TOPIC: HugePages for Oracle databases

HugePages - what, why and how 

       

We live in the era of big servers with lots of relatively cheap resources like RAM and disk being thrown in with shovels. But most of the existing software is not ready out of the box to handle the growth that the servers are experiencing, hence come new issues to deal with.With huge amounts of memory in today's systems, properly handling this critical resource becomes paramount to avoid performance issues. This presentation will comment on the overhead of managing RAM and how this grows with the size of the memory chips. Most default operating system configurations still use small page sizes which makes having more RAM not a big advantage but, sometimes, a source of issues. We will go back to the basics of HugePages: what they are, why should we be using them and how do we take advantage of the feature. Aiming to have DBAs refreshing their knowledge of this feature and put it to work for them.We will also see some calculations on the impact of not using HugePages and some real-life situations where not having HugePages in place was the hidden root cause of some issues.
