Pre-allocating extents is a static approach to the problem of preventing automatic allocation of extents by Oracle. You can pre-allocate extents to tables that have free list groups. This means that all free blocks are formatted into free lists, which will reside in the free list group of th...
For example, you could put tables with relatively high insert rates in a tablespace with a 10MB uniform extent size. On the other hand, you can place small tables with limited DML activity in a tablespace with a 100K uniform extent size. For an existing system where tablespaces are not orga...
