(1)查看表空間
SELECT a.tablespace_name "表空間名",total 表空間大小,free 表空間剩余大小,
(total-free) 表空間使用大小,
ROUND((total-free)/total,4)*100 "使用率 %"
FROM (SELECT tablespace_name,SUM(bytes) free FROM DBA_FREE_SPACE
GROUP BY tablespace_name ) a,
(SELECT tablespace_name,SUM(bytes) total FROM DBA_DATA_FILES
GROUP BY tablespace_name) b
WHERE a.tablespace_name=b.tablespace_name;
(2)增加表空間文件
alter tablespace tsname add datafile 'e:\datafile_name.dbf" size xxM;
