You are very welcome. I wish you success. BTW I had gone through these exams by reading only Prep Series by IBM. I may find a book for you.
Other than that you may have a look at sarbjitsinghgill.com/Tutorials. These are not for exam; but these allow you to be comfortable with installations and basic tasks.
I will be happy to help you if you call me for help.
One note. : DB2 is very most compatible to IBM PC compatibles; however if you see an issue bringing you down; please use VirtualBox to get it going. On my PC I have 6 different VirtualBox machines that help me switch quickly between platforms and softwares.
