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 ULTIMUSDB
ADD DATAFILE '/oracle/oradata/db/ULTIMUSDB02.dbf' SIZE 1000M;
2.手动增加数据文件尺寸
ALTER DATABASE DATAFILE '/oracle/oradata/db/ULTIMUSDB.dbf' RESIZE 4000M;
3.设定数据文件自动扩展
ALTER DATABASE DATAFILE '/oracle/oradata/db/ULTIMUSDB.dbf'
AUTOEXTEND ON NEXT 100M
MAXSIZE 10000M;
