Create tablespace in Oracle

The create tablespace statement is used to create a tablespace.

Permanent tablespace

create tablespace ts_something  logging  datafile '/dbf1/ts_sth.dbf'   size 32m   autoextend on   next 32m maxsize 2048m  extent management local;

create tablespace data datafile '/home/oracle/databases/ora10/data.dbf'size                                  10Mautoextend on maxsize                200Mextent management local uniform size  64K;

Temporary tablespace

create temporary tablespace temp_mtr   tempfile '/dbf1/mtr_temp01.dbf'   size 32m   autoextend on   next 32m maxsize 2048m  extent management local;

Note, a temporary tablespace has tempfiles, not datafiles.

Undo tablespace

create undo tablespace ts_undo  datafile '/dbf/undo.dbf'   size 100M;

Misc

More than one datafile can be created with a single create tablespace command:

create tablespace ts_sth   datafile 'c:\xx\sth_01.dbf' size 4M autoextend off,           'c:\xx\sth_02.dbf' size 4M autoextend off,           'c:\xx\sth_03.dbf' size 4M autoextend off  logging  extent management local;

Adding a tablespace to a database is a structural change that requires a backup.
