产生ora-01653表空间扩展失败的过程：

DBF放在Ｅ盘且Ｅ盘只有剩余的２００Ｍ

--1.建表

DROP TABLE bigtab;

CREATE TABLE bigtab AS SELECT rownum as "id", a.* FROM dba_objects a;

DROP TABLE smalltab;
 create table smalltab as select rownum as "id", a.* FROM dba_tables a;

--2.增加数据

 DECLARE
       n NUMBER;
    BEGIN
       FOR n IN 1..100
       LOOP
           INSERT INTO bigtab SELECT rownum as "id", a.* FROM dba_objects a;
       END LOOP;
       
       COMMIT;
   END;
//ora-01653异常出现。

处理办法：

先清空E盘空间到2G

查：dbf空间是否是自动增长。

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;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;

确定后，执行：

ALTER DATABASE DATAFILE 'E:\DATA_DATA.DBF' AUTOEXTEND ON NEXT 50M MAXSIZE UNLIMITED

解决。
