Oracle查看表空间及修改数据文件大小 第一步:查看所有表空间及表空间大小: select tablespace_name ,sum(bytes) / 1024 / 1024 as MB from dba_data_files group by tablespace_name; 第二步:查看所有表空间对应的数据文件: select tablespace_name,file_name from dba_data_files; 第三步:修改数据文件大小 alter database datafil

ORACLE如何查看表空间存储了那些数据库对象呢?可以使用下面脚本简单的查询表空间存储了那些对象: SELECT TABLESPACE_NAME AS TABLESPACE_NAME , SEGMENT_NAME AS SEGMENT_NAME , SUM(BYTES)/1024/1024 AS SEGMENT_SIZE FROM DBA_SEGMENTS WHERE TABLESPACE_NAME=&TABLESPACE_NAME GROUP
查看表空间剩余: ||'M' from dba_free_space group by tablespace_name 查看表空间总大小.使用大小.剩余大小,使用率.剩余率 ) useded, trunc(c.bytes) freeed from sys.sm$ts_avail a,sys.sm$ts_used b,sys.sm$ts_free c where a.tablespace_name = b.tablespace_name and a.tablespace_name = c.tabl
首先,可以通过下面的sql statement来查看表空间的使用情况.注意,该语句是在10g下测试过. SELECT FREE.TABLESPACE_NAME, FREE.FREE_SPACE/TOTAL.TOTAL_SPACE FROM (select TABLESPACE_NAME,sum(bytes)/1024/1024 AS FREE_SPACE from dba_free_space group by TABLESPACE_NAME) FREE, (select TABLESPACE_
