|Optimizing AIX 5L
performance: Tuning network performance, Part 2
This three-part series on AIX (R) networking focuses on the challenges of optimizing network performance. Part 1provided a networking overview and also discussed the tools you need to monitor your hardware, including netstat, netpmon, entstat, and nmon. Part 2 focuses on tuning NFS. You'll learn about monitoring utilities such as nfsstat and nmon, and you'll also tune with nfso. The series also offers best practices for network I/O performance tuning.

|System Administration Toolkit: Monitoring disk space and usage
Look at methods for determining disk usage across multiple UNIX(R) systems and how to create a simple warning system to alert you of potential problems. Keeping an eye on your file systems and ensuring they don't fill up is a trivial, but vital, process in the day-to-day management of your UNIX systems. In this article, you'll look at methods for keeping an eye on disk space, discovering which files, users, or applications are using up the most space, and how to make use of quotas and other solutions to find the information you need.

|nmon performance: A free tool to analyze AIX and Linux performance
This free tool gives you a huge amount of information all on one screen. Even though IBM doesn't officially support the tool and you must use it at your own risk, you can get a wealth of performance statistics. Why use five or six tools when one free tool can give you everything you need?

|Transition from Solaris to AIX
So you've been the UNIX(R) guru on your team for years now and senior management has determined, without your input, to migrate to IBM from Sun Microsystems. Other than updating your resume, what do you need to do? Can you make the transition to AIX(R)? What does IBM offer as an alternative to either VERITAS or Solaris Volume Manager (SVM)? In this article, use the filesystem management and tools available to you on AIX to make your transition easier.

|Techniques for memory debugging
Exercise good memory-related coding practices by creating a comprehensive program to keep memory errors under control. Memory errors are the bane of C and C++ programming: they're common, awareness of their importance for over two decades hasn't eradicated them, they can impact applications severely, and few development teams have a definite plan for their management. The good news, though, is that they needn't be so mysterious.
