Oracle表空间管理 ORA-01653 错误
查询表空间使用情况
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;

查看表空间是否具有自动扩展的能力
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;

?修改表空间文件扩展方式:???
ALTER DATABASE DATAFILE 'D:\ORACLE\ORADATA\ORCL\ORCL_DATA.DBF' AUTOEXTEND ON NEXT 50M MAXSIZE UNLIMITED
?
'D:\ORACLE\ORADATA\ORCL\ORCL_DATA.DBF'? 是第二步中的FILE_NAME
