一、查看錶空間使用情況 SELECT SUM(bytes) / (1024 * 1024) AS free_space, tablespace_name FROM dba_free_space GROUP BY tablespace_name; SELECT a.tablespace_name, a.bytes total, b.bytes used, c.bytes free, (b.bytes * 100) / a.bytes "% USED ", (c.bytes * 100) / a.bytes "% FREE " FROM sys.smts_used b, sys.sm$ts_free c WHERE a.tablespace_name = b.tablespace_name AND a.tablespace_name = c.tablespace_name;
二、查看錶空間檔案（修改語句使用到） select tablespace_name, file_id, file_name, round(bytes/(1024*1024),0) total_space from dba_data_files order by tablespace_name
三、cmd命令 sqlplus sys as sysdba 執行下面語句 alter database datafile ‘C:\APP\ADMINISTRATOR\PRODUCT\12.1.0\DBHOME_1\DATABASE\SDE_TBS’ resize 8000m
