TABLESPACE USAGE

Посмотреть, как табличные пространства связаны с файлами данных можно так:
(DBA_FREE_SPACE, позволяет определить, сколько свободного места осталось в нашем табличном пространстве.) 



BREAK ON tablespace_name SKIP 2
COMPUTE SUM OF allocated_bytes, free_bytes ON tablespace_name
COLUMN allocated_bytes FORMAT 9,999,999,999
COLUMN free_bytes FORMAT 9,999,999,999

SELECT a.tablespace_name,
       a.file_name,
       a.bytes allocated_bytes,
       b.free_bytes
 FROM dba_data_files a,
     (SELECT file_id, SUM(bytes) free_bytes
      FROM dba_free_space b GROUP BY file_id) b
WHERE a.file_id=b.file_id
ORDER BY a.tablespace_name;

Иногда может наблюдаться замедление работы запросов при обращении к DBA_FREE_SPACE, а также появление чрезмерного ожидания операций ввода-вывода.
Для решения этой проблемы нужно:

Удалить содержимое корзины

connect / as sysdba
select count(*) from dba_recyclebin;
purge dba_recyclebin;

Собрать статистику для X$KTFBUE

connect / as sysdba
EXEC DBMS_STATS.GATHER_TABLE_STATS(OWNNAME =>'SYS', TABNAME => 'X$KTFBUE',ESTIMATE_PERCENT=>100);

Проверяем:

column owner format a6
column table_name format a10
column last_anal format a10
SELECT owner,  table_name,  last_analyzed FROM dba_tab_statistics WHERE table_name='X$KTFBUE';
