Specifies parameters that control the characteristics of database
    storage area files. You can specify most storage area parameters
    for either single-file or multifile databases, but the effect of
    the clauses differs.

    o  For single-file databases, the storage area parameters
       specify the characteristics for the single storage area in
       the database.

    o  For multifile databases, the storage area parameters specify
       a set of default values for any storage areas created by the
       IMPORT statement that do not specify their own values for
       the same parameters. The attributes of a storage area are
       supplied by the interchange file unless redefined by the
       IMPORT statement. The default values apply to the storage
       area named in CREATE STORAGE AREA database elements.

       For details about storage area parameters, see the CREATE
       STORAGE_AREA clause.

                                      NOTE

          The CREATE STORAGE AREA clauses can override these
          default values. The default values do not apply to any
          storage areas created later with the ALTER DATABASE
          statement.
