• A database is an organized collection of data.

• Databases are created to operate large quantities of information by inputting, storing, retrieving, and managing that information.

• Databases are set up so that one set of software programs provides all users with access to all the data.

• A Database Management System (DBMS) is a suite of computer software providing the interface between users and a database or databases.

• Database management systems (DBMSs) are specially designed applications that interact with the user, other applications, and the database itself to capture and analyze data.

• Oracle is an American multinational computer technology corporation headquartered in Redwood City, California, United States.

• Founded by Larry Ellison, Bob Miner, Ed Oates in the year 1977.

• The company specializes in developing and marketing computer hardware systems and enterprise software products – particularly its own brands of database management systems.

• Oracle is the third-largest software maker by revenue, after Microsoft and IBM.

• The company also builds tools for database development and systems of middle-tier software, enterprise resource planning software (ERP), customer relationship management software (CRM) and supply chain management (SCM) software.

• The Oracle Database (commonly referred to as Oracle RDBMS or simply as Oracle) is an object-relational database management system produced and marketed by Oracle Corporation.

• Oracle 11g was released in 2007 and introduced many new features enabling database administrators and developers to adapt quickly to changing business requirements by simplifying the infrastructure and using automating tasks wherever possible.

• Two versions:oStandard edition: Available on single serveroEnterprise edition: Available on clustered server with

no socket limitation

Database Replay

• Capture Workload in Production• Capture production workload with actual load & concurrency• Move the captured workload to test system

• Replay Workload in Test• Make the desired changes in test system• Replay workload with production load & concurrency

• Analyze & Report• Errors• Data divergence • Performance divergence

SQL Performance Analyzer

• Enables to assess the performance impact of any system change resulting in changes to SQL execution plans and performance characteristics

• Examples of common system changes for which you can use SQL Performance Analyzer

Database upgrade Configuration changes to the operating system, hardware, or

database Database initialization parameter changes Schema changes

Flashback Data Archive

• Flashback data archive consists of multiple table spaces and stores historic data from all transactions.

• Retains historical data for the time duration specified using the RETENTION parameter

PREREQUISITE:• Must have FLASHBACK ARCHIVE ADMINISTER and

CREATE TABLESPACAE system privilege• Must be logged in as SYSDBA

MANAGEABILITY IN 11g

• More database administration automation

• More intelligent advisors to simplify administration

CASE STUDY

BRITISH TELECOMMUNICATIONS

HISTORY

• British telecommunications is one of the world’s leading telecommunications companies.

• BT has almost 93,000 employees serving customers in more than 170 countries worldwide.

• In UK, the company provides broadband products and service to almost six million customers, as well as fixed-line, mobile and TV offerings to millions more consumers.

• Worldwide, BT sells wholesale products and services to leading communications providers and supplies managed network services to a wide range of corporations and government organizations.

• BT Operate is the internal service unit responsible for managing BT’s IT and network infrastructure platforms, as well as delivery and problem resolution for all products and services sold to BT customers worldwide, retail and wholesale.

• Its staff includes over 13,000 IT professionals in more than 20 countries.

PROBLEMS

• BT had a large and growing database infrastructure that Surren Partabh, CTO Core Technologies of BT Operate characterized as “rapidly falling into legacy due to the pace of technology innovation we see in the world.”

• Company’s large range of products and services inevitably led to a sprawling set of application and operational silos dependent on thousands of databases.

• Keeping up with upgrades and patches was an enormous job.

• Day-to-day management was difficult.

• Difficult to keep up with customer expectations and competitive demands.

• Application deployment was slow and expensive.

• Ever-growing complexity of the company’s database infrastructure was raising operational costs and staffing requirements, with IT workload soaring.

• Company had DBA’s begging to retire, but company couldn’t afford to let them go.

SOLUTION:Database Consolidation onto a Private Cloud with Oracle Database 11g

• The company decided to build a DaaS platform using the features and options of Oracle Database 11g to create a private cloud.

• Oracle Real Application Clusters enabled BT to standardize their deployment model, reducing the deployment time for a fully-tested, highly available database from two to three weeks down to only 19 minutes.

• Other Oracle database 11g features and options such as Clusterware, Automatic Storage Management(ASM), Advanced Compression and Partitioning also played an important role in BT’s private cloud consolidation

• BT moved the applications on legacy systems over to the Oracle Database 11g private cloud.

RESULTS

• Consolidation onto a standard Oracle Database 11g cloud has made management so much easier that they are managing 30% more databases with 20% fewer personnel hours.

• It improved business agility.• Improved customer service.• Reduced cost.

• This is Oracle Enterprise Edition introduced in the mid of 2013.

• It provides the industry's only complete, integrated, and business-driven enterprise cloud management solution.

DATABASE MANAGEMENT FEATURES

• Database creation and up gradation via Cloud Control

• Database Cloning , Useful when migrating database from development to test

• Backup and Restore Enhancements, Backup can be performed Sequentially in one deployment procedure

• Active Report Function, Data can be saved in HTML file and used for offline analysis

MIDDLEWARE MANAGEMENT FEATURES

• Topology views enables visualization in a Graphical display

• Performance summary baseline support, for comparing baseline performance data against current performance data

• Configuration search enhancements, useful in creating user defined search

PERFORMANCE MANAGEMENT FEATURES

• Diagnose problems 3 to 5 times faster than the other than the other Application Performance management solutions

• Reduce downtime by as much as 73 percent• Increase online revenue by around 23 percent.

Dena Bank

Dena bank

Dena Bank

Solution• Engaged Oracle Advanced Customer Support

Services, Oracle Consulting, and Oracle Partner HCL Infosystems to help improve customer service and support future growth

• Enhanced customer service by increasing the speed of ATM transactions by 80% and reduced the number of declined transactions from 10% to less than 1%

• Provided a huge database and storage infrastructure

Dena Bank

• Supported ATM transaction and customer growth—and enhanced system

• Decreased the total cost of ownership• Ensured core banking and ATM applications are

always available by providing automatic failover capabilities, which shift processing load from one server to another in the event of a system failure

• Stored database and application data more effectively and at the lowest possible cost by deploying a scalable storage area network

Conclusion

• Migration Preparation is Essential

• Pick the Right Migration Method.

• Fast Network Reduces Migration Time

ORACLE DATABASES: CONCLUSION

• Oracle databases are all about robustness, power and exceptional data maintaining capabilities.

• Security and performance are the highlight of Oracle databases.

• However, Oracle databases are feasible only when you need large databases. With the amount of work and hardware needed to deploy, it is not ideal for small or mid-sized companies where other feasible options such as MySQL or Microsoft SQL can be more cost effective with similar functionality.

• Oracle databases are notorious for their complexity and therefore not the ideal choice when either the workforce isn’t highly technical or you want an easy-to-use database with basic features.
