3 3 Oracle High Availability Architecture 1.Scale-Out & Low-Cost – High-volume hardware – All components active 2.Application Oriented – Protect and recover application objects – Enable online application changes 3.Integrated & Simple – Availability integrated into all components – Automated 4.Complete & Open – Handles all planned and unplanned downtime – Pluggable components

4 4 Oracles Database HA Server Failures Data Failures System Changes App Changes Unplanned Downtime Planned Downtime Data Changes

5 5 Server Failures Data Failures System Changes App Changes Unplanned Downtime Planned Downtime Real Application Clusters (RAC) Best-of-Breed Server Protection At Lowest Cost Data Changes

6 6 Scale workloads across multiple low cost servers Consolidate into fewer servers and databases Runs all Oracle database applications Built-in HA HRSALESERP Real Application Clusters

7 7 A virtualized single instance database – Omotion - live migration of instances across servers Move services, then shutdown transactional – Built-in cluster failover for high availability Better than OS level virtualization – Rolling database patches – Manage fewer Operating Systems 10 DBs on a node does not mean 10 Operating Systems to manage – Rolling OS upgrades New in 11.2 RAC One Node Virtualization Benefits for Oracle Databases

8 8 Data Corruptions Storage Failures Site Failures Human Errors Server Failures Data Failures System Changes App Changes Unplanned Downtime Planned Downtime Data Changes Best-of-Breed Data Failure Protection At Lowest Cost Flashback RMAN Oracle Secure Backup ASM Data Guard Streams

9 9 Flashback revolutionizes error recovery – View good data as of a past point-in-time – Simply rewind data changes – Time to correct error equals time to make error Correction Time = Error Time + f(DB_SIZE) Low impact, easy – simple commands, no complex procedure Flashback Query, Table, Transaction, Database, Drop SQL> flashback database to ; Enhancements in 11.2: Flashback database performance & monitoring optimizations Flashback archive support for schema evolution Recovery Time Traditional Recovery Flashback Flashback Technologies Error Detection & Correction New in 11.2
