Use free software within commercial UNIX
Increase your productivity and take advantage of the free software that is currently available for the UNIX(R) platform. Tools like GCC (GNU gcc and gcc-c++ compilers), Emacs, and even core utilities like BASH and file utilities (ls, find, and so forth) started their life as free software alternatives under UNIX. In this article, you'll look at the development of some of these tools, as well as licensing, usability issues, and how best to install and integrate this free software into your commercial UNIX operating system.

Rexx and what it means for AIX
Nearly thirty years of growth haven't exhausted the the potential of the REstructured eXtended eXecutor (Rexx) language. The first of the widely used "scripting" languages continues to expand its capabilities and platform range, and it makes for a particularly good match with AIX(R).

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.

Use alternative methods to manage and monitor your UNIX servers
Make your systems and environment easier to use and administer by using tools, such as a Weblog, wiki, and Subversion, to record and track information and changes to your IT infrastructure. During the course of your UNIX(R) administration, you need to store and retain many different types of information and data. There are many ways of doing this, but one of the more radical solutions is to use a variety of free tools for the storage and retention of configuration data, configuration and administration change, and administration events.

System Administration Toolkit: Standardizing your UNIX command-line tools
Examine methods for standardizing your interface to simplify movements between different UNIX(R) systems. If you manage multiple UNIX systems, particularly in a heterogeneous environment, then the hardest task can be switching between the different environments and performing the different tasks while having to consider all of the differences between the systems. This article does not cover specific differences, but you'll look at ways that can provide compatible layers, or wrappers, to support a consistent environment.

Advanced Accounting Utilities for AIX, Part 1: Process accounting and LPAR accounting
Examine how the AIX Advanced Accounting facility in IBM eServer pSeries supports process accounting, logical partition (LPAR) accounting, and transaction accounting. IBM researcher Eric Wu describes the Advanced Accounting Utilities for AIX, which is available for download from IBM AlphaWorks. The Advanced Accounting Utilities for AIX includes two Web services and a Web application. One Web service is responsible for report generation and the other for facility management. The Web application acts as the client of the Web services and includes a Java servlet that handles Web requests. The Web application also includes JSP pages for presentation and human interaction.

Build UNIX software with Eclipse
Become more productive with your own code and others by utilizing Eclipse's syntax highlighting, code completion, and other amenities. Eclipse is an excellent open source IDE and has many helpful features. It runs on any UNIX(R) platform with a Java(TM) Runtime Environment (JRE) (Version 1.4 or newer) and an SWT port, such as Linux(R), Solaris, AIX(R), and HP-UX. It's easy enough to start a new project using Eclipse or to import an existing Eclipse project, but how do you bring existing code into the IDE? And what if you need to get an existing project compiling right away without modifying its existing makefile or configure script -- the most common ways of building UNIX software? Read along for the answer to all of these questions.

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.
