Many thanks for reply!
But I referenced about data dbspace; so how many tables for data dbspaces, or which tables in each datadbs?? (without take in account rootdbs, logdbs, phydbs, indexdbs, tempdbs1, tempdbs2...)
Good, it does not have as to define an amount of tables for dbspaces.
The recommended one is separates the tables that tend to grow very, of the proper others, creating if necessary, dbspaces for each one.
I know that not aid very, but I go to see if I find a model and you sending.
