Aborting command - invalid page <num> in area <str>

  Explanation:  An invalid page has been  detected  in  the  named
  storage  area causing the execution of the current command to be
  aborted.

  User Action:  Run RMU/VERIFY to  get  more  information  on  the
  corrupt  page.   The  database  administrator  should  create  a
  replacement storage area and use ALTER or DROP commands to  move
  other tables and indices out of the affected storage area.  Then
  use DROP STORAGE AREA to remove the unused area.  Alternatively,
  you can use the SQL EXPORT DATABASE and IMPORT DATABASE commands
  to rebuild the whole database.  Then execute  the  command  that
  was aborted.
