No, I don't know which tables they were from since I'm not that familiar with the application data. I could probably track it down if I needed too, although it might be impossible to tell for sure since some of the data, e.g. order numbers, probably exists in multiple tables. I don't see the point in checking the rowid and source datafile though - I know that the data is from somewhere else and is now showing up in my brand new datafile that I just created.
I'm not very familiar with block dumps and not sure if Oracle will dump blocks that it considers to be empty/unused since they aren't part of any segment yet - do you know if it will and if so, how do I do it? I'm still not sure what this would tell me either. There is no doubt that Oracle is putting data into this datafile where it doesn't belong so I don't need to verify that anymore - all I want to know is if this is normal behavior and why it does this. It's not really causing me any problems since I don't have any encryption requirements and my server is secured so nobody can go grepping through my datafiles anyway - I'm just curious.
