To load one SYSTEM 2000 database from another, use a view descriptor as input.
However, both databases cannot be in the same execution environment if
you request optimized load processing. To load one SYSTEM 2000 database from another,
one database must be in the single-user environment and the other database must be
in the
Multi-User environment. (Optimized load mode puts the database under
exclusive use, which excludes access to other databases in that environment until exclusive use
is terminated.)
