  ****************************************************************
  With Db2 12, the LOAD utility updates the MAXASSIGNEDVAL for
  user-provided input. This is in contrast to Db2 11, which did
  not maintain MAXASSIGNEDVAL for such LOAD scenarios. Db2 12
  users presently have no way to revert to the prior behavior.
  

Problem conclusion

Temporary fix

Comments

• A new keyword UPDMAXASSIGNEDVAL with options YES or NO will
  be added to the LOAD utility. This will allow users to decide
  whether to maintain and update the SYSIBM.SYSSEQUENCE
  catalog MAXASSIGNEDVAL value relating to the identity columns
  based on the input identity column values loaded.
  PH28476 introduces the following changes to externals:
  LOAD utility syntax diagram change:
           .-UPDMAXASSIGNEDVAL-YES-.
  >>-LOAD----------------------------->
           '-UPDMAXASSIGNEDVAL-NO--'
  UPDMAXASSIGNEDVAL
       Specifies whether LOAD updates the MAXASSIGNEDVAL column
       in the SYSIBM.SYSSEQUENCES catalog table for identity
       columns.
  YES
       Specifies that LOAD updates MAXASSIGNEDVAL when the
       loaded value for the identity column is greater or
       smaller than the current value of MAXASSIGNEDVAL,
       depending on whether ascending or descending sequencing
       is in use. YES is the default.
  NO
       Specifies that LOAD does not update MAXASSIGNEDVAL
       regardless of the value of the loaded identity column.
  Special note
       Although you can specify this option in Db2 11,
       UPDMAXASSIGNEDVAL has no effect until Db2 12.
