I am trying to understand what iowait statistics really mean (or signify) when the process is using aio. Theoretically, if running aio, you wouldn't have any iowait correct? This question has been raised because we are seeing significant iowait times even though our Sybase server is using aio...

We recently installed a new IBM 7040 Regatta. It has a Hardware Management Console that is a PC running Linux. We need to be able to establish a remote connection to this HMC in order to enable/disable processor configurations for testing. Has anyone been able to do this? I have contacted...

Has anyone had any experience interpreting the various TPROF reports? We are running Sybase and we have a job that appears to be CPU bound, but I suspect that other things are using the CPU besides 'real' work due to low I/O time. We are on an S80 with 18 CPU's and 16 gb of RAM and AIX...

Can someone explain to me how you control the order of name lookups with NIS, DNS, /etc/hosts? I've heard somewhere, I think, that this is done via /etc/netsvc.conf, but don't understand it in detail.

Does anyone know of a really good book (source) on the subject of performance tuning? I'm looking for something that does more than just 'point to the gauges', but actually digs down and explains how things work, what the options mean, and how to interpret performance files. Thanks, Steve

I just set up DNS in our test lab on one of our machines. I have it going up to our main machine for the company if it can't resolve a name on our local machine. Most everything is working fine, except that if I type in 'telnet orlprime', DNS doesn't recognize the machine. It just sits there...

On an S85 box with 8GB of memory, when we try to start Sybase, we get the following errors: 00:00000:00000:2002/05/08 10:37:17.74 kernel os_create_region: can't allocate 254234624 bytes 00:00000:00000:2002/05/08 10:37:17.74 kernel...

Our machines are located remotely, and we are functioning as a test lab, not production. We have been forced to use the service processor on site in order to reconfigure our processors (like disabling and reenabling them). It appears that there is a possibility that the 'diag' command allows...

First, I want to say that, as a beginner in AIX, I'm finding this site extremely helpful and my thanks to those who have responded to my questions. Here is another one... When you are installing software from bundles on the AIX CDs (like App-Dev, Server, Client, Media Defines, etc) do you have...

We are trying to install Oracle on our AIX box (4.3.3.8) and the installation errors saying that it can't find 'libsna.a'. It appears that this file is part of 'sna.rte', but I can't find this on the AIX CD's. Is this a separately licensed product or what? Thanks, Steve

I started out trying to find which 'bundle' /usr/samples/kernel is in (which I still can't find), and this led to other questions. How can you list files contained in software Bundles? How can you tell which Bundles are currently installed? Is there any way to have the installation actually...
