accelerating the deployment of cloud computing solutions, and migrating their IT applications and data resources to cloud environments. For the "cloud" of potential users, they are most concerned about how the "cloud"
BKJIA San Francisco site report] at the 2009 Oracle Global Conference OpenWorld, OOW, everyone is not new to Oracle new database machine Exadata V2 challenge IBM database machine pureScale. However, the current understanding of the Exadata V2 database machine in the industry remains in many concepts. For enterprise use
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
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.

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

In the previous article, we will build a DB node. The establishment of a DB node is no different from that of a common RAC node. Note the following two points:

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 machine pureScale one day before OOW 2009, known as the "
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. In addition, to allow all DB nodes to particip

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
Factors to consider before upgrading to Oracle DB 12c: The function of the EM Express 12c in DB 12c is reducedIf you use notifications in DB control, perform a task, and so on, and there is no such function in EM Express 12c, you need to consider these issues extra. The reco
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

At the same time, Oracle recently released a series of cloud-oriented Database and software integration products, including Oracle Database 12c)

What we now know about the software industry is actually after the decoupling of hardware and software, the US enforcing anti-trust legislation for proprietary software and hardware vendors. Hana, as an application and database coupling, is controlled by a single vendor, which brings us back to the earliest days of software.PS. Oracle's Exadata is also a combinati
