Computerworld - From configuring and using Linux on mainframes to finding ways to use XML with older, critical business applications, the books reviewed below provide context, background and practical advice. If, like most IT managers, you're short on time and must be selective in your reading, we suggest that you take a look at these selections.

• Linux on the Mainframe, by John Eilert, Maria Eisenhaendler, Dorothea Matthaeus and Ingolf Salm, Prentice Hall, 2003, $49.99, 464 pages, softcover. Need a business argument for considering Linux on the mainframe inside your company? Then check out this book, which provides useful advice along with reasons to consider mixing Linux with IBM zSeries or S/390 mainframes. Written by four present or former IBM Lab employees, the book details benefits of running Linux on mainframes, including server virtualization, high reliability and excellent scalability. It also covers security, systems management, performance and capacity planning, and file-system selection. One of the best pieces of advice in this guidebook for both decision-makers and hands-on techies is to start with a small project to prove its ROI and then expand the deployment as needed.

Granor is also honest about listing areas where the software still has to catch up to Microsoft's king-of-the-hill suite, such as in the translation of heavily formatted documents.

If your existing business applications are still useful but lack new features such as XML, don't chuck them and start over. Instead, follow this how-to guide for adding XML capabilities by using file conversions and other means. Rawlins provides many examples of ways to integrate XML and non-XML applications so they can communicate to complete needed tasks without having to replace applications. Don't mistake this for an XML tutorial, however. Rather, the book is aimed at Java and C++ developers who already have a
