sequence table is full

  Explanation:  An attempt was made to create a  sequence  but  no
  room   remains  in  the  Rdb  root  file  for  further  sequence
  definitions.  Initially only 32 sequences can be  created  in  a
  new or converted database.

  User Action:  Use the ALTER DATABASE statement to  increase  the
  size  of  the  sequences  table  with the RESERVE ...  SEQUENCES
  clause.  Note that the value entered will be rounded to the next
  highest  multiple  of 32 so that a full page in the root file is
  used.
