手工改变已存在文件大小
ALTER TABLESPACE app_data ADD DATAFILE
'D:\ORACLE\PRODUCT\10.2.0\ORADATA\EDWTEST\APP03.DBF' SIZE 20480M;
允许已存在的数据文件自动增长
ALTER DATABASE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\EDWTEST\APP03.DBF'
AUTOEXTEND ON NEXT 100M MAXSIZE 20480M;
增加数据文件
ALTER TABLESPACE SYSTEM ADD DATAFILE
'C:\APP\ORACLE\ORADATA\DFYYCDB\DATAFILE\O2_MF_SYSTEM_CWMNZ9XV_.DBF'
size 7167M autoextend on ;
ALTER TABLESPACE SYSTEM ADD DATAFILE
