增加表空間大小的四種方法

Meathod1：給表空間增加數(shù)據(jù)文件

ALTER TABLESPACE app_data ADD DATAFILE

'D:\ORACLE\PRODUCT\10.2.0\ORADATA\EDWTEST\APP03.DBF' SIZE 50M;

Meathod2：新增數(shù)據(jù)文件，并且允許數(shù)據(jù)文件自動(dòng)增長(zhǎng)

ALTER TABLESPACE app_data ADD DATAFILE

'D:\ORACLE\PRODUCT\10.2.0\ORADATA\EDWTEST\APP04.DBF' SIZE 50M

AUTOEXTEND ON NEXT 5M MAXSIZE 100M;

Meathod3：允許已存在的數(shù)據(jù)文件自動(dòng)增長(zhǎng)

ALTER DATABASE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\EDWTEST\APP03.DBF'

AUTOEXTEND ON NEXT 5M MAXSIZE 100M;

Meathod4：手工改變已存在數(shù)據(jù)文件的大小

ALTER DATABASE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\EDWTEST\APP02.DBF'

RESIZE 100M;
