4.undo表空间至少需要200MB,需要8.4G硬盘空间
如何计算需要多少undo空间
SELECT SUM(DECODE(autoextensible,'YES',200*1024*1024+1,bytes)) total
FROM dba_data_files f, dba_tablespaces s
WHERE s.contents = 'UNDO'
AND s.tablespace_name = f.tablespace_name;

alter database datafile '/u01/app/oracle/oradata/orcl/undotbs01.dbf' resize 250M;
