Put all your eggs in one basket and --- WATCH THAT BASKET.
Following the IT industry's never-ending quest to introduce new and confusing names for well-understood concepts, our gurus in the High Availability engineering teams for the Oracle database and application server products have coined a new term: Oracle Maximum Availability Architecture.
From their OTN website
- "Oracle Maximum Availability Architecture (MAA) is Oracle's best practices blueprint based on proven Oracle high availability technologies and recommendations. The goal of MAA is to remove the complexity in designing the optimal high availability architecture."
This team held a fascinating session at OpenWorld 2006, "MAA Best Practices: Building an Oracle E-Business Suite Maximum Availability Architecture" (S283064). They covered a range of MAA topics for E-Business Suite environments, including:
- RAC, ASM
- Flashback databases
- Data Guard Redo Apply
- Disaster recovery
- Minimizing outages while converting to MAA architectures
- Switchover and failover procedures
- Hardware vendor partner validations on:
- HP-UX, HP 9000, HP Integrity, HP StorageWorks, HP ServiceGuard
- Sun Solaris, Sun Clusters, Sun Fire, Sun StorEdge
Excellent stuff. Associated with their OpenWorld session, they have a Powerpoint and a detailed whitepaper available for download. See the article below for pointers to the OOW Content Catalog.
