ITCAM for RTT requires DB2 8.2 as a minimum. However, the install will continue and succeed if you have DB2 8.1 installed. The bad news is that ITCAM for RTT will NOT work.
I was using DB2 8.1 FP7 and thought it was close enough to 8.2, guess not. After install DB2 8.2 - everything worked OK.
Happy New Year
