Syntax options:

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

 Specifies the number of pages of each snapshot or storage area file
 extent. The default extent for storage area files is 99 pages.

    Specify a number of pages for simple control over the extension.
    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.
