ORACLE RAC QUESTION

                                  RAC               What   is   Cluster ? A cluster provides an optional method of storing table data. A cluster is made up of a group of tables that share the same data blocks. The tables are grouped together because they share common columns and are often used together          OR Two or more computers that share resources and work together to form a larger logical computing unit. RAC and Oracle Parallel Server can be used to access Oracle from multiple nodes of a clustered system. What is   oracle clusterware ? Oracle Clusterware is software that enables servers to operate together as if they are one server. Each server looks like any standalone server. However, each server has additional processes that communicate with each other so the separate servers appear as if they are one server to applications and end users. Why RAC, what are the benifits of using RAC? The benefits of Real Application Clusters: Ability to spread CPU

EXADATA ARCHITECTURE IN ORACLE

-
Image
OVERVIEW :                You can use Exadata to consolidate your storage environment Using Exadata multiple  databases can use storage from a single pool. Exadata uses Oracle Automatic Storage Management (ASM) to evenly distribute the storage load for every database across every available disk in the storage pool. Every database can use all the available disks to maximize performance. Exadata requires the use of Oracle Database 11g Release 2. Exadata works equally well with single-instance or Oracle Real Application Clusters (RAC) databases. Users and database administrators use the same tools and knowledge they are already familiar with. Being based on industry-standard components and technologies, Exadata is inexpensive to deploy. In addition, tight integration with the full suite of Oracle Database high-availability features, ensures that the reliability and integrity needs of mission-critical environments are met.              A key advantag
