oracle初始化数据脚本

/*第1步：创建临时表空间  */

create temporary tablespace user_temp

size 50m

/*第3步：创建用户并指定表空间  */

create user username identified by 123456

/*第4步：给用户授予权限  */

grant connect,resource,dba to username;

/**是否设置为自动扩展*/
SELECT FILE_NAME,TABLESPACE_NAME,AUTOEXTENSIBLE FROM dba_data_files;

1.增加数据文件
ALTER TABLESPACE game
ADD DATAFILE '/oracle/oradata/db/GAME02.dbf' SIZE 1000M;

2.手动增加数据文件尺寸

--数据表空间
ALTER DATABASE DATAFILE '/oracle/oradata/db/GAME.dbf'
RESIZE 4000M;

--临时表空间

ALTER DATABASE TEMPFILE 'D:\oracle\oradata\DENE_TEMP.DBF'
RESIZE 2048M;

 

3.设定数据文件自动扩展
ALTER DATABASE DATAFILE '/oracle/oradata/db/GAME.dbf
AUTOEXTEND ON NEXT 100M
MAXSIZE 10000M;

查询索引占用了多少表空间
Select Segment_Name, Sum(bytes) / 1024 / 1024/1024 as Gsize From User_Extents Group By Segment_Name order by Gsize desc

----------删除用户以及表空间----------

DROP USER DAEN cascade;
 

drop tablespace DENE_DATA including contents and datafiles cascade constraint;

 

--------------------------导入dmp数据文件---------------------------------------------

1、把xxx.dmp文件放入D:\oracle\app\Administrator\admin\orcl\dpdump目录下

2、impdp daan/123456 DIRECTORY=DATA_PUMP_DIR DUMPFILE=xxx.dmp REMAP_SCHEMA=xx_test:daan remap_tablespace=TS_xx_DATA:DAAN_DATA table_exists_action=skip logfile=implog.log

或者如果不知道表空间与用户名

impdp pangu/123456 DIRECTORY=DATA_PUMP_DIR DUMPFILE=daen0615.dmp  TRANSFORM=SEGMENT_ATTRIBUTES:n table_exists_action=replace logfile=implog.log

or

impdp daen/asdqwe DIRECTORY=DATA_PUMP_DIR DUMPFILE=daen0615.dmp REMAP_SCHEMA="dene:daen" remap_tablespace="ANE_KD:DENE_DATA" remap_tablespace="TABLE_PERMANT:DENE_DATA" remap_tablespace="TS_ST_DATA:DENE_DATA" remap_tablespace="TABLE_STUDENT:DENE_DATA" remap_tablespace="TS_KJ_DATA:DENE_DATA" remap_tablespace="TS_SX_DATA:DENE_DATA" remap_tablespace="TABLE_TEST_HBH:DENE_DATA" remap_tablespace="TS_CJ_DATA:DENE_DATA" table_exists_action=replace logfile=implog.log
