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.

I don't have any app running on this server, I just have 15 databases running and couple users are connecting to them concurrently, this machine is fairly new with dual Xeon processor, the IOWAIT are at peak almost al the time so I am trying to find out what is happening.
And the disk-subsystem is?
And what Oracle version are you running?
How do the users connect, running plain old sqlplus against it?
And why do you always only ever answer one of my questions
ignoring the rest?
How am I supposed to help when you don't answer the others? :}
thanks so much for your advises and now I found out I don't have fdisk functionality neither iostat on my server so the next question is what package do I need to install so I can those two utilities loaded on my server.
Could you please put code-tags around the stuff you copy & paste
to make it more readable? Zip should be fine, other compression
methods would a) use more CPU or b) be inefficient at compression,
there's just a lot of I/O going on.
Can you give me details about the hardware we're looking at?
Server type, CPU speed, controller type ... and again: if the
box is a RedHat machine make sure you have turned auditing off,
otherwise it will be happily playing with itself. The auditing
is something you may want on a file-server, but definitely NOT
on a database machine.
And once again: it would be nice if you provided more detail
in the first place, e.g which distro and version you're using ;)
For future reference, and to make both your and our lives with
helping you easier, read this, please
