ora-01653表空間擴展失敗產生的場景和處理方法

產生ora-01653表空間擴展失敗的過程：

DBF放在Ｅ盤且Ｅ盤只有剩余的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.增加數據

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異常出現。

處理辦法：

先清空E盤空間到2G

查：dbf空間是否是自動增長。

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) "表空間名",
D.TOT_GROOTTE_MB "表空間大小(M)",
D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空間(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 "空閒空間(M)",
F.MAX_BYTES "最大塊(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;

確定後，執行：

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

解決。
