1、我們先查詢表空間的占用情況,使用sql如下:
select upper(f.tablespace_name) "表空間名", d.tot_grootte_mb "表空間大小(M)", d.tot_grootte_mb - f.total_bytes "已使用空間(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 "空閑空間(M)", f.max_bytes "最大塊(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、查詢表空間的數據文件的路徑,使用sql如下:
select t.* from sys.dba_data_files t where t.tablespace_name ='PACS31';
