Keywords

STORAGE

Specifies the database object’s physical storage characteristics.

INITIAL

Specifies the size of the first extent for the database object in bytes, kilobytes (K), or megabytes (M). If this size is not a multiple of the database block size, it will be rounded up to a multiple of the database block size.

NEXT

Specifies the size of the next extent for the database object in bytes, kilobytes (K), or megabytes (M). If this size is not a multiple of the database block size, it will be rounded up to a multiple of the database block size.

MINEXTENTS

Specifies the number of extents to be allocated when the database object is created. The minimum and default value is 1, except for rollback segments, which have a minimum and default of 2.

MAXEXTENTS

Specifies the maximum number of extents that may be allocated for the database object. The default varies according to the database block size. If the keyword UNLIMITED is specified, there is no upper limit to the number of extents allowed.

Specifies the percentage by which each extent grows over the previous extent. The default is 50, which means that each extent ...
