Can Oracle be a NoSQL player?

Oracle on Monday advertised the instantaneous accessibility of its new Oracle NoSQL database, but skilled population quizzed if Oracle will be a very large competitor in the complete NoSQL market.
The NoSQLmovement -- delineated substantially by its crosswise ascending and service of thoroughly trafficked websites -- is still quite nascent but has ensnared some mindshare in the database world, mostly with financial gatherings for instance Digg and Facebook employing it. Earlier this month, along with its statement about its Big Data Appliance due out in the first quarter next year, Oracle said that it would have a NoSQL database to depart along with a Hadoop record system. But as of now the Oracle NoSQL database is only obtainable on freestanding podiums for instance disseminated x86 servers.
Carl Olofson, examine vice head of request for paid job development and deployment at IDC in Framingham, Mass., said it’s hard to declare if Oracle will become a very large NoSQL player.

What is NoSQL (Not Only SQL)?

NoSQL database, in addition called Not Only SQL, is an advance to written knowledge organisation and database create that's practical for very large collections of disseminated data.

NoSQL, which includes in a large assortment of technologies and architectures, looks for to resolve the scalability and big data recital subjects that relationaldatabases weren’t created to address. NoSQL is principally practical when an enterprise wants to entry to and examine gigantic allotments of unstructured written knowledge or written knowledge that's preserved remotely on multiple virtual servers in the cloud. . 
produced by its label, NoSQL does not prohibit composed query terminology (SQL). While it's accurate that some NoSQL procedures are wholly non-relational, other people basically avert picked relational

Relational Database

A relational database is a accumulation of data details directed as a set of formally-described tables from which written knowledge can be accessed or reassembled in more divergent means without having to reorganize the database tables. The relational database was devised by E. F. Codd at IBM in 1970.
The yardstick customer and request for paid job program interface to a relational database is the structured query language (SQL). SQL assertions are employed both for interactive queries for knowledge from a relational database and for collecting written knowledge for reports.
In augmentation to being quite not hard to bring ahead and access, a relational database has the valued superiority of being not hard to extend. After the primary database creation, a new written knowledge group can be adjoined without demanding that all surviving requests for paid job be modified.

E. F. Codd (Edgar F. "Ted" Codd)

E. F. Codd (Edgar F. "Ted" Codd) formed the fundamental thoughts for directing and accessing data that are embodied in the relational database, the predominant advance to written knowledge governing body in today's enterprise world. Critical of IBM's then prevailing written knowledge organisation procedures, Codd, as a youthful IBM programmer toiling in IBM's San Jose Research Lab in California in 1970, recommended that written knowledge be directed as showed by beliefs supported on acknowledged family between assorted varieties of data. The written knowledge itself would be directed in two-dimensional (row and column) desks and precise details in a table

What is Oracle

Oracle (in aged Greece, a person in contact with the deities; from Latin, oraculum or divine announcement) declares it is the world's primary supplier of programs for knowledge organisation but it is best famous for its highly developed relational database yield (notably Oracle9i), which are employed in Fortune 1000 businesses and by more of the greatest Web sites. Oracle's relational database was the world's first to support the Structured Query Language (SQL), now an development standard.
When CEO Lawrence J. Ellison and a small number affiliates formed Oracle in 1977, they were out to confirm erroneous the existing model that relational databases could not be commercially viable. As validation of their triumph, they parlayed an first $2,000 financial endeavour in the financial gathering into an per annum profits surpassing $9.7 billion

Determining the present state engages both users and the mechanical architecture of the database.

How can I calculate Oracle database efficiency?

There are no trick recipes you can use to spit out the competence of a database. There are more metrics that can be employed to aid you ascertain if one environs of the database is playing well or not. I'd start with Statspack (Oracle 8i and 9i) or ADDM (Oracle 10g). You can get descriptions on more assorted characteristics of the database performance. For instance, you can observe if advancing your buffer cache will aid database performance.

LogMiner is an often dismissed yet very strong implement in the Oracle Database. It is employed to extract DML assertions from the redo log files—the primary SQL that produced the transaction and even the SQL that can change back the transactions.

Until now, this strong implement was ordinarily under-appreciated due to the deficiency of a more simple interface. In Oracle Database 11g, even so, Oracle Enterprise Manager has a graphical interface to extract transaction from the redo logs employing LogMiner,

Oracle Database 11g Release 2 (11.2.0.3.0) RAC On Oracle Linux 6.1 Using VirtualBox

Introduction

One of the large-scale obstacles stopping persons from setting up check RAC environments is the obligation for distributed storage. In a output natural environment, distributed storage is often supplied by a SAN or high-end NAS apparatus, but both of these choices are very costly when all you desire to manage is get some know-how establishing and utilising RAC. A lower alternate is to use a FireWire computer disk enclosure to permit two appliances to get access to the identical disk(s), but that still charges cash and needs two servers. A third choice is to use virtualization to phony the distributed storage.
Using VirtualBox you can run multiple Virtual Machines (VMs) on a lone server, permitting you to run both RAC nodes on a lone machine. In additon, it permits you to set up distributed virtual computer disks, overwhelming the obstacle of costly distributed storage.
Before you launch into this setting up, here are a couple of things to consider.
