Meathod1:给表空间增加数据文件
- ALTER TABLESPACE app_data ADD DATAFILE
- 'D:ORACLEPRODUCT10.2.0ORADATAEDWTESTAPP03.DBF' SIZE 50M;
Meathod2:新增数据文件,并且允许数据文件自动增长
- ALTER TABLESPACE app_data ADD DATAFILE
- 'D:ORACLEPRODUCT10.2.0ORADATAEDWTESTAPP04.DBF' SIZE 50M
- AUTOEXTEND ON NEXT 5M MAXSIZE 100M;
Meathod3:允许已存在的数据文件自动增长
- ALTER DATABASE DATAFILE 'D:ORACLEPRODUCT10.2.0ORADATAEDWTESTAPP03.DBF'
- AUTOEXTEND ON NEXT 5M MAXSIZE 100M;
Meathod4:手工改变已存在数据文件的大小
- ALTER DATABASE DATAFILE 'D:ORACLEPRODUCT10.2.0ORADATAEDWTESTAPP02.DBF'
- RESIZE 100M;
