数据库的大小其实就是所有数据文件、联机日志文件及控制文件大小的和。
可以简单的的使用
select sum(bytes) from dba_data_file;
下而把几个较实用脚本贴上,是我常用的.
1、查看表空间的使用状况。
SELECT upper(f.tablespace_name) 表空间名,
d.Tot_grootte_Mb "表空间大小(M)",
d.Tot_grootte_Mb - f.total_bytes "已使用空间(M)",
round((d.Tot_grootte_Mb - f.total_bytes) / d.Tot_grootte_Mb * 100,2) "使用比",
f.total_bytes "空闲空间(M)",
f.max_bytes "最大块(M)"
FROM
(SELECT tablespace_name,
round(SUM(bytes)/(1024*1024),2) total_bytes,
round(MAX(bytes)/(1024*1024),2) max_bytes
FROM sys.dba_free_space
GROUP BY tablespace_name) f,
(SELECT dd.tablespace_name, round(SUM(dd.bytes)/(1024*1024),2) Tot_grootte_Mb
FROM sys.dba_data_files dd
GROUP BY dd.tablespace_name) d
WHERE d.tablespace_name = f.tablespace_name
ORDER BY 4 DESC
2、查看无法扩展的段
SELECT segment_name,
segment_type,
owner,
a.tablespace_name "tablespacename",
initial_extent/1024 "inital_extent(K)",
next_extent/1024 "next_extent(K)",
pct_increase,
b.bytes/1024 "tablespace max free space(K)",
b.sum_bytes/1024 "tablespace total free space(K)"
FROM dba_segments a,
(SELECT tablespace_name,MAX(bytes) bytes,SUM(bytes) sum_bytes FROM dba_free_space GROUP BY tablespace_name) b
WHERE a.tablespace_name=b.tablespace_name
AND next_extent>b.bytes
ORDER BY 4,3,1

select sum(bytes) from dba_data_file;
