Extent Management

Indicates the method used for managing extents in this tablespace:

Allocation Type

The type of extent allocation to be used for this tablespace.

Force Logging

Indicates if the tablespace is in Force Logging mode, which logs all changes to all objects in the tablespace, except changes to temporary segments. The possible values are Yes and No.

Logging

Indicates if a redo log is to be generated for the tablespace.

The possible values are Logging and No.
