Oracle Maximum Availability Architecture (MAA) is Oracle Corporation’s HA best practices blueprint based on Oracle high availability technologies such as Real Application Cluster, ASM, Data Guard, Exadata, Flashback technologies, etc. The goal of MAA is to design the best high availability architecture with the greatest return on investment and quality of service
Downtime is something every mission critical business wants to avoid or minimize, whether it is due to planned or unplanned outages. Oracle offers a number of features and proven operational and configuration practices to minimize downtime.
This session aims to demystify the HA features offered by Oracle and outline a clear set of best practices to avoid and minimize downtime for all outages. I will provide real world examples of how MAA best practices have prevented prolonged downtime when faulty HBAs corrupted the primary database, how a leading telecom reduced downtime exposure from two hours to its minutes for outages resulting in site failover, and how legal and insurance firms reduced downtime to minutes using Data Guard switchover for upgrades and major system changes. I will also describe how to configure for zero downtime for most unplanned and some planned outages.
