无法在撤消表空间'UND_TBS'中将段扩展8

Question

我正在尝试将数据插入table1到现有表中table2.table1有3000万条记录.使用以下命令插入数据.一段时间后得到了给定的错误.

insert into TABLE2 (select * from TABLE1)
Error at Command Line:31 Column:0
Error report:
SQL Error: ORA-30036: unable to extend segment by 8 in undo tablespace 'UND_TBS'
30036. 00000 -  "unable to extend segment by %s in undo tablespace '%s'"

它表明, the specified undo tablespace has no more space available.

在重试操作之前,我该怎么办.是否有其他可用于成功插入数据的变通方法？

当@a_horse_with_no_name被注释掉时,

我已经创建了一个新的数据文件autoextend.

alter tablespace UND_TBS add datafile   '/path/my_data_file.dbf' size 7168M autoextend on;

路径可以通过以下方式识别:

select file_name from dba_data_files where tablespace_name ='UND_TBS';

你可以获得表空间的最大/自由大小,

SELECT b.tablespace_name,
  tbs_size SizeMb,
  a.free_space FreeMb
FROM
  (SELECT tablespace_name,
    ROUND(SUM(bytes)/1024/1024 ,2) AS free_space
  FROM dba_free_space
  GROUP BY tablespace_name
  ) a,
  (SELECT tablespace_name,
    SUM(bytes)/1024/1024 AS tbs_size
  FROM dba_data_files
  GROUP BY tablespace_name
  ) b
WHERE a.tablespace_name(+)=b.tablespace_name;
