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;
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。
