Optimizing AIX 5L performance: Tuning disk performance, Part 1
Learn more about direct I/O, concurrent I/O, asynchronous I/O, and best practices for each method of I/O implementation. This three-part series on the AIX(R) disk and I/O subsystem focuses on the challenges of optimizing disk I/O performance. While disk tuning is arguably less exciting than CPU or memory tuning, it is a crucial component in optimizing server performance. In fact, partly because disk I/O is your weakest subsystem link, you can do more to improve disk I/O performance than on any other subsystem. 		Articles 10 Jul 2007  
 
Optimizing AIX 5L performance: Tuning disk performance, Part 3
Part 3 of this series covers how to improve overall file system performance, how to tune your systems with the ioo command, and how to use the filemon and fileplace utilities. 		Articles 09 Oct 2007  
 
Optimizing AIX 5L performance: Tuning disk performance, Part 2
Discover how to use appropriate disk placement prior to creating your logical volumes to improve disk performance. Part 2 of this series focuses on monitoring your logical volumes and the commands and utilities (iostat, lvmstat, lslv, lspv, lsvg) used to analyze results. 		Articles 24 Jul 2007  
 
Optimizing AIX 6.1 performance tuning
Just when you thought you understood performance tuning on AIX(R) Version 5.3, here comes AIX 6.1 on its heels to throw you a curveball. In this article, get up-to-date information on the recent changes to performance monitoring and tuning in AIX 6.1, including CPU, virtual memory, and I/O (disk and network). Many of the changes are really less about kernel innovations and more about ancillary changes, such as improving default parameters to more accurately reflect real-world data processing. Other enhancements include unique tunable documentation, restricted tunables, and various other improvements to certain subsystems. You'll learn more about a performance tuning methodology, which needs to be a part of any tuning strategy. 		Articles 05 Feb 2008  
 
Running Oracle on AIX
A systems administrator always needs to be cognizant of system performance. This article drills down into the many aspects of tuning AIX to run Oracle. We'll look at the Virtual Memory Manager (VMM), CPU, Memory and I/O (disk and network). We'll examine some of the tools that you can use to analyze bottlenecks, while also making some changes to the system. Finally, we'll also review some Oracle tools you can use to help with your performance tuning. 		Articles 24 Jun 2008
