COMPUTATIONAL GRID:
A network of geographically distributed resourcesincluding computers, peripherals, switches, instruments,and data.
What is a Grid an integrated advanced cyberinfrastructure that delivers:
Computing capacity
Data capacity
Communication capacity What is grid Computing -the process of interaction within
systems ,data and resource sharing with the help of thisgrid infrastructure .

A grid is a system that:
Coordinates resource sharing in a de-
centralized manner
Each user should have a single login accountto access all resources.
Resources may be owned by diverseorganizations.

set of individuals and/or institutions defined bya set of sharing rules
The sharing is highly controlled, with resourceproviders and consumers defining clearly andcarefully just what is shared

EASY JDBC INSTALL
This means your grid client doesnt need to installany Oracle software and yet you get easy secureaccess to data from an Oracle database running ona grid .
ULTRA LARGE DATABASE SUPPORTThis allows Oracle Database to utilize the ability of64-bit systems to create and manage ultra largefiles . The consequences of this is that OracleDatabase 10g can now scale up to 8 extra bytes insize 8 times the capacity of MS SQL SERVER 2000
and over 1000 times the capacity of IBM DB2 version8 .
DISTRIBUTED SQL AND DISTRIBUTED TRANSACTION
Oracle Distributed SQL allows grid users toefficiently access and integrate data stored in
multiple Oracle and non Oracle Databases.

User submits request through GUI
Application
Operating System and other requirements
Input data
Grid finds and allocates resources to
satisfy request
Grid notifies user when results areavailable

Use Resources Scattered Across the World Better access to data
Increased Collaboration across VirtualOrganizations (VO ) Groups of organizations that use the Grid to share
resources
we have the ability to distribute jobs to many smaller
server components using load sharing software thatdistributes the load evenly based on resourceavailability and policies.

Advantages
1.Grid environments are much more modular and don't havesingle points of failure. If one of the servers/desktops within
the grid fail there are plenty of other resources able to pick
the load. Jobs can automatically restart if a failure occurs.
