Oracle数据库表空间删除报错误删除不了怎么办？

Posted 2023-05-02

主要由于我先在本地删除了表空间。导致数据库都登陆不了。现在我更改了数据库表空间，数据库没问题了。可删除的表空间和所涉及的用户都删除不了。都报这错误。怎么办。。。。。。。。。求大神指点

参考技术A 用sys登陆删除试试，如果还不行的话可能是您的oracle的服务没有停止，如果服务停止了还删除不了那就重新启动电脑然后停止服务，然后用sys登陆删除即可

Oracle删除表空间报ORA01548

由于undo表空间设置了自动增长，导致替换了好几个undo表空间，就想把原先的undo表空间删掉腾出空间

但删的时候报错

SQL> drop tablespace undotbs1 including contents and datafiles;
drop tablespace undotbs1 including contents and datafiles
*
ERROR at line 1:
ORA-01548: active rollback segment ‘_SYSSMU1_3780397527$‘ found, terminate
dropping tablespace

错误原因： 删除undo表空间中的segment需要回复 解决方法： 删除回滚段信息
这是因为分布式事务没有提交导致的吗，看看表空间段的情况

SQL> Select segment_id,segment_name,status,tablespace_name
from dba_rollback_segs where status not in(‘ONLINE‘,‘OFFLINE‘);  2

 发现undotbs1，2中的回滚段status为PARTLY AVAILABLE /NEED RECOVERY这时如果有rman备份可以利用rman恢复

没有的通过设置参数文件值解决：

SQL> create pfile from spfile;

添加该参数，并将需要恢复的段名放进去
