When you install ContentServer on DB2, there is an important step in the installation manual that can be easily overlooked. When you create a database, you have to select pages to be 32k. The default is 4, and also the image in the installation manual shows 4k, so you can easily forget it. If you don't set pages to 32k, installation will misteriously fail... And this is a problem that can be very hard to track.
