oracle创建表空间

扩展表空间 首先查看表空间的名字和所属文件 select tablespace_name, file_id, file_name, round(bytes/(1024*1024),0) total_space from dba_data_files order by tablespace_name; 1.增加数据文件 ALTER TABLESPACE game ADD DATAFILE ‘/oracle/oradata/db

扩展表空间

首先查看表空间的名字和所属文件

select tablespace_name, file_id, file_name,
round(bytes/(1024*1024),0) total_space
from dba_data_files
order by tablespace_name;

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
ALTER DATABASE DATAFILE ‘/oracle/oradata/db/GAME.dbf’
RESIZE 4000M;

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;

设定后查看表空间信息

SELECT A.TABLESPACE_NAME,A.BYTES TOTAL,B.BYTES USED, C.BYTES FREE,
(B.BYTES*100)/A.BYTES “% USED”,(C.BYTES*100)/A.BYTES “% FREE”
FROM SYS.SM$TS_AVAIL A,SYS.SM$TS_USED B,SYS.SM$TS_FREE C
WHERE A.TABLESPACE_NAME=B.TABLESPACE_NAME AND A.TABLESPACE_NAME=C.TABLESPACE_NAME;
