Oracle：常用操作

1.导入数据，创建表空间和用户：

/*第1步：创建临时表空间 **/


create temporary tablespace user_temp1 
tempfile 'D:\app\Administrator\oradata\shengrensheting\user_temp1.dbf' 
size 50m 
autoextend on 
next 50m maxsize 30480m 
extent management local;

/*第2步：创建数据表空间 */


create tablespace user_data1 
logging 　　　　　　　　　　　　　　　　/*logging 是对象的属性，创建数据库对象时，oracle 将日志信息记录到练级重做日志文件中。代表空间类型为永久型 */
datafile 'D:\app\Administrator\oradata\shengrensheting\user_data1.dbf' 
size 50m 
autoextend on                               /*autoextend on    表空间大小不够用时自动扩展*/
next 50m maxsize 30480m 　　　　/*next 50m 自动扩展增量为50MB */
extent management local;　　　　/*extent management local   代表管理方式为本地*/



/*创建拓展表空间*/
CREATE TABLESPACE TS_HNDSZG_PUBLIC  
    LOGGING  DATAFILE 
    'E:\oracle\scdb\scdb\TS_HNDSZG_PUBLIC01.DBF' SIZE 1000M AUTOEXTEND ON NEXT  1000M MAXSIZE Unlimited,
    'E:\oracle\scdb\scdb\TS_HNDSZG_PUBLIC02.DBF' SIZE 1000M AUTOEXTEND ON NEXT  1000M MAXSIZE Unlimited,
    'E:\oracle\scdb\scdb\TS_HNDSZG_PUBLIC03.DBF' SIZE 1000M AUTOEXTEND ON NEXT  1000M MAXSIZE Unlimited,
    'E:\oracle\scdb\scdb\TS_HNDSZG_PUBLIC04.DBF' SIZE 1000M AUTOEXTEND ON NEXT  1000M MAXSIZE Unlimited,
    'E:\oracle\scdb\scdb\TS_HNDSZG_PUBLIC05.DBF' SIZE 1000M AUTOEXTEND ON NEXT  1000M MAXSIZE Unlimited
    EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT  AUTO ;


-----------------------------------------------------------------------
/*或执行导入，提示的时候增加表空间*/
ALTER TABLESPACE USERS  ADD DATAFILE 

  'D:\aysb_yiliao\users1 .ORA' SIZE 512M AUTOEXTEND ON maxsize  UNLIMITED,
  'D:\aysb_yiliao\users2 .ORA' SIZE 512M AUTOEXTEND ON maxsize UNLIMITED,
  'D:\aysb_yiliao\users3 .ORA' SIZE 512M AUTOEXTEND ON maxsize UNLIMITED,
  'D:\aysb_yiliao\users4 .ORA' SIZE 512M AUTOEXTEND ON maxsize UNLIMITED,
  'D:\aysb_yiliao\users5 .ORA' SIZE 512M AUTOEXTEND ON maxsize UNLIMITED,
  'D:\aysb_yiliao\users6 .ORA' SIZE 512M AUTOEXTEND ON maxsize UNLIMITED



/*第3步：创建用户并指定表空间 */

create user CXJMYLBX identified by 123456
default tablespace user_data1 
temporary tablespace user_temp1;

 


/*第4步：给用户授予权限 */

grant connect,resource,dba to CXJMYLBX;

2.Oracle导入命令：

imp username/password@dataBase file='' log='' ignore=y full=y fromuser= touser=
