Cost of Downtime

Gartner’s estimate

• Average $42,000/hr

• Average 87 hrs per year.

Standish Group’s estimate:

• Mission-critical, $600,000/hr

• Large companies, $ millions

per minute.

Common Reasons for System Upgrade and Migration

Top Challenges for Major Migration Projects

Challenges Faced Result in Project DelaysWhich can decrease IT service levels

72% of UK Financial Services company believe data migration

to be “too risky”

More than 80% run over time and/or over budget

Cost overruns average 30%

Time overruns average 41%

•Target machine not available for use

• Must be like to like

• Distance constraints

• Failure cause or data corruption replicated as well

• Restart takes time when the database shuts down improperly

Oracle GoldenGate for Upgrades and Migrations

Zero Downtime ….

Oracle GoldenGate: Zero Downtime Database Upgrades

Minimize Risks with Failback

• Upgrade from priorreleases to Oracle

Database 11gRelease 2

• Verify data consistency

• Minimize risks with failback option and phased migration

Real-time changed data

Oracle GoldenGate Query OffloadingImprove Production System Performance and Lower Costs

• Off-load queries from production systems in:

• Heterogeneousconfigurations

• E.g. legacysystem queryoff-load

• E.g. differentOS, databaseversion

• Enable continuous

availability during

unplanned and

planned outages

• Synchronize data

Agenda

• Summary

• Q&A

Oracle Solutions

• Migrated from HP NonStop and MySQL to Oracle without downtime

• Upgraded to Oracle Database 11g without downtime

• Offloading ―looker‖ queries to a set of replicas for performance improvements

• Real-time data feeds to DW

Return on Investment

Decreased TCO by 80% with offloading “looker” activity to lower cost replicas

Lowered software license costs by 64% and hardware costs by 88% by moving from HP NonStop to Oracle Linux

Reduced software maintenance by 69%, hardware costs 81% and hosting costs by 79% moving from MySQL to Oracle

Business Challenges

• Handle growth and scale, while reducing TCO via platform changes

• Ensure continuous availability of Air Travel Shopping Engine (ATSE)

Customer Example: Sabre Holdings

Solution

• Multi-master data replication with Oracle GoldenGate across 5 data centers in 3 continents for data distribution and availability

• Zero downtime migration from single to a 2-node RAC with ASM across OS

• Consolidated real-time reporting on Oracle Exadata to remove performance impact on source systems

Support 24/7/365 global manufacturing operations and meet customer SLAs

Upgraded its systems for enhanced scalability without impacting business

Improved system performance by offloading real-time reporting to Exadata

Business Challenges

• Need 24x7 uptime to support global operations and strict SLAs

• Very small monthly window to take downtime for upgrades, migrations, and planned maintenance

• Each plant’s data center needs to have up-to-date data on each device for multi-step production process

Customer Example: Research In Motion- BlackBerry

Solution

• Deployed Oracle GoldenGate for multi-master, 4-way replication with Oracle and MS SQL Server 2005 databases supporting fraud detection and payment processing systems

• Replaced home-grown legacy replication

• Enables geographic distribution

• Allows for reporting against DSS systems

• Time to recover: ZERO minutes

• Reduced total cost of ownership by using lower cost hardware

• Meets SLAs on availability and performance

• Single HA solution for all database platforms

Business Challenges• High cost of downtime - if payment processing or fraud

detection systems are not working, ReD’s clients lose millions of dollars per hour.

• Service Level Agreements dictate 99.95% availability with aggressive sub-second average response times.

• Must ensure quick, massive scalability
