Oracle查看表空间、是否开启扩展

工作中经常会遇到正在跑存储过程报表空间不足的错误，查询方法如下

1、oracle查看表空间使用情况

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、oracle是否开启自动扩展

SELECT T.TABLESPACE_NAME,
       D.FILE_NAME,
       D.AUTOEXTENSIBLE,
       D.BYTES,
       D.MAXBYTES,
       D.STATUS
  FROM DBA_TABLESPACES T, DBA_DATA_FILES D
 WHERE T.TABLESPACE_NAME = D.TABLESPACE_NAME
 ORDER BY TABLESPACE_NAME, FILE_NAME;
