It’s always very hard to find good documentation on some products (IBM or else). Internet is really nice, but sometime it’s the jungle, we can find lot of good, but also lot of bad/false.. Shop sells very good books, but come on.. they’re too expensive, I’m student, I can’t buy 10 or 20 books near 50/60€ each..

Hopefully, IBM have a huge ebook library named Redbooks. There are 5 kinds of IBM ebook, first is the classic RedBook, it’s a guide on one or multiple producs, Drat are RedBook in beta version, RedPapers are short technical articles, RedGuides are a kind of praticals business example, and TechNotes are brief technical help on something very precise.

IBM have more than 5.000 RedBooks, in 2008 more than 400 Redbooks have been published. Each month, more than 500.000 ebooks and 100.000 RedPapers are downloaded.

Here are some “must have” Redbooks:

• Up and Running with DB2 on Linux
• VSAM Demystified
• DB2 9 for z/OS Technical Overview
• ABCs of z/OS System Programming Volume 1 (on 11)
• DB2 9 for z/OS Performance Topics

And, the most important, all these ebooks are free !
