Improvement in IBM i 7.3 and IBM i 7.4:

The Database cross-reference processing is improved to only rebuild SQL based database catalogs when needed.

Improvement only in IBM i 7.4:

A portion of the Database cross-reference processing is processed asynchronously to the VARY ON, yielding a much faster vary ON.


You can review Database IASP vary on before and after timing via this query:

select v.*
  from qsys2.asp_vary_info v
  where operation_type = 'VARY ON' and step like '%Database%'
  order by duration desc;
