Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

We have RHEL linux and run Oracle 11GR2 2 node RAC. since we have huge SGA's and since the system was showing heavy paging activity as reported by sar -B, we enabled Hugepages on the system.
Below are the system details :
1) The pgpout/s values as shown by sar -B.. Are these normal? The system is not loaded in anyways.
2) Oralce and sys admins say they do not find any issues but my Oracle OEM says that huge paging activity at the system level.
Could you give insights to the pgpout/s values what it means and what are some acceptable values ?
