Objectives:	Understand how to monitor Oracle RAC on Linux. Learn how to tune Linux for Oracle RAC. Understand how to approach troubleshooting RAC on Linux.
Abstract:	This session will discuss how to tune and troubleshoot an Oracle Real Application Cluster implementation on Linux. Potential problems and pitfalls will be identified as well as time proven solutions. This discussion will include the latest in RAC hardware technologies, as well as monitoring and tuning RAC on the Linux operating system. The rush to implement systems on Linux has left some implementations with performance problems. Customers that have previously used Oracle on other UNIX platforms are less familiar with the performance monitoring tools that are available on Linux. These tools include sar, vmstat, iostat, and sar. This paper will cover Linux specific problems such as the difference between 32-bit and 64-bit Linux, low and high memory and the Linux kernel architecture. It will include how to identify I/O bottlenecks, and monitoring Linux memory. The speaker’s company has deployed more than 150 RAC clusters on Linux.
