In trying to figure out this problem (which is still unsolved and I still have no clue what is going on), I am wondering if maybe an external reference to the table in question is causing the problem. For example, a trigger or view or some other such thing.
Is there an easy way to find all references to a given database table? Including all views, triggers, constraints, or anything at all, preferably from the command line, and also preferably without a 3rd party tool (we are using db2).

Can Unix shell script be used to manipulate databases?
Good ole DB2..
Do you know any good distributed database systems?
I find the publib db2 docs view very very handy by the way:.
When is it time to change database backends?
How important is a database in managing information?
I just found the "SYSCAT.TABDEP" catalog view in it, which seems to contain more or less what you asked for.
Database Backup/Restore Process
I suspect for anything not covered there you'll have to trawl through the rest of the syscat tables which are vast.

(Unfortunately I can't seem to link you to the exact page on SYSCAT.TABDEP itself, the search facility should lead you to it fairly easily though).. Most databases these days have a set of tables which contain data about the layout of your actual schema tables, quite handy for this sort of thing..
Not sure about FK & indexes though.
