Oracle创建表空间

建立表空间并设置为默认表空间（最大32GB）

1.    create temporary tablespace test tempfile '/home/oracle/oradata/abc/test.dbf' size 50m autoextend on next 50m maxsize 20480m extent management local
2.    create tablespace test_data logging datafile '/home/oracle/oradata/abc/test_data.dbf' size 50m autoextend on next 50m maxsize 20480m extent management local
3.    alter user train default tablespace test_data
4.    alter user train quota 0 on system

查询当前数据库所有表空间

select tablespace_name from dba_data_files; //查询当前数据库所有表空间

创建大表空间（最大32TB）

create bigfile tablespace train_test datafile '/home/oracle/oradata/abc/train_test.dbf' size 50m autoextend off extent management local uniform size 1m segment space management auto;
