Next-Extent Allocation

After the initial extent fills, the database server attempts to allocate another extent of contiguous disk space. The procedure that the database server follows is referred to as next-extent allocation.

Extents for a tblspace are tracked as one component of the tblspace tblspace information for the table. The maximum number of extents allocated for any tblspace is application and machine dependent because it varies with the amount of space available on the tblspace tblspace entry.
