1、我们先查询表空间的占用情况,使用sql如下:
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)", to_char(round((d.tot_grootte_mb - f.total_bytes) / d.tot_grootte_mb * 100, 2), '990.99') "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、查询表空间的数据文件的路径,使用sql如下:
select t.* from sys.dba_data_files t where t.tablespace_name ='PACS31';
