我在尝试从备份表中插入数据时遇到错误。
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'"
要解决此问题，我已将新的空数据文件创建到相应的路径。 之后，我在尝试执行任何选择/删除操作时收到以下给出的错误。
Error at Command Line:1 Column:0
Error report:
SQL Error: ORA-01115: IO error reading block from file (block # )

01115. 00000 - "IO error reading block from file %s (block # %s)"
*Cause: Device on which the file resides is probably offline
*Action: Restore access to the device
我检查了ONLINE文件的状态。
知道如何修复此错误？
