UNIX Performance Management – The purpose of this paper is to introduce the performance analyst to some of the free tools available to monitor and manage performance on UNIX systems, and to provide a guideline on how to diagnose and fix performance problems in that environment. The paper is based on the author’s experiences with AIX and will cover many of the tools available on that and other UNIX platforms. It will also provide some Rules of Thumb for analyzing the performance of UNIX systems. The paper has been updated to include some of the things that can be done in order to make sure that the web server will perform well.

You can also keep your builds consistent if you have one mksysb image to build an AIX server. This also makes server builds easier at remote locations, no more swapping CD’s[...]
AixErrorLogCustomization < AIS < TWiki – AIX has a very flexible error logging daemon to log hardware and software errors. The log is typically accessed with the errpt command. Unfortunately, checking the log is a manual process. Using some custom ODM entries, we can cause AIX to run commands in response to errors, which can then be used for notification. Below I document a simple configuration which uses the ODM to log each error entry to syslog, and forward the complete entry via email.
c99madshell Security Review – Derek Fountain – A friend of mine got hacked recently. Some charming person managed to upload a rogue file to his server and replaced some of the software executables he produces with versions containing trojans and viruses.
