How do I view the table space oracle data dictionary space management or local management space?
Dba_tablespaces can check this table to see a table space is a dictionary management or local management, the corresponding field for extent_management, if the value is compared with the dictionary DICTIONARY management, value for LOCAL is the local management.
Which can not be said to have a good idea of their scope of application, as follows:
1, system table space can only be a data dictionary management, 9i is the same, do not discuss this.
2, the general distribution and recycling of space such as frequent temp table space with local management, mainly in order to reduce the space allocated to wait and fight for the use of the data dictionary.
3, the regular insert, delete, update the table space can be used for local management of space, but this is not too relevant, and personal views.
4, the normal practice is to not temp table space for local management, and its use in this data dictionary management.
select tablespace_name, extent_management from dba_tablespaces;
