What is a Locally Managed Tablespace?

1 Answer

Answer :

Locally Managed Tablespace is a tablespace that record extent allocation in the tablespace header. Each tablespace manages its own free and used space within a bitmap structure stored in one of the tablespace's  data files.
Advantages of Locally Managed Tablespaces:
▪ Eliminates the need for recursive SQL operations against the data dictionary (UET$ and FET$ tables) ▪ Reduce contention on data dictionary tables (single ST enqueue)
▪ Locally managed tablespaces eliminate the need to periodically coalesce free space (automatically tracks  adjacent free space)
▪ Changes to the extent bitmaps do not generate rollback information
