  ****************************************************************
  Db2 fails to execute the before trigger or after trigger
  actions when running the SQL UPDATE statement.
  The failure occurs only when triggers are created after the
  UPDATE statement is bound.
  
  The reason of the failure is that the bind time optimized
  UPDATE code (UPROC) has not generated instruction to set the
  bit map for the columns being updated. As a result, Db2 fails
  to execute the expected triggers action.
  

Problem conclusion

• Db2 has been modified to set the bit map for the updated
  columns when the triggers are created after the UPDATE
  statement is bound.
  

Temporary fix
