What is Data Replication?A set of technologies that automates the cloning of application data – thousands and thousands of
tables at once
It also manages the capture, routing and delivery of transaction data in real-time
4
Continuous AvailabilityNo downtime during hardware or software upgrades
No downtime during application maintenance
Current Information for decision makingFresh data always available for reporting - Including Transactional Audit Data
Up-to-date information for critical business systems
Reduce and Control IT SpendChoose cost effective systems for analysis
Offload reporting to lower cost systemsMigrate applications from expensive systems
Business Drivers for Data ReplicationThe needs and pains

What the market is sayingCustomers and Analysts agree…
“Data replication is a flexible technology that can be used for many purposes, including data integration, data movement for data warehouses and ODS,
reporting server, migrations, and high-availability requirements. Transactional log-based replication is one of the most common usage scenarios”
Forrester TechRadar™ “Q1 2010 Enterprise Data Integration report “
At the CAB (Customer Advisory Board) meetings, the # 1 asked for enhancement to Informatica’s portfolio has been Data Replication
“Data Replication tools are the second most popular data integration tools types after ETL tools”
Gartner’s 6/6/08 report “Survey on Data Integration Practices Shows Move Toward Strategic Initiatives”

• Reduce downtime on any planned maintenance
• Lower costs • Mitigate risk by moving from
unsupported database version
This private financial firm had to upgrade the oracle systems and migrate to Linux to achieve currency on the versions without causing any disruptions to their
customers .
KEY BUSINESS IMPERATIVE AND IT INITIATIVE
INFORMATICA ADVANTAGE RESULTS/BENEFITS• Minimum disruption to first line
business applications• Keep the operational systems
up to date with latest versions of database software
• Reduce cost by migrating to Linux
• Ensure there is no overhead on the source system
THE CHALLENGE
• Ensure no system overhead on the source system by performing log based capture
• Effectively synchronize the source and target systems and continue to replicate the changes till the switchover
• Seamless transition from initial synchronization to real time change data capture
