Tablespace extent management | ||
Dictionary managed
The allocation of extents within the tablespace is managed through the dictionary tables
uet$ and fet$.
If the system tablespace is not dictionary managed, it has the following
implications:
Locally managed
The allocation of extents within the tablespace is managed through bits (which are stored within the tablespace itself). Each bit
corresponds to an extent.
Autoallocate
Oracle will choose extent sizes.
Uniform
All extent sizes within such a tablespace are equal in size.
