After creating the archive, create new dbspaces .
- Create two new main dbspaces, D and
E.
- Continue using the database db.db as a
production database.
-
The database objects (tables, indexes, and so on)
that existed as of time t0
may have changed so that db.db does not equal db.db0.
-
The database db.db continues to read data from dbspaces
A, B, and C as long as the tables that existed at time
t0 exist and as long as
they contain some unmodified rows of data that existed as of
time t0.
-
Even if or when this is no longer true, db.db continues to open A, B and C
unless they are dropped from db.db, which is allowed only if they are empty
from db.db's point of
view.
