This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
CHeck out my signature links, and you'll find some development tutorials for WebSphere Portal that use IRAD. There are also some administration tutorials from an earlier version which might be helpful.
As far as books go, there aren't too many. I have one on development, but for administration, the few redbooks and what's on Amazon is about it.
