table used by routine with language dependency - routine invalid
  on COMMIT

  Explanation:  There are one or more routines  that  depend  upon
  this   object  with  a  language  semantics  dependency.   Those
  routines will be  marked  invalid  and  need  to  be  recompiled
  through  the  language interface before reuse.  i.e.  the module
  will need to be extracted and re-created before this routine can
  be used.

  User Action:  Review your database design,  and  understand  the
  implications  of  this data definition language operation.  Roll
  back the transaction if you do  not  want  the  routines  to  be
  marked invalid.
