Presentation Title: The Answer to Free Memory, Swap, Oracle and Everything

Presentation abstract: Do I have enough memory? Why is my free memory so low? Am I swapping to disk? Can I increase my SGA (db cache) size? Can I add another instance to this server? Are my system resources used optimally? These are all questions that often haunt DBAs. This presentation is The Answer. It covers in detail the different types of memory, how to monitor memory and how to optimally use it with Oracle in mind. Multiple examples throughout the presentation demonstrate how certain actions on the database side cause different memory areas to be allocated and used on the OS side. Key underlying differences in operating systems approaches to managing memory will be highlighted with special attention given to Linux, Solaris and Windows. Using Linux as an example throughout, this presentation explains how to effectively use tools such as “top”, “vmstat” and “/proc/meminfo” to gain visibility into a system’s allocation and use of memory.
