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
------------------------------windows 重启oracle
1、cmd进入
2、关闭：
lsnrctl stop
net stop OracleServiceORCL
3、开启：
lsnrctl start
net start OracleServiceORCL
修改用户密码
alter user sys identified by huozhe
----==============收回用户dba权限后=======
revoke dba from user_Name;
grant resource to username;
