Syntax options:

    SNAPSHOT EXTENT IS extent-pages PAGES | SNAPSHOT EXTENT IS
    (extension-options)

    Changes the number of pages of each snapshot or storage area file
    extent. The default extent for storage area files is 100 pages.

    Specify a number of pages for simple control over the file
    extent. For greater control, and particularly for multivolume
    databases, use the MINIMUM, MAXIMUM, and PERCENT GROWTH extension
    options instead.

    If you use the MINIMUM, MAXIMUM, and PERCENT GROWTH parameters,
    you must enclose them in parentheses.
