Businesses today operate in a highly networked, 24x7 global economy. They cannot afford to be down, and the IT systems supporting today's businesses have to be always available. This is where MAA comes in. The Maximum Availability Architecture provides superior data protection and availability by minimizing or eliminating planned and unplanned downtime at all technology stack layers including hardware and software components. This presentation will introduce the Oracle and IBM technologies we use to achieve MAA and the best practices from the Oracle/IBM Joint Solutions Center of Montpellier and recommendations on how to design, implement and manage an optimum high availability architecture on an Oracle E-Business Suite R12 on IBM Power running AIX context. The goal of MAA is to remove the complexity in designing the optimal high availability architecture for a critical system.
