Recommended Reading: Oracle Database 12c NUMA-Related Topics

Published January 7, 2015 oracle Leave a Comment

This is a short post to recommend some recent blog posts by Nikolay Manchev and Bertrand Drouvot on the topic of Oracle Database 12c NUMA awareness.

Nikolay provides a very helpful overview on Linux Control Groups and how they are leveraged by Oracle Database 12c. Bertrand Drouvot carried the topic a bit further by leveraging SLOB to assess the impact of NUMA remote memory on a cached Oracle Database workload. Yes, SLOB is very useful for more than physical I/O! Good job, Bertrand!

These are good studies and good posts!

Also, one can refer to MOS 1585184.1 for more information on Control Groups and a helpful script to configure CGROUPS.

The following links will take you to Nikolay and Bertrand’s writings on the topic:
