Typical Challenges with Disaster Recovery (DR) Deployment

Risk(*)

• Data inconsistency or corruption

• Business exposure to lost critical transactions

• Company reputation at stake

Cost

• High investment in Hardware and Software

• DR site operational aspects

• Lack of clear ROI (unless a disaster occurs)

Complexity

• Planning & Deployment of the DR site

• Primary / DR synchronisation

• On-Demand elasticity after migration to the DR site

(*) Q: How many of your customers follow regular CA procedures?

The World’s Largest OLTP System

http://www.oracle.com/technetwork/database/availability/11256-exadata-oltp-paypal-1864630.pdf


Largest OLTP database

• Fast paced VLDB OLTP environment on Oracle

– 500+ database instances

– OLTP databases commonly 10-130 TB

– 5,000-14,000 concurrent processes; 120,000 executions/second, 25MB Redo/Sec

• Continuously growing

– Database size double every 18 months

– Workload double every 3 years

• Stringent uptime requirements– We are a financial company that operates at Internet scale

– Need high performance, scalability, and consistency

• We rely on MAA for our high availability architecture– 200+ Active Data Guard deployed

– 50+ RAC databases; 50+ GoldenGate instances

• Oracle MAA is standard for HA/DR

• 1000’s of Oracle Database instances

– Seven application tiers (Tier 0 through 6)

• Tier 0 has RPO/RTO of Zero

– Oracle RAC, ASM

– Active Data Guard

– GoldenGate

• Automatic restart of GoldenGate replication after a database outage
