Oracle Deployment on x86-64 Linux: Best Practices for Oracle On Demand

Today, Oracle On Demand uses x86-based servers running 32-bit Linux OS in its data center. These servers offer excellent value and performance. However, in order to address limitations in 32-bit architecture that may affect performance, scalability, and reliability in some cases, Oracle On Demand is now deploying 64-bit infrastructure to complement the existing 32-bit environment. This white paper describes some of the limitations faced by 32-bit servers and how AMD Opteron-based x86-64 servers running 64-bit Linux OS are being used to address them for the On Demand environment. This paper includes best practices from the 64-bit deployment within the Oracle On Demand data center.
