It tells us that you forgot to post the next ten lines of your
tops output, and that you failed to give any detail about the
machines physical details, e.g. HDD subsystem, network cards, ...
And the disk-subsystem on the machine is ... ?
Who or what is it talking to in terms of networking, are you
running an (or several) app-servers against it?
More than one network card? What speeds?
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? :}
Sorry, I didn't mean to ignore your question, I just don't understand what you mean since I am very sufficient with Linux.
And the disk-subsystem is?
how do you find out about this
And what Oracle version are you running?
Oracle 10G release 2
How do the users connect, running plain old sqlplus against it?
I don't know at this points. At this point, I am still looking for who/which datababse drag the system down
If you don't ming to let me know how to narrow down and troubleshoot the problem, that would be greatly appreciated. Like right now is off business hours and the iostat still hight.

If you're the sys-admin you should know off the top of your head :}
Have a look at the output of
fdisk -l
and we'll (try to) tackle it from there.

15 DBs on a machine with only 4GB RAM?
Hope they're not too big/busy.
What kind of app is Oracle being used for? Have you configured
opmn and emctl for those databases?

How can you if you don't know what's happening?

Chances are that the machine is busy paging stuff in and out.
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
