1. Exadata 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 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

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

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

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

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 "

[Oracle] Exadata virtual machine configuration (2 ). 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: 1. Create related directories and add two files [Oracle @ DB ~] # Vi/etc/oracle/cell/network-config/cell

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

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

directly read the SGA, then some of these problems can be solved in minutes, is not very cool?4. Application Performance TraceabilityThere are some problems that are obviously applied, but if you don't tell him exactly which application module it is and which user is doing it, you can hardly say that it is an application problem.If the OPS management tool can not only help you find out which SQL statement is causing the program, but also tell you which path is crawling from, which jar package o

some time ago, I saw MacLean Liu share a good article on Exadata I/O performance calibration: Calibrate Test Exadata IO, this article basically covers the exadata I/O performance calibration method. Just recently someone has asked me this question, so I will try to make some additions to the fish, there is duplication of places please ignore it. If I/O performa

OSwatcher is a script tool recommended by Oracle for OS-level running status detection. Exadata is installed by default. But how does Exadata automatically start OSwatcher after the system starts? How can we modify OSwatcher parameters to adjust monitoring and log storage policies? This article describes how to modify OSwatcher parameters from system startup to O

Data warehouse all-in-one What is all-in-one machine? Applicance does not have a general definition. It should have the following features. It should be a device specially designed for a specific application field. It is centrally optimized for

The most useful feature of exadata-storage Indexes Unknown storage indexes are the most useful functions in exadata. They are not traditional indexes stored in databases like Oracle B-tree indexes or Bitmap indexes. In fact, in the traditional sense, it is not even an index. We cannot use storage indexes to locate a series of records with specific values on a giv

Exadata introduces the concepts of lun, celldisk, and griddisk in the disk section. Here we will briefly introduce them. For example, after a physical hard disk is added to the Cell, the LUN will be automatically created, LUN Exadata introduces the concepts of lun, celldisk, and griddisk in the disk section. Here we will briefly introduce them. For example, after a physical hard disk is added to the Cell, t
