Question

我在Windows 2008 Server上安装了oracle 11G。我有一个700GB的大文件表空间。我在一个用户“ARCHIVE”中拥有所有数据/表。使用exp命令导出数据库时。它会产生以下错误：

EXP-00056: ORACLE error 1115 encountered
ORA-01115: IO Error reading block from file 6 (block # 75593959)
ORA-27070: async read/write failed
ORA-04016: Error queuing an asynchronous I/O request.
O/S-Error: (OS 23) Data error (cyclic redundancy check)

导出数据库的安全方法是什么？

Answer 1

您可以排除这一个表（TBL_INTER_DATA）并重试。如果TBL_INTER_DATA对您很重要，您可以尝试将未损坏的部分内容TBL_INTER_DATA保存为CSV文件（使用行号查找和跳过损坏的块）。
