早上做個實驗,update數據的時候報錯ora-30036:無法按8擴展段（在還原表空間‘undotbs_new’中）
1.查詢了一下undo表空間的使用,發現已經超過了80%
SELECT a.tablespace_name as tablespace_name,
to_char(b.total/1024/1024,999999.99) as Total,
to_char((b.total-a.free)/1024/1024,999999.99) as Used,
to_char(a.free/1024/1024,999999.99) as Free,
to_char(round((total-free)/total,4)*100,999.99) as Used_Rate
FROM (SELECT tablespace_name, sum(bytes) free FROM DBA_FREE_SPACE GROUP BY tablespace_name) a,
(SELECT tablespace_name, sum(bytes) total FROM DBA_DATA_FILES GROUP BY tablespace_name ) b
WHERE a.tablespace_name=b.tablespace_name
AND a.tablespace_name='UNDOTBS_NEW'
ORDER BY a.tablespace_name;
2.將undo表空間大小重新加大點,解決問題~
alter database datafile 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\SUREDD\UNTOTBS_NEW_01.DBF' resize 2048M;
