When you are defining storage areas and extents in order to create a new database:
The minimum information required in a .st file is one schema area extent definition statement and one primary recovery (BI) area extent definition statement.
The minimum information needed to specify any extent is the storage area type and extent pathname. For example:
# Primary Recovery Area
b .
# Schema Area
d .
If you do not define a primary recovery extent path in the .st file, the PROSTRCT CREATE utility generates an error.
You cannot use any of the reserved storage area names as application data storage area names.
