不当恢复truncate数据导致数据库不能open处理

惜分飞 — Fri, 30 Jan 2026 12:05:52 +0000

有客户误truncate操作干掉了数据库中的几张表,然后尝试通过FY_Recover_Data进行恢复,恢复到一半然后终止了,数据库结果就起不来了(具体什么原因不知道,肯定是各种不合适的操作引起的故障),我接手故障的时候,数据库被强制resetlogs,报ORA-600 2662错误

通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)脚本检查发现有文件被offline,且resetlogs 信息不对

通过obet工具(Oracle数据块编辑工具( Oracle Block Editor Tool)-obet)对resetlogs相关信息进行修改

OBET> set mode edit

OBET> set file 18

然后尝试打开库,报ORA-600 kdourp_inorder2错误

该报错比较明显是由于undo回滚段异常导致,通过屏蔽回滚段,open库成功.后续对客户truncate的表进行分析,比较悲催由于没有第一时间保护现场而且对所在表空间进行了大量写入操作,导致truncate数据恢复较少.
