oracle-表空间满了

一、查看

select a.tablespace_name,a.bytes/1024/1024 "sum MB",
(a.bytes-b.bytes)/1024/1024 "used MB",b.bytes/1024/1024 "free MB",
round (((a.bytes-b.bytes)/a.bytes)*100,2) "used%" from
(select tablespace_name,sum(bytes) bytes from dba_data_files group by tablespace_name) a,
(select tablespace_name,sum(bytes) bytes,max (bytes) largest from dba_free_space group by tablespace_name)b
where a.tablespace_name=b.tablespace_name
order by ((a.bytes-b.bytes)/a.bytes) desc;

TABLESPACE_NAME	sum MB	used MB	free MB	used%
SEC_D	32767	32760	7	99.97

二、增加

查看使用率，没满则：

①查看是否自动扩容

select tablespace_name,file_name,autoextensible from dba_data_files where tablespace_name = 'SEC_D'

TABLESPACE_NAME	FILE_NAME	AUT
SEC_D	C:\orcl\sec_d01.dbf	NO

②没有，则修改为自动

alter database datafile 'C:\orcl\sec_d01.dbf' autoextend on

满了，则：

①增加一个

ALTER TABLESPACE SEC_D ADD DATAFILE 'C:\orcl\sec_d02.dbf' SIZE 32767M;//最大32G
