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.STATUSFROM DBA_TABLESPACES T,DBA_DATA_FILES DWHERE T.TABLESPACE_NAME =D.TABLESPACE_NAMEORDER 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_BYTESFROM SYS.DBA_FREE_SPACEGROUP BY TABLESPACE_NAME) F,(SELECT DD.TABLESPACE_NAME,ROUND(SUM(DD.BYTES) / (1024 * 1024), 2) TOT_GROOTTE_MBFROM SYS.DBA_DATA_FILES DDGROUP BY DD.TABLESPACE_NAME) DWHERE D.TABLESPACE_NAME = F.TABLESPACE_NAMEORDER BY 4 DESC;确定后，，执行：
ALTER DATABASEDATAFILE 'E:\DATA_DATA.DBF' AUTOEXTENDON NEXT 50M MAXSIZE UNLIMITED
解决。
选择逃避，选择被动的去面对生活
