Re: Locally managed tablespace

A Locally Managed Tablespace is a tablespace that manages its own extents maintaining a bitmap in each datafile to keep track of the free or used status of blocks in that datafile. Each bit in the bitmap corresponds to a block or a group of blocks. When the extents are allocated or freed for reuse, Oracle changes the bitmap values to show the new status of the blocks. These changes do not generate rollback information because they do not update tables in the data dictionary (except for tablespace quota information), like the default method of Dictionary - Managed Tablespaces does.
