Biographical Sketch: An Oracle ACE with a deep understanding of databases, application memory, and input/output interactions, Christo Kutrovsky is an expert at optimizing the performance of the most complex infrastructures. Methodical and efficiency-oriented, he equates the role of a Pythian Consulting Group consultant in many ways with that of a data analyst: both require a rigorous sifting-through of information to identify solutions to often large and complex problems. A dynamic speaker, Christo has delivered presentations at the Independent Oracle Users Group, the UK Oracle User Group (UKOUG), the Rocky Mountain Oracle Users Group, Oracle Open World and other industry conferences.
Title: The Answer to Free Memory Swap Oracle and Everything
Summary: 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. Multiple examples in 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 look into into a system’s allocation and use of memory.
