AUTOEXTEND oN
the Next MAXSIZE 20480m 50m
extent management local;
create tablespace TORN
logging
datafile 'D:\oracledata\TORN.dbf'
size 50m
autoextend on
next 50m maxsize 20480m
extent management local;
创建用户及指定表空间
CREATE USER TORN PROFILE "DEFAULT" IDENTIFIED BY "TORN" DEFAULT TABLESPACE "TORN" TEMPORARY TABLESPACE "TEMP_TORN" ACCOUNT UNLOCK;
