1.create tablespaces
sql> create tablespace ts_name datafile 'c:\oracle\oradata\file1.dbf' size 100m ,
sql>'c:\oracle\oradata\file2.dbf' size 100m minimum extent 550k [logging/nologging]sql> default storage (initial 500k next 500k maxextents 500 pctinccease 0)
sql> [online/offline] [permanent/temporary] [extent_management_clause]
2.locally managed tablespace
sql> create tablespace user_data datafile 'c:\oracle\oradata\user_data01.dbf'
sql> size 500m extent management local uniform size 10m;
3.temporary tablespace
sql> create temporary tablespace temp tempfile 'c:\oracle\oradata\temp01.dbf'
sql> size 500m extent management local uniform size 10m;
4.change the storage setting
sql> alter tablespace app_data minimum extent 2m;
sql> alter tablespace app_data default storage(initial 2m next 2m maxextents 999);
5.taking tablespace offline or online
sql> alter tablespace app_data offline;
sql> alter tablespace app_data online;
6.read_only tablespace
sql> alter tablespace app_data read only|write;
7.droping tablespace

8.enableing automatic extension of data files
sql> alter tablespace app_data add datafile 'c:\oracle\oradata\app_data01.dbf' size 200m
sql> autoextend on next 10m maxsize 500m;
9.change the size fo data files manually
sql> alter database datafile 'c:\oracle\oradata\app_data.dbf' resize 200m;
10.Moving data files: alter tablespace
sql> alter tablespace app_data rename datafile 'c:\oracle\oradata\app_data.dbf
sql> to 'c:\oracle\app_data.dbf';
