<p>有朋友找到我说应用访问数据库和导出数据都报ORA-01110 ORA-17070 OSD-04006之类错误,数据库可以正常open,但是业务访问关键数据和导出报错<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611175122.jpg"><img src="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611175122.jpg" alt="20220611175122" width="1152" height="405" class="alignnone size-full wp-image-9749" /></a><br />
<a href="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611175156.jpg"><img src="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611175156.jpg" alt="20220611175156" width="868" height="390" class="alignnone size-full wp-image-9750" /></a><br />
<hr />
对于这个错误,根据以往恢复经验,初步判断可能硬件异常(比如坏道,硬件故障)或者文件系统异常引起,让客户尝试拷贝该文件,确认该文件也无法拷贝<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611174852.jpg"><img src="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611174852.jpg" alt="20220611174852" width="657" height="444" class="alignnone size-full wp-image-9751" /></a><br />
<hr />
对于这种情况,如果放弃该文件,恢复其他文件数据,那样数据丢失比例太大,直接通过特定恢复工具对其损坏文件进行拷贝,最大限度强求当前文件数据,发现一些扇区损坏跳过继续拷贝<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611174928.jpg"><img src="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611174928.jpg" alt="20220611174928" width="1438" height="190" class="alignnone size-full wp-image-9752" /></a><br />
<hr />
通过坏块检查工具进行检查确认该文件76个block损坏(对于32G的数据文件损坏1M数据,比较好效果)<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611174909.png"><img src="https://www.xifenfei.com/wp-content/uploads/2022/06/20220611174909.png" alt="20220611174909" width="978" height="662" class="alignnone size-full wp-image-9753" /></a><br />
<hr />
对坏块进行处理,然后使用expdp导出数据,最大限度抢救数据<br />
